PROBLEM TO BE SOLVED: To accurately evaluate the degree of influence of memory access on processor calculation performance.SOLUTION: In a time information acquiring step, a time information acquisition unit detects start of access to a target memory by a memory access unit in response to a command from a command issuance unit and end of this access, and acquires time from the start to the end of this access as memory access time on the basis of this detection. In a calculation amount acquiring step, a calculation amount acquisition unit calculates an amount of calculation executed by a calculation unit in response to a command from the command issuance unit from the start of the access to the target memory by the memory access unit to the end of this access. In an evaluating step, an evaluation unit evaluates a calculation performance of the calculation unit from the start to the end of this access on the basis of this memory access time and this calculation amount. |
