The article doesn't write about mixed precision machine learning. Will it be available? I would really love to see a RISC-V laptop using vector extensions beating the Apple M1 core in everything (though I know that it will take a lot of time to get to 5nm process node).
- ece 6y agoIt mentions support for INT8 for ML/AI. FP16 and BF16 support isn't explicitly mentioned, but it does support 8/16/32-bit fixed/float scalars and vectors, so it could be added later.
- xiphias2 6y agoSo the answer is no :( Anyways I expect RISC-V to appear in Chinese mobile phones before laptops as the main unit. It would be fun to run Android on this RV64X architecture....I guess that's the goal.
- ece 6y agoI think a FP16 or BF16 ALU could be added sooner rather than later, but getting something equivalent to the performance of say a Nvidia 1050 or 1080 (first consumer cards to have FP16 and INT8 from Nvidia I think) would take a couple of iterations.. Cheap phones running Android would be a great start for RV64/RV64X though.
- girvo 6y agoI wonder what company would put in the hundreds of millions to design a RISC-V processor on 5nm? I’m not being facetious — I wonder if there will be a future where we see that! It would be super exciting.
- samus 6y agoChinese companies will take that step for sure once China manages to bring domestic advanced nodes into production. It doesn't make sense to have domestic semiconductor and then use a proprietary ISA like ARM or x86(_64) again.
