OSHUG 62 — RISC-V, RISC-V, RISC-V, Thursday 23rd November.
by Andrew Back 08 Nov '17

08 Nov '17

Hello, Details can be found below for the 62nd meeting, the theme for which is the RISC-V open ISA. Regards, Andrew // Event #62 — RISC-V, RISC-V, RISC-V On the 23 November 2017, 18:00 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/62 The sixty-second meeting will be on the theme of RISC-V, an open ISA which started life at the University of California, Berkeley. A joint meeting with the BCS Open Source Specialist Group. — Bringing up cycle-accurate models of RISC-V cores The openness of the RISC-V ISA has enabled the development of many open-source RISC-V cores with varying capabilities. Choosing an implementation that meets given requirements can be done to some extent by comparing specifications and other attributes of the cores, but any decision must be based on actual testing. Using Verilator to generate cycle-accurate models enables rapid development of testing platforms. This talk provides a report of our experience bringing up cycle-accurate models of two cores in particular, RI5CY from the PuLP project, and Clifford Wolf's PicoRV32. For testing, a software ecosystem consisting of a compiler, binary utilities, debugger, and an interface between the model and debugger accompanies the Verilator model. To compare the cores, we used the GCC test suite and the RISC-V ISA test suite for measuring correctness, and the Bristol/Embecosm Embedded Benchmark Suite (BEEBS) to compare performance. All code and scripts used for the implementation are open-source, and can be re-used by others who wish to do similar exercises with other RISC-V cores. * Edward Jones has a background in parsing techniques and works at Embecosm on LLVM and GNU toolchains. He is also involved in research by Embecosm to investigate ways in which the software tool chain can reduce program energy consumption. Edward Jones is a Computer Science graduate of the University of Kent. — FreeBSD/RISC-V and Device Drivers The FreeBSD port to RISC-V 64-bit ISA was added in January 2016. FreeBSD is the first operating system that officially supported RISC-V in the main repository. Since its introduction, support has evolved, RISC-V privileged architecture has updated a few times. The platform is maturing making it suitable for general, commercial, research and educational use. The GCC v7.0 target for RISC-V was officialy upstreamed and NVIDIA is planning to ship all of their GPUs with RISC-V coprocessor enabled in the future. Several companies have announced the start of RISC-V chip development and many universities are taking RISC-V as a target architecture for doing research. The world first RISC-V microcontroller-class board HiFive1 was released and we are getting closer to the first general purpose board to become available! This talk will describe the current status of FreeBSD/RISC-V, toolchain and supported simulators. The porting process as well as describing the latest changes made to FreeBSD in order to support the latest RISC-V privilege specification (v1.10). This includes enabling by default FDT support and drivers attachment change, SBI interface, compiler flags/built-in definition changes, support for updated BBL boot loader, RISC-V privilege levels, initial page tables build, page table entry flags and other changes. An overview of FreeBSD device drivers subsystem will also be covered describing the device frameworks, buses and kernel-interfaces that exists in FreeBSD (e.g. Newbus, cdevsw, bus_dma, SYSINIT, vt, sound, ifnet, spibus, etc), how to use and configure them and how to debug a device driver. This should answer the question: How to write device driver for FreeBSD/RISC-V? * Ruslan Bukin is a Research Associate at University of Cambridge Computer Laboratory. He has been a FreeBSD user since 2002 and src committer since 2013. His main interests and contributions to FreeBSD are related to computer architectures support, performance monitoring technologies support, hardware tracing technologies (Intel PT), devicedrivers, DMA engines and DMA frameworks, hardware security (Intel SGX, CHERI), heterogeneous computing. Ruslan is the lead developer of the FreeBSD/RISC-V project. He obtained a Computer Science degree in 2008 from Peoples' Friendship University of Russia in Moscow — Talk #3 TBA Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.

