Hello all,
We are looking for CISC(x86) and RISC uP cores to be used in university research projects. We can also pay licensing fees upto a certain amount (which is of course not a significant amount).
We should be able to implement this core in an FPGA(pref. Xilinx) with the availability of popular i/f (USB/JTAG/etc) and then use some popular tool-chains.
Main target is to do some RTL level h/w changes and then work on tweaking the instruction set and work @compiler level.
What options are out there OTHER THAN the ones @OpenCores, Leon3 SPARC dev platform and the one through the ARM Uni Program (ARM Cortex-M0 DesignStart Processor)?
Please share your comments, suggestions and experiences.
Thanks.
