I did some benchmarking on a single 64 bit dual-issue U74 core with FPU, caches etc running in an Arty-100T. Just a single core, not all five cores as in U74-MC (HiFive Unmatched, VisionFive 2 etc), but it was running Linux.
- d_tr 3y agoOut of curiosity, how much of that FPGA did that configuration occupy?
- OhMeadhbh 3y agoMy memory is the E31 (RV32) used about 70% of the ARTIX-7 35T. Bruce probably remembers the stats on the U74 (RV64) better than I do. People kept stealing the ARTIX-7 100's off my desk so I never had the opportunity to play around with them.
