A guide to accelerating applications with just-right RISC-V custom instructions

Recently Embedded Magazine published a very interesting article with some insights on extending a RISC-V processor with custom instructions


The open instruction set architecture (ISA) of RISC-V permits broad flexibility in implementation and offers optional features that can enable fresh approaches to resolving hardware-software design tradeoffs. Based on a modular structure, a number of standard extensions and options can be used to configure the base processor as a starting point. Yet the true value actually lies in the opportunities that RISC-V offers developers to create new extensions, instructions and configurations that uniquely meet the needs of their innovative application ideas …
