Abstract

An information processing device for executing a compressed program includes: an instruction buffer; a first selector for selectively outputting one of a set of signals obtained by dividing the output from the instruction buffer; an instruction decompression section for decompressing the output from the first selector into an original instruction; a second selector for outputting the output from the instruction buffer when no compressed instruction is stored in the instruction buffer and outputting the output from the instruction decompression section otherwise; an instruction decoding section for outputting a signal indicating presence/absence of instruction branching based on a result of decoding the output from the selector; and a control section for instructing the first selector to select a predetermined one of the received signals when the signal from the instruction decoding section indicates that there is instruction branching.
