Abstract

PURPOSE:To promote reduction in executing time of operations by storing data in read and write memory (RAM) at the time of initialization dividing into memory for storing the method of control and that for storing control values the read only memory (ROM) in the microcomputer used for controlling an internal combustion engine or the like. CONSTITUTION:An interface circuit 2 that reads the data of a solenoid valve for jetting fuel to perform electronic control fuel jet of an internal combustion engine, RAM3, ROM4a storing only the method of control and ROM4b storing only control values are connected to a microcomputer 1. At the time of initialization of the software built in ROM4a, the control values in ROM4b are stored in RAM3. In an actual control routine, operations are carried out referring to the data in the RAM3, if necessary. Concerning table data, they are not read at the time of initialization, but operations are carried out referring to the table data in the ROM4b. Thus, it is possible to reduce executing time of operations and also make easy a change in the specification of control values.
