I encourage you to use OpenCores, and particularly the OpenRISC processor core, which is well supported. I suggest you follow Sven-?ke Andersson's blog, which is a comprehensive guide to building OpenRISC for complete newbies from a very experienced engineer. http://www.rte.se/blog/blogg-modesty-corex/openrisc-1200-soft-processor.
Thank you for the link!
You are pushing your luck on the specs. You'll be hard pressed to get 800MHz on anything purely in FPGA, particularly low-end FPGA's. I think you can get around 100MHz with the latest OpenRISC implementations.
Will the platform based on OpenRISC be suitable for a Linux system with DirectFB and a video framework e.g. GStreamer?
As far as I'm aware not all the IPs you want have open source implementations, but that is a better question to ask on the OpenCores mailing list.
Thanks for the suggestion. I will ping the community there.
If you want more, you'll need to look at using a proprietary processor on something like a ZedBoard (Xilinx FGPA alongside a dual-core 660MHz ARM). But then you are looking at ?300, and much more restricted open source support on the hardware side.
The OpenRISC community portal is at http://opencores.org/or1k/OR1K:Community_portal, and there is an active IRC group on channel #openrisc at freenode.net.
It is possible to run OpenRISC on a DE0-nano, which is just under ?60. However something a little larger will give you more flexibility - there are boards for around ?150 that are suitable.
We'll be showing how to bring up an OpenRISC SoC on a DE0-nano at Chip Hack (www.chiphack.org). That's now full, but it will be videoed, so you'll be able to see it online (on the Embecosm YouTube channel) in late April.
I will be eagerly waiting for the videos once the actual event is finished on the 21st of April.
Thank you once again for your help.
Warm regards,

Best wishes,
Jeremy
