Dear Craig and Roger, Thanks a lot for providing me goodsolution. I have tried them, they are all good solutions of upsample application. But, when it comes to other applications, such as zip/u

Hi, all I encountered a difficulty of applying "vrgather" instruction recently. The details are shown blow: The date from source should be duplicated as pair in a upsample application. Eg: src = [0, 1

RISC-V Vector Spec version 1.0-rc1-20210608
I've just tagged the first release candidate for v1.0 of the vector spec in github. PDF attached below. I've included the TG agreed updates and handled almost all of the outstanding issues for v1.0. T

Smaller embedded version of the Vector extension
This is a good question. So if the RVM22 profile requires VLEN=32, ELEN=64, LMUL=8 then the vector registers will have the same amount of state as ARM MVE. Tariq

Check mask all ones / all zeros
9 messages
Hi all, I could not find any instruction that immediately computes this. Apologies if I missed the obvious here. Two options came to mind: vpopc.m and check whether the result is 0 (all zeros) or VLMA
