ABSTRACT:
In a performance analyzing apparatus, a setting unit sets an event of which the performance is desired to be monitored, a detecting unit detects an instruction address at the time of generation of an interrupt signal from a timer, and a calculating unit calculates a variation amount of a counted value by a hardware counter at a detected instruction address. The variation amount is accumulatively retained for each detected instruction address. A specifying unit specifies an instruction address that corresponds to the event, and a display unit displays a graph of the total variation amounts.
