Is this project still relevant with the advent of RISC-V? Can't the Chinese focus their efforts on RISC-V instead? Is there some reason Loongson is still being actively developed?
- dragonelite 4y agoThey are putting a lot of focus on RISC-V especially Alibaba T-head design studio. If i'm not mistaken Loongson's has instructions in it to emulate RISC-V faster.
- rbanffy 4y agoI read somewhere that RISC-V is very MIPS-inspired. If that's the case, it'd make a lot of sense to share instructions or facilitate emulation.
- mytailorisrich 4y agoAs it happens China is a big country with many independent companies in this industry. Some work on Risc-V, Loongson seems to do its own thing, though it is related.
- clamchowder 4y agoFeels like a shotgun approach. They have x86-64 (Zhaoxin), RISC-V (Xiangshan, Alibaba), MIPS -> Loongarch (Loongson), and aarch64 (Phytium). My guess is the central government is trying to build domestic chips by throwing piles of money at anyone who says they can make one. Result: a pile of different architectures running different instruction sets, none of which come close to being a high performance design.
