Abstract
PURPOSE:To detect deteriorated performance caused by prescribed phenomena, by reporting to the software, when the difference in the value of two counter circuits becomes higher than a prescribed value. CONSTITUTION:Counter circuits 1 and 2 are counted in the same way unless there is an i-bit error of a control memory. Moreover, when the circuit totally becomes ''1'', both circuits 1 and 2 are reset. When an 1-bit error of the control memory is detected under this condition, the execution of a micro instruction is stopped for one machine cycle and the 1-bit error is corrected while the micro instruction is stopped, and, at the same time, an execution indicate signal 12 becomes ''0''. Then, the circuit 1 is counted and the circuit 2 is not counted. In such a way, if the difference between counted values of the circuits 1 and 2 becomes larger than 1/2 when the circuit 1 totally becomes ''1'', a performance deterioration detecting circuit 3 detects the difference and sets a performance deterioration indicating signal 15 to ''1'', then, reports this matter to the software.
