A control apparatus for an internal combustion engine includes a plurality of sensors for producing signals indicative of operating conditions of the engine, an input/output unit adapted to receive sensed signals and to deliver control signals to actuators which control an energy conversion function of the engine and a central-processor unit coupled with the input/output unit and adapted to execute an arithmetic operation for producing data to be sent to the input/output unit. The input/output unit includes a first register file having a plurality of registers for storing constants and data produced by the central processor unit and a second register file having a plurality of registers for storing signals indicative of conditions of the engine as of a selected instant in time during which the engine is operative. A comparator is provided to compare the contents of the selected one of registers of the first register file with the content of the selected one of registers of the second register file, and the resultant output is applied to the actuators. The first register file further includes a register storing a prescribed constant with which selected ones of the registers of the second register file are compared by the comparator in response to the contents of prescribed ones of the second register file causing the comparator to produce an output.

In a processor-controlled apparatus for controlling the operation of an internal combustion engine for which sensor means produce signals representative of operating conditions of the engine, and being coupled to actuator means for controlling respective energy conversion functions of said engine in response to control signals applied thereto, a control apparatus comprising, in combination: first means for generating an engine control timing signal pattern through which operational events of said engine are controlled; second means for storing predetermined engine control codes; third means, coupled to said first means, for generating respective engine timing codes the values of which are selectively modified by said engine control timing pattern; fourth means, coupled to said second and third means, for comparing respective ones of said engine control codes with respective ones of said engine timing codes and producing respective output signals when said respective engine control codes define a prescribed relationship with respect to said engine timing codes; fifth means, coupled to said fourth means, for producing control signals to be coupled to said actuator means in response to the output signals produced by said fourth means; and sixth means, coupled to said third and fourth means, for causing said fourth means to compare a respective engine timing code with a preselected engine control code in response to said fourth means producing an output signal associated with said respective engine timing code.
