Hi Krste and Andrew, What is the rough plan for rvv v1.0 release? I searched vector-ext mailing list but can’t find the info I want. Thanks Weiwei

I think we'll be spending a chunk of time on mask layout and implementation issues. See you then, Krste

This is issue #601. It was pointed out that *e7 (estimate to 7 bits) suffix on mnemonic is easily confused with e32 (element size 32) on other mnemonics. This is probably one we can handle on email th

In support of Open Source Software and publicly released modeling schemes, does the Vector Task Group have a recommendation for arithmetic reference? The published ISSs can provide checking results fr

Also on github as issue #595 In our earlier TG discussion in 9/18 meeting, we were in favor of allowing vector strided load instructions with rs1=x0 to perform fewer memory accesses than the number of

I've been thinking through the cases where a wide implementation that wants "slices" could have to introduce a hiccup to rearrange bytes because of an EEW change (since SLEN is gone). The ones I know

We'll meet per the calendar entry. Agenda is to go over any remaining unsettled open issues, Krste

Thanks Tim, I think that sums it up nicely. I just wanted to put a pointer out to the original post that I made on isa-dev regarding opcode sharing / management: https://groups.google.com/a/groups.ris

I am now investigating how to efficiently implement sparse matrix X (dense) vector multiplications (spMV) using RISCV vectors using bit-vector format of compressing the sparse matrix. The inner loop o

These are all important considerations. However, what they have in common when considering Allen's question: is that they are all tactical considerations are in the context of our current framework of

I'm working through updates to vector spec, and one part of clean up is changing text where it has mandatory raising of illegal instruction exceptions on unsupported encodings to instead state the enc

Forwarding this to tech-vector-ext; couple comments below. Indeed, I've found other microarchitectural reasons to favor this approach (e.g., speculating through mask-register values). Enumerating all

Hi, what is a reasonable sequence to insert an element into an arbitrary position in the vector? I considered the following sequence (assume the input vector is v12) vid.v v1 vmseq.vx v0, v1, <index>
