This repository contains the source files for the RISC-V Instruction Set Manual, which consists of the Privileged RISC-V Instruction Set Manual (LaTeX) and the Unprivileged RISC-V Instruction Set Manual (AsciiDoc). The preface of each document indicates the version of each standard that has been...
原文:The RISC-V Instruction Set Manual Volume I: Unprivileged ISA Chapter 1 (Document Version 20191214-draft) November 19, 2021 虽然是翻译但其实本质上还是个人笔记... 所以一切请以最新的官方标准文档为准。其实之前也有大佬翻译过,但是后来版本更新了,所以我想在加深理解RISC-V spec的同时顺便翻译翻译～ ...
This chapter describes the current proposal for the RISC-V standard compressed instruction-set extension, named “C”, which reduces static and dynamic code size by adding short 16-bit instruction encodings for common operations. The C extension can be added to any of the base ISAs (RV32, RV...

When an extension’s status is set to Off, any instruction that attempts to read or write the corresponding state will cause an illegal instruction exception. When the status is Initial, the corresponding state should have an initial constant value. When the status is Clean, the corresponding st...

RISC-V Instruction Set Manual - RISC-V International (https://riscv.org/technical/specifications/) 寄存器的数学/逻辑运算指令 按R-Type结构进行编码,其指令操作码均为七位二进位数的(0110011),按funct3判断数据的运算类型。 以算朮加法ADD为例,其funct3为三位二进制的000,操作内容为从地址rs1及rs2对应的...
浮点扩展规格说明在《The RISC-V Instruction Set Manual Volume I: Unprivileged ISA》的Chapter 11和Chapter 12。 1.4.1 浮点寄存器 如果包含F(单精度浮点)或D(双精度浮点)扩展,则还有32个独立的浮点寄存器(f0-f31)。 F扩展每个寄存器32位,D扩展每个寄存器64位。
RISC-V (pronounced risk-five) is a new instruction set architecture (ISA) that was originally designed to support computer architecture research and education, but which we now hope will become a standard open architecture for industry implementations. The RISC-V manual is structured in two ...
