RISC-V was a young, purely academic project in 2011. The pivot to industry came in 2015. This was followed by announcements by companies that they were shifting to RISC-V, but g…

It makes sense for the Chinese to make Loongson be performant, its an ISA they fully control and only have to do with domestic Loongson standard body politics instead of having…

These implement 16-register cut down RISC-V RV32EC_Zmmul instruction set. It's an interesting choice. I wonder if they can run Coremark or Dhrystone so one can get an impression…

RISC-V is a free and open standard instruction set architecture (ISA) for computer CPUs. It is based on reduced instruction set computer (RISC) principles. Unlike proprietary ISAs such as x86 and ARM, RISC-V is described as "free and open" because its specifications are released under permissive open-source licenses and can be implemented without paying royalties.
