Abstract

PURPOSE:To detect the load of the computer accurately, by checking the output of the control register which holds the executing task number and the output of the status register which holds the run state of the central processing device. CONSTITUTION:When some task is being executed in the multitask processor, central processing device 2 is in the ''run'' state, and the output of status register 22 is ''1''. When any task is not executed, the output of status register 22 is ''0''. At every task switching, the task number is written into control register 21. The ''run'' state of the computer and the executing task number are operated by the microprocessor to measure the load.
