RISC-V IME set Specification

Introduction

This is a matrix extension proposal under the RISC-V IME extension standard. It has the following features.

  • Low lost
    • Reuse the vector registers and the related CSRs.
  • Compatibility
    • Support VLEN of vector registers from 128 bit to 4096 bit
    • Almost binary portability
  • Rich data types
    • Integer int4/int8/int16
    • float fp4/fp8/fp16/bf16
