Hi, Re-reading section 3.3.2 in the documentation (link), would like to propose adding goal, constraints, steps for implementing Fraction LMUL I think adding these would really help clarify both the V

Hi Mick, The vector 0.7.1 version has been implemented in T-Head Xuantie c910v CPU and AllWinner D1 Soc. If that's what you want or If you want to use the QEMU upstream currently, I can give you some

I see that section 7.5 of the vector spec currently says: When rs2=x0, then an implementation is allowed, but not required, to perform fewer memory operations than the number of active elements, and m

Hi, The way 18.1 and 18.2 currently read in the V spec is a bit confusing. It defines Zve as "Vector extensions for Embedded Processors", and V as a "Vector Extension for Application Processor". 1) Pr

Based on feedback, we'll have a vector TG meeting tomorrow to address concerns. Details in usual place in Google calendar, Krste

Hi everyone, Are there any plans for a cut-down configuration of the vector extension suitable for embedded cores? It seems that the 32x128-bit register file is suitable for application class cores bu

There have been no substantial objections raised on the v1.0-rc1 draft, so I will cancel the meeting tomorrow. There are some minor suggestions and edits (thank you!), and I will incorporate these int

Unless there are significant issues raised by the group on the v1.0-rc1 spec, the intent is to go into public review on June 25th, so please make sure to give any feedback before then. There are a few

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

Andrew Waterman called Thursday and we discussed many issues including challenges with Issues in Github. We determined that both were unaware of some relevant aspects [neither of us intentionally blin

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

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

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

Hi, Krste: The RISC-V V TG have the plan to support a lowcost vector extension in RVMxx profile? Best Regards Shaofei 2021.6.3 -----邮件原件----- 发件人: krste@... [mailto:krste@...] 发送时间: 2021年6月3日 2:13 收件人

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
