Chinese chip maker SophGo is developing a RISC-V chip based on designs from the U.S. company SiFive, which highlights challenges the U.S. government may face in regulating open architecture. Sophgo […]
The headline is of course confused. The 64 core chips (SG2042, SG2044) use Chinese-developed THead cores. Only the 16 core chip (SG2380) is using SiFive cores.
RISC-V extensions have compatibility issues, and the company had to develop a new chip to accommodate the final vector extensions, Liuxi told HPCwire.
Liuxi should be more accurate. RVV 0.7 is a draft version with absolutely zero expectation that it will be compatible with the 1.0 version. Freedom to make radical and incompatible changes from draft to draft is the whole point of having draft versions.
