ARITHMETIC PROCESSING UNIT, COMMAND COMPRESSION METHOD, AND COMMAND COMPRESSION PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce a chip area and a power consumption by applying a small-size command code.SOLUTION: An arithmetic processing device 1 processes a command having a plurality of slots, and each slot stores an operation and data including compression/non-compression information of the operation. The arithmetic processing device includes a decode unit 101, when the compression/non-compression information of the first operation stored in a first slot of a first command represents "compression", referring to an operation of a second slot in a second command being previous to the first command, according to compressed data of the first operation and synthesizing the fist operation.