OSHUG 61 — Reimagining EDSAC, NetBSD Updates, Semantic & Change Coupling of Software Classes, Thurs 19th October.
by Andrew Back 10 Oct '17

10 Oct '17

Hello, Details can be found below for the 61st meeting, which is in just over a week, so please don't delay in registering if you plan to attend. Best, Andrew // Event #61 — OSSG AGM, Reimagining EDSAC, NetBSD Updates, Semantic and Change Coupling of Software Classes. On the 19 October 2017, 18:00 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/61 The meeting this month will start with the BCS OSSG AGM and this will be followed by a talk on recent and planned improvements to NetBSD, a report from Chip Hack EDSAC Challenge, and finally a talk on the interplay between semantic coupling and co-change of software. — BCS Open Source SG - AGM All members of OSHUG are welcome to attend and OSHUG members are encouraged to put themselves forward to join the committee. In particular we would welcome anyone to join the event organizers who arrange the speakers for each month and the occasional all-day workshops. Currently we have Sevan Janiyan, @ndy Bennett and Andrew Back as event organizers on the committee. — Updates to the NetBSD operating system since OSHUG #57 & #58 Since the workshops held earlier this year, numerous changes have been made to the NetBSD operating system to ensure future workshops are easier for users and work smoother from the outset. This talk will cover some of the improvements made so far and what's currently in the works. >From wrestling with the u-boot firmware to new tools included in the os and much more. * Sevan Janiyan is founder of Venture 37, which provides system administration & consultancy services. As a fan of operating systems and computers with different CPU architectures, in his spare time he maintains builds of open source software on a variety of systems featuring PowerPC, SPARC and armv7l CPUs. He hopes to own a NeXTcube & OMRON LUNA-88K2 one day. — Reimagining EDSAC: The ChipHack experience ChipHack is an occasional 2 day workshop introducing students and hobbyists to FPGA design. This year, ChipHack was sponsored by the BCS OSSG and Computer Conservation Society. To celebrate the 60th anniversary of the BCS, the workshop was extended by half a day and attempted to reimagine one of the earliest valve computers, EDSAC, designed by the BCS' founding president, Prof Sir Maurice Wilkes. * Mary Bennett led the team putting together the technical content of the workshop. She will report back on what was achieved, from the three implementations of the computer, to the diverse reimagining of the original peripherals. The result is a legacy of lectures and videos, to allow anyone to run their own ChipHack course. — The Interplay between Semantic Coupling and Co-Change of software classes During maintenance, developers must ensure that related entities are updated to be consistent with these changes. Studies in the static change impact analysis domain have identified that a combination of source code and lexical information outperforms using each one when adopted independently. The presentation has two aims: first, to compare the effectiveness of measuring semantic coupling of OO software classes using (i) simple identifier based techniques and (ii) the word corpora of the entire classes in a software system. Second, to empirically investigate the interplay between semantic and change coupling. * Dr Andrea Capiluppi joined the Department of Computer Science at Brunel University London (UK), as a Lecturer in Software Development in May2012. Between 2009 and 2012 he was at University of East London, working as a Senior Lecturer in Software Engineering. Before that, he worked as a Senior Lecturer and at University of Lincoln between 2006 and 2009. Andrea's research and teaching interests focus on Software Evolution and Maintenance, as well as the construction, evaluation and maintenance of Social Networks. Andrea is mostly interested in the use of open technologies and in understanding how they can improve learning and teaching as well as the production of software and other artefacts. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. // -- Andrew Back http://abopen.com

