The working draft specification for the RISC-V V vector extension, written in AsciiDoc. It defines the vector instruction set architecture that toolchains, simulators, and hardware implementations are built against.
Use cases
- implement the RISC-V vector extension in a simulator
- add RVV instruction support to a compiler toolchain
- learn how RISC-V vector instructions work
- check the ratified vector ISA spec details
- write assembly using RISC-V vector instructions
When to choose
- you are developing RISC-V hardware, simulators, or toolchains needing the authoritative vector extension spec
- you want to understand or teach the RISC-V V extension ISA
When to avoid
- you need a runnable simulator or toolchain rather than a specification document
- you need a finalized ratified standard with guaranteed stability beyond v1.0
