Blt risc v. Risc v feature n16 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. A high quality license free royalty free risc isa specification originally designed at uc berkeley standard maintained by the non profit risc v foundation suitable for all types of computing system from microcontrollers to supercomputers numerous proprietary and open source cores experiencing rapid uptake in industry and academia supported by a growing shared software ecosystem a work in progress. All risc v processors must implement the base integer instruction set known under the acronym rv32i.
