Abstract

PURPOSE: To perform engine control properly by arranging a memory circuit which stores operation data, at the operation processing part for controlling an internal combustion engine.
CONSTITUTION: With the operation processing part 1 which operates the input information from a variety of sensors according to the operation processing means predetermined, a first memory circuit 2 for storing data is connected. The actuator control part 3 which allows the data signal of the processing part 1 to be synchronized to the operation of the engine is equipped with the memory operation instruction generating circuit 3a which transmits memory operation instruction on demanding and a second memory circuit 3b which stores the data of the circuit 2. The judging circuit 4 which judges whether the memory operation instruction from said generaging circuit 3b is generated or not delays the operation data transmission to the control part 3 till the completion of memory operation of the second memory circuit 3b by means of a memory operation delaying circuit 5 which operates according to the output of the judging circuit, and precisely receives the data which are generated synchronously.
