Details in a recent talk:
VROOM! A NEW HIGH-END RISC-V IMPLEMENTATION
- Goal: Very high end RISC-V implementation – cloud server class
- Out of order, super scalar, speculative
- RV64-IMAFDCHB(V)
- Up to 8 IPC (instructions per clock) peak, goal ~4 average on ALU heavy work
- 2-way simultaneous multithreading capable
- Multi-core
- Currently boots Linux on an AWS-FPGA instance
- Early (low) dhrystone numbers: ~2 DMips/MHz - still a work in progress. Goal ~5 with fully working BTC
- GPL3 – dual licensing possible
