RISC-V: The Free and Open RISC Instruction Set Architecture RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. Born in academia and research, RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of. The RISC-V Instruction Set Manual Volume I: User-Level ISA Draft - for comment only. Version 2:0 10 4 Andrew Waterman, Yunsup Lee, David Patterson, Krste Asanovi c CS Division, EECS Department, University of California, Berkeley fwaterman yunsup pattrsn krsteg@eecs.berkeley.edu September 3, 2013. I am referring to the tables in Chapter 9 'RV32/64G Instruction Set Listings' in 'Risc-V Instruction Set Manual/Volume I: User-Level ISA Version 2.1' where the intent is to list each opcode only once: RV32I Base Instruction Set 0000000 shamt rs1 001 rd 0010011 SLLI 0000000 shamt rs1 101 rd 0010011 SRLI 0100000 shamt rs1 101 rd 0010011 SRAI.

A larger number of integer registers also helps performance on high-performance code, where there can be extensive use of loop unrolling, software pipelining, and cache tiling. Oct 08, 2018 The RISC-V QEMU port supports the following instruction set extensions: RV32GC with Supervisor-mode and User-mode (RV32IMAFDCSU) RV64GC with Supervisor-mode and User-mode (RV64IMAFDCSU).
