RISC-V profiles – why is RVA23 significant? (opens in new tab)

Introduction One of the important offerings of the RISC-V Instruction Set Architecture (ISA) is the ability to customize and extend the base instruction set. An initial reaction to hearing this is often to worry about software portability and compatibility, since if every RISC-V CPU offers a slightly different set of instructions, software won’t be portable. This risk is that customization becomes fragmentation, which is why RISC-V offers sets of standardized extensions to help with software ...
