- hajile 5y agoThat was just MIPS without paying licensing fees. MIPS has lost most support and I doubt China wants to foot the bill for maintaining everything. RISC-V allows them to offload most of the hard software parts to other countries.
- userbinator 5y ago...and RISC-V is almost a clone of MIPS anyway, so no surprise there.
- hajile 5y agoIn what way is RISC-V a clone of MIPS? There are VERY different ideas most notably using variable-length instructions rather than one instruction width (begging the question of whether RISC-V is actually RISC).
- snvzz 5y agoAn argument could be made that the instructions look similar. Very RISC. Their encoding is completely different, and that's what matters.
- pabs3 5y agoNo, they are even working on upstreaming support for LoongArch and getting distros to support it.
