That code seems to be for an FPGA devkit for their SoC but using an entirely different CPU core, the Berkeley Rocket Chip.
They're selling coreplex licenses for several hundred thousand dollars (not the one in the linked product page, it isn't for sale yet): https://dev.sifive.com/coreplex-risc-v-ip/buy/rtl/e51_coreplex/configure/ https://dev.sifive.com/coreplex-risc-v-ip/buy/rtl/e51_corepl...
- monocasa 9y agoSiFive is a bunch of Berkeley people. Are you totally sure that their cores aren't rebranded Rocket cores?
- _chris_ 9y ago> using an entirely different CPU core, the Berkeley Rocket Chip Nope, the U54 and E31 are both Rocket, just with different parameters/configurations. SiFive has continued to improve Rocket and contribute their improvements back to the available source code.