This will cover key concepts and LMS7002M FPRF IC architecture, and include simple digital radio examples along with a demonstrations of advanced systems, such as 4G femtocell. Details can be be found below. Regards, Andrew // OSHUG #56 — An introduction to software-defined radio with LimeSDR On the 24 March 2017, 09:00 - 17:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: https://events.bcs.org/book/2451/ A Software-Defined Radio (SDR) is a highly reconfigurable radio that can be used for many different radio applications through simply changing the software that links with it. An example of such a reconfigurable radio is the LimeSDR, which can both transmit and receive data and voice, using just about any wireless system. The LimeSDR was launched by Lime Microsystems in May 2016 via a crowdfunding campaign, and is now shipping to over 3,500 customers worldwide. It is based on the Lime Microsystems LMS7002M Field Programmable RF (FPRF) 2x2 MIMO transceiver, which continuously covers frequencies from 100kHz to 3.8GHz. The LMS7002M has been successfully used in a wide range of digital radio applications, including 2G/4G Femtocell base stations, GNSS, DAB, DVBT receivers and RF test and measurement equipment. The LimeSDR also includes an FPGA and USB 3.0 to provide host connectivity. — Workshop scope The heart of the day is to provide a practical ‘hands-on’ afternoon session using the LimeSDR with the Lime Suite GUI and FFT Viewer. Then to use GNU Octave and Pothos to make some very simple digital radio examples. To facilitate this, the morning will include introductory talks explaining the purpose of the various analogue and digital blocks included in the LMS7002M. It will also include tutorial material covering the key concepts required to understand modern digital radio transceivers, and how to use them, as well as practical issues associated with radio reception. In addition the day will feature some advanced demonstrations showing the full capabilities of the LimeSDR and its LMS7002M transceiver, including 4G Femtocell, as well as educational examples such as a simple OFDM transceiver data link. — Participant requirements ** Participants are required to bring a laptop computer with USB 3.0 ** Minimum computer hardware requirements are USB 3.0 capability and 2GB RAM. Although no prior knowledge of radio is required, an awareness of basic terminology will be very helpful. Basic computer programming and administration skills will also be helpful. The software that will be used must be installed prior to the event. For details see: https://wiki.myriadrf.org/LimeSDR_Workshop — What is provided * LimeSDR hardware will be provided for use during the workshop * A light lunch will be provided and please ensure that any dietary requirements are made clear during registration — Hosted by The workshop will be led by Dr. Danny Webster, who has over 25 years of experience in the field of RF design covering varied applications from military radio to cellular infrastructure.

OSHUG 55 — FPGA projects past, planned and possible, Thursday 16th February.
by Andrew Back 07 Feb '17

07 Feb '17

Hello, Registration is now open for the February meeting, details of which can be found below. We also still have space for 1 or 2 more short talks of 10-15 minutes, so if you have an idea for a talk, get in touch! regards, Andrew // Event #55 — FPGA projects past, planned and possible On the 16 February 2017, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/55 The fifty-fifth meeting will feature a series of shorter talks that explore past, planned and possible projects which use FPGAs. — FPGA Projects - What would I build and why would I want to PLAs have been interesting ever since the 70s when digital logic often became complex, consuming unnecessary space and power. Back then the cost of PLA deployment was high and it has continued to be high until recently. Now that we have powerful, low cost development platforms and relatively cheap FPGAs the cost equation has shifted radically. * Paul Tanner is a consultant, developer and maker in wood, metal, plastic, electronics and software. His day job is IT-based business improvement for SMEs. By night he turns energy nut, creating tools to optimise energy use. Paul graduated in electronics and was responsible for hardware and software product development and customer services in several product and service start-ups, switching to consulting in 2000. — Using FPGAs to solve realtime problems Microcontrollers a great platform to solve basic control problems in electronics, with simple motor drivers and sensors readily avaiable and easy to integrate. However, when the motor control becomes more complex with BLDC and FOC things get much more tricky. When you have to use multiple BLDC motors and more complex sensors with image processing the poor microcontroller quickly becomes to swamped to provide control in realtime. This is where adding FPGA technology makes a great deal of sense particularly in mutli-discipline projects like robotics where many sensors, motors and image processing will need to be managed and controlled concurrently. A robotics platform must therefore contain both concurrent hardware resources, algorithmic control through soft or hard cores along with communication protocols. * Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation and biotec diagnostics. His current research is focused on machine learning, inference and image processing for embedded applications using FPGA and multi-cores. He is a long term advocate and moderator (aka Folknology) for xCORE and other opensource communities, as well as a founder of Surrey and Hampshire Makerspace and myStorm FPGA development boards. — FPGAs in the Cloud? It is no secret that FPGA based computing machines are great at dealing with certain types of workloads that conventional CPU based machines can not efficiently handle. These machines, alongside their GPU and even custom ASIC based brethren, have been filling up racks in large data centres all over the globe helping speed up systems that have components of machine learning, complex analytics and even video processing. This short talk will have a look at the state of FPGAs in the datacenter and discuss the recent developments around the availability of FPGA equipped computing nodes in commodity cloud providers. * Omer Kilic is an Embedded Systems Engineer who enjoys working with small connected computers of all shapes and sizes. He works at the various intersections of hardware and software engineering practices, product development and manufacturing. — Chip Hack 2017 & EDSAC Challenge This talk will introduce and issue a call for participation for two events that are being hosted as part of the Wuthering Bytes technology festival, that will take place in Hebden Bridge in September, in the week following Open Source Hardware Camp 2017. Chip Hack is a two day hands-on workshop that provides a gentle introduction to programming FPGAs and is aimed at novices with no prior experience of Hardware Description Languages (HDLs) or FPGAs. This will be followed immediately by a challenge event, during which a small team of experts will work to extend a basic functional FPGA model of EDSAC — the pioneering computer designed and constructed at Cambridge University, and which was operational by 1949. * Dr Jeremy Bennett is founder and Chief Executive of Embecosm, a consultancy implementing open source compilers and chip simulators for major corporations around the world. He is a author of the standard textbook "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003). Contact him at: jeremy.bennett(a)embecosm.com.

