This isn't completely on-topic for this list, but I figured I'd ask here since many of you do FPGA development on a daily basis -- some with MIPS processor cores, or other embedded CPUs. This semester at university, I'm in a group working to produce a FPGA-based device -- likely some NTP-synced alarm clock that scrolls reminder messages. We've been looking around on OpenCores.org, and noticed the Plasma[1] MIPS-1 processor core. We're also looking at JOP[2] and OpenRISC[3], but I'm liking the look of the Plasma core, since I'm already familiar with MIPS machines[4]. We've got use of a NIOS-2 Development kit[5], which is based on an Altera Cyclone-II FPGA. It's hoped we can just load another processor core instead of the NIOS-2 softcore to drive the whole kit... Or would we be better served getting another development board? (Or just using the NIOS-2 softcore?) Just wondering what peoples' experiences have been using this processor core with Linux and/or =B5Clinux? Are there other processor cores I coul= d load onto a FPGA that people would recommend? --=20 Stuart Longland (aka Redhatter) .'''.
