摘要

PROBLEM TO BE SOLVED: To improve the efficiency of reuse of values by shortening the bit length of data to be kept in a memory storing an execution result when reusing the values (Memoization). SOLUTION: A reuse-instruction determination unit 120 analyzes the use modes of a plurality of instruction sections in a program, and determines reuse sections in which the execution result is used again from among the instruction sections. A hash function determination unit 200 determines a section identification value generating function from candidate functions that are candidates of section identification value generating function, the generating function generating a section-identification value identifying a reuse section by a value of a bit width narrower than the bit width of the starting address of the reuse section. A machine-word program generation unit 140 generates a machine-word program embedding the section identification value generating function determined by the hash function determination unit 200.