Personal Privacy Online (The Dark Web, Investigatory Powers Act), Thursday 19th January.
by Andrew Back 14 Jan '17

14 Jan '17

Hello, There are no hardware talks this month, but there will be an excellent series of 3 talks hosted by the BCS OSSG next Thursday, on theme of personal privacy online. Details below. Regards, Andrew // Personal Privacy Online (The Dark Web, Investigatory Powers Act) On the 19 January 2017, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: https://events.bcs.org/book/2408/ We explore the theme of personal rights and privacy on the modern Internet, with a talk on The Dark Web, covering insights on one of the larger anonymous marketplaces online and another on the new Investigatory Powers Act. — The Investigatory Powers Act: What is it? The Investigatory Powers Act also known as the Snoopers Charter is now law, find out what that means for you and your company. The Snoopers Charter would require metadata on every email, website visit and social media log to be recorded. It covers hacking and mass hacking performed by Government agencies. Its powers can be enforced across the world. It contains over 270 clauses and dwarfs the computer misuse act in terms of size, so this is going to be a speed run covering some of the high points. * Glyn Wintle is a security evangelist and software engineer. He has given evidence in Parliament, frequently gives technical talks about security and is well know for his work with the Open Rights Group. — The Dark Web Within the last years, governmental bodies have been futilely trying to fight against dark web hosted marketplaces. Shortly after the closing of “The Silk Road” by the FBI and Europol in 2013, new successors have been established. Through the combination of cryptocurrencies and nonstandard communication protocols and tools, agents can anonymously trade in a marketplace for illegal items without leaving any record. This talk will presents a research carried out to gain insights on the products and services sold within one of the larger marketplaces for drugs, fake ids and weapons on the Internet, Agora, and on new developments after the demise of Agora. The team behind the research included Andres Baravalle, Sin Wee Lee, Germans Zaharovs (research intern) and Mauro Lopez Sanchez (final year project). The work has been featured on the front page on The Times and on the Guardian, amongst other media. * Andres Baravalle works in the in the University of East London as Senior Lecturer in Computing.

OSHUG #54 — Educating the Next Generation, Thursday 1st December.
by Andrew Back 01 Nov '16

