Instruction trace generation method instruction trace generation programs, and instruction trace generator

摘要

PROBLEM TO BE SOLVED: To generate an accurate instruction-trace even when frequency to collect an instruction is decreased for reducing overhead.;SOLUTION: A dividing unit 112 divides sampling data 121 obtained by sampling instructions to be executed by a processor at predetermined intervals into partial instruction strings 122 in units obtained while the acquisition object instruction string of an instruction-trace is executed once. Then, the partial instruction strings 122 are combined into one based on the similarity and likelihood under the control of a combination control unit 113, and output by an instruction trace output unit 114.;COPYRIGHT: (C)2010,JPO&INPIT
