Abstract

PURPOSE:To perform a program correction in real time, by using a memory having two input/output means when a control program is produced for a car engine, an air conditioner, etc. and designating the memory address of one side while the program is under the control at the other side. CONSTITUTION:A data bus 2, an address bus 3 and a control bus 4 are lead out of a CPU1 that executes a prescribed program control. Then a program correcting part 12 is connected to each of these buses 2-4. A 2-port RAM15 is connected to an interface circuit 14 of the part 12. The data, address and control buses 2'-3' of the circuit 14 are connected to one port of the RAM15; while a program correcting device 16 is connected to the other port. In addition, a data bus 17 is connected between the RAM15 and the device 16. Then the control is executed by the prograom of one side of the RAM15, and an address is designated by the other progrom. thus the program is corrected in real time.