01 Nov '16

Hello, Details below of the final OSHUG meeting of 2016, which will take place on the evening of Thursday 1st December, following on from the workshop earlier that day. Don't forget that if you plan to take part in the workshop and attend the evening meeting, that you need to register for both separately. Cheers, Andrew // On the 1 December 2016, 18:00 - 20:00 at CSC, 3rd Floor, The Wallbrook Building, 25 Wallbrook, London, EC4N 8AQ. Registration: http://oshug.org/event/54 At the fifty-fourth meeting there will be three talks on the theme of educating the next generation. — myStorm update myStorm is an open hardware and software FPGA development platform that is based around a Lattice iCE40 FPGA, which uses the fully open source IceStorm/Yosys/Arache-pnr toolchain for development. It is low cost and aims to provide a gentle on-ramp for those who are new to RTL development and working with FPGAs. In this talk we will hear a report from the workshop which took place earlier in the day, together with a status update on the myStorm project. * Ken Boak started his professional career at BBC Research Department in 1986 working on digital signal processing systems for HDTV and subsequently over 30 years, a mix of 10 other technology companies, both UK and US based, in the fields of instrumentation, automation, telemetry telecomms. Ken has been interested in energy monitoring since the early 1990s, when he constructed a 4 seater electric car, and provided rudimentary energy analysis of the battery charge and discharge cycles. In 1998 he joined a South London company and designed a low power wireless, monitor device for automatic, remote gas and electricity meter reading. In 2009 Ken worked on the Onzo Energy Monitoring Kit, a commercial device that was ultimately distributed to Southern Electric customers. Then in 2010 he produced a series of educational devices to teach engineering undergraduates the principles of photovoltaic energy systems. Ken has continued his interests in energy monitoring, working collaboratively with Megni on the OpenEnergyMonitor project, the open Inverter Project and also for All Power Labs in Berkeley, California, where he was involved in power monitoring of wood gasifier generator sets. He tries to live a low impact lifestyle in a modest Edwardian house in Surrey, with a little help from modern electronics. * Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation and biotec diagnostics. His current research is focused on machine learning for embedded applications using Motes on FPGA and emerging Asics. He is a long term advocate and moderator (aka Folknology) for xCORE and other opensource communities, as well as a founder of Surrey and Hampshire Makerspace. — micro:bit first impressions The BBC micro:bit is an ARM Microcontroller based development board that has been handed out to all year 7 (first year secondary) school kids. The BBC's aim is to get kids coding, along the same lines as with the BBC Micro that became ubiquitous in schools in the 80s. This presentation will look at what it can (and can't) do, and how accessible it is. * Chris Swan has been tinkering with electronics since he was a small child, and got into software when he realised that it was necessary to make hardware do interesting things. In his day job as CTO for Global Infrastructure Services for CSC he's bringing a large services company and its customers into a world of DevOps and Infrastructure as Code. On evenings and weekends he can often be found making some sort of project around a dev board, with a particular fondness for Raspberry Pis. — Encouraging the next generation: How a 16-year old got to present his silicon chip design at CERN In 2014 a local Year 10 student, Dan Gorringe, approached Embecosm to ask it he could do a 2-week work experience with us. We agreed and asked him to take our existing hobbyist weekend course on introductory FPGA design with Verilog and rework it for use by students of his age. We forgot to tell him teenagers aren't supposed to be able to write Verilog, and the result was the Embecosm Application Note, Silicon Chip Design for Teenagers. In 2015, Dan asked to work for us over the summer. We had recently designed an instruction set architecture, AAP, which is a 16-bit mixed byte/word addressed Harvard architecture to test compiler technology, and which worked in simulation. We realized that a physical implementation would be very useful, so we asked Dan to create this over the summer. We forgot to tell him that teenagers aren't supposed to be able to design processors and the result was an implementation of AAP which runs on a DE0-Nano FPGA board. As a result Dan was asked to present his work at ORCONF 2015, which happened to be held at CERN. Probably one of the better excuses for a day off school. Dan also subsequently won the BCS OSSG School Student competition for his work, which he spoke about at the BCS AGM in October 2016. Dan came to work for us this summer, and since we are currently working on energy efficient compilation for high performance computing we asked him to build us a system out of single board computers. We again forgot to tell him that teenagers aren't supposed to be able to design supercomputers. We demonstrated his system at the BCS OSSG AGM, and it is reported in the HiPEAC newsletter of November 2016 for academic researchers in high performance and energy efficient computing in Europe. Dan is taking his 'A' levels next summer and is hoping to attend university next year to study engineering mathematics. In this talk we'll look at the factors that made such a series of projects both possible and successful. * Dr Jeremy Bennett is founder and Chief Executive of Embecosm, a consultancy implementing open source compilers and chip simulators for major corporations around the world. He is a author of the standard textbook "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003). Contact him at: jeremy.bennett(a)embecosm.com.
