Title: Timer monitor control system
Inventor: SONE NANAO
IPC: G06F11/30
Filed: 1990-11-30
Abstract: PURPOSE:To shorten the CPU occupying time and to attain the overlap processing by performing plural timer monitor processing operations carried out by a certain processing process with a single timer request. CONSTITUTION:A processing process 3 monitors the state of a requested monitor subject 6 in response to the monitor request given from a requester 1 and then asks a timer 5 to inform the end of the timer 5 after a prescribed time when an uncomplete answer is received and a monitor subject where the value of a timer counter 3-2 is uncomplete does not exist. Otherwise the value of the counter 3-2 is added. Then the value of the counter 3-2 is subtracted when the process 3 receives the information of the end of the timer from the timer 5. At the same time, a dummy timer is produced to repetitively monitor the state of the subject 6. Thus plural timer monitor processing operations carried out by a certain process 3 are attained with a single timer request, the CPU occupying time is shortened, and the overlap processing is attained.
