inst.eecs.berkeley.eduRISC-V Feature, n×16-bit instructions • Extensions to RISC-V base ISA support 16-bit compressed instructions and also variable-length instructions that are multiples of 16-bits in length • 16-bit = half-word • To enable this, RISC-V scales the branch offset to be half-words even when there are no 16-bit instructions
