I have seen PIC compatible IP cores for FPGA's. I'm not sure if they're in Verilog or VHDL. Also, 8051 cores, but again not sure if in Verilog or VHDL.

It should be as simple as possible and preferably written in Verilog. I looked at Picoblaze and it's pretty good other than a poorly written/unmaintained assembler (there are clones, but still kind of a pain in the ass). Also, it runs from a hard coded Verilog ROM which is okay, but: Just wondering if there are any simpler or equally as simple soft CPUs out there? Microblaze is overkill for what I need. But something that can run from flash instead of hard coded ROM is always good, since I can very easil= y program the on board flash. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
