Dec 13, 2018 · RISC-V calling convention and five optional extensions: 8 RV32M; 11 RV32A; 34 floating-point instructions each for 32- and 64-bit data (RV32F, RV32D); and 53 RV32V.

RISC-V is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. It is a simple, clean, and efficient assembly language. Assembly language is a human readable (mostly) form of …

Feb 7, 2022 · CS 61C has used the RISC-V reference card (“green card”) from Patterson and Hennessy’s RISC-V textbook ever since we switched from MIPS to RISC-V assembly in 2017. This semester, we’ve decided to make our own reference card from …

RISC-V Reference Card V0.3 Base format: Inst rd, rs1, rs2 (rd: destination register, rs1, rs2 source registers). Other formats: Inst rs1, rs2 Inst rs1, immediate RV32I Base Integer Instructions Inst Name Description (C) add ADD rd = rs1 + rs2 sub SUB rd = rs1 - rs2 xor XOR rd = rs1 ˆ rs2 or OR rd = rs1 | rs2 and AND rd = rs1 & rs2

In RISC tradition, the assembly reference for MIPS and RISC-V fits onto a single double-sided 'Green Sheet'. When I took CS 61C at UC Berkeley in 2017, we were the first semester taught using RISC-V, and our reference card scans from our RISC-V textbook were low-quality.
