Abstract

PURPOSE: To reduce the amount of data transmitted between a main processor and local processor by processing information on the basis of absolute time.
CONSTITUTION: Main processor 1 consists of present-time timer 6, control absolute- time register 7, control information resister 8, control time detecting logic part 9 which detects that the control time comes by comparing values of timer 6 and register 7 each other, control judging logic part 10 which judges whether a signal device should be controlled depending upon the contents of register 8, and control relative-time calculating logic part 11 which finds the control relative time and sends out it to local processor 4 together with the contents of register 8. Constant time tc more than the dispersion of the processing time due to load variation, etc., is set to processor 1, which exercises judgement in reference with control information before tc of control absolute time Tc and allows processor 4 to output control information at a required point in time.
