PURPOSE:To ensure the correction of the performance control error, the improvement of reproducibility and the suppression of variance of the instruction executing time, by stopping a counting action of a computer with an interlock signal. CONSTITUTION:The performance of a computer is controlled in a computer system where a pipeline is controlled by a microprogram. In this case, a correcting counter IPC13 is added when an interlock signal is energized. Thus the performance errors produced with misshits are counted by the counter IPC13 with the interlock signal. Then the counting action of a main performance control counter 11 is stopped for a period of time equal to a corrected extent after the end of a memory access. |
