Abstract

PURPOSE: To accomplish the titled conversion simply and in a short time by a method wherein a memory, into which tale data converted from cycle to rotational frequency are written, is provided at an electronic controlling device for internal combustion engine using a stored program computer.
CONSTITUTION: A central processing unit 1 is connected through address data lines 6 and 7 to a memory 2 into which controlling program is written. Signals consisting of various outside informations are read through an input interface circuit 4 into the central processing unit 1 and, after the predetermined processing, through an output interface circuit 5, outputted as controlling signals. Now, the central processing unit 1 is further connected through data lines 8 and 9 to another memory 3 into which, for example, table data converted from the cycle T to the rotational frequency N are written. Then, when the cycle T is T1, the corresponding address is accessed and as a result the corresponding rotational frequency N1 is outputted through the data lines 9 and 6.
