Patent ID: 7975261

Claim:
A task transition chart display method which is one for displaying a task transition chart of a multi-core processor, comprising: obtaining internal trace information of a plurality of core processors within the multi-core processor and performance information corresponding to the trace information both from memory; displaying task transition states of individual core processors simultaneously on the basis of the trace information and also displaying performance information superimposed on the task transition chart by correlating each of a start clock time and an end clock time of a task indicated by the trace information to a number of clock cycles indicated by the performance information; and temporally synchronizing a plurality of task transition charts of the core processors, each task transition chart indicating a state of a task transition in each core processor, by shifting a first system time of a first core processor among the core processors by a difference between the first system time and a second system time of a second core processor among the core processors when there is a difference between the first and second system times.
