Abstract

PURPOSE:To prevent increase in the CPU load ratio owing to occupation of external storage device and a program itself in advance of its occurrence and to increase the number of times of measurement, if necessary, by measuring and always displaying the ratio of operation of various components including a CPU with hardware. CONSTITUTION:A clock signal CL which synchronized a CPU mode status signal MS arriving from a CPU with operation of the system are accepted by the input gate 2 of the main body of a measuring unit 1, when the signal MS in the CPU mode of logic 1, the gate 2 is open and counting is carried out by a CPU mode status counter 3. On the other hand, a clock counter 4 and the value of counters 3 and 4 are divided by a divider 5, and its output is added to a transfer gate 7. Also, the output of a setter for time limit 10 mounted on a control panel is counted by a time limit set counter 11, with a comparator 6, the values of counters 4 and 11 are compared, the gate 7 is opened with a coincidence signal CON, through a buffer register 8, working ratio is displayed on the ratio of operation of counter 9, and counters 3, and 4 are cleared with the output of a delay circuit 12.
