WebNov 8, 2024 · This is where the advantage of RISC-V really shines. Arm added the Thumb2 compressed instruction format later and fitted these 16-bit instructions into the existing ISA by adding a separate 16-bit ISA. The RISC-V ISA, however, was designed from the start with an option for compressed instructions and so has only one ISA. WebAug 13, 2024 · In RISC-V, compressed instructions are aliases for full 32 bit instructions, rather than a separate set of instructions, and there is a one to one mapping between 16-bit compressed instructions and 32 bit instructions.
