8/27/2019 · RISC-V is a federation of ISA extensions — from the baseline rv {32|64|128}I, to an arbitrary combination of a handful of extensions. There are combinations which are dubbed ‘application-processor level’ (the G subset), but implementations can and often.
RISC-V ISA (Instruction Set Architecture) is designed in a modular way. It means that the ISA has several groups of instructions (ISA extensions) that can be enabled or disabled as needed. This allows implementing precisely the instruction groups that the application needs, without having to pay for area or power that will not be used.

26.2 RISC-V Extension Design Philosophy We intend to support a large number of independently developed extensions by encouraging extension developers to operate within instruction encoding spaces, and by providing tools to pack these into a standard-compatible global encoding by.
RISC-V: an Open Instruction Set Architecture, The RISC-V Architecture – DZone Open Source, RISC-V: an Open Instruction Set Architecture, RISC-V – Wikipedia, 6/5/2020 · RISC-V is a completely open source specification for a reduced instruction set processor. A complete user-mode (non-privileged) instruction set specification has been released and several…
12/19/2020 · Instead of having a large fixed instruction-set, RISC -V is designed around the idea of extensions . Every coprocessor will be different. It will thus contain a RISC -V processor to manage things which implements the core instruction-set as well as an extension instruction-set tailor made for what that co-processor needs to do.
RISC -V is intended to maintain constancy in the base and each standard extension over time. Changes can be made by layering new instructions as optional extensions . The base integer ISAs will continue to be fully supported as standalone ISAs, regardless of any subsequent extensions .
