A Concept of Input/Output Signal Processing for Microprocessor Engine Control Systems

A new input and output (I/O) signal processing concept for microprocessor engine control systems is presented. An analysis of the relations between data resolution and control accuracy show that they are effected by sensor signal forms. The concept of a microprocessor engine control system with a specially designed I/O interface LSI is proposed. An output circuit with a structure that allows fast data processing and minimizes LSI chip size are also presented.
