Abstract

PURPOSE:To provide an internal data display unit with superior LSI simple in configuration with high performance and economy for the general controller of an internal combustion engine. CONSTITUTION:A general controller for an internal combustion engine is composed by connecting input/output port 6 interfaced via address bus lines, data bus lines and control bus lines with a RAM 3, a control program storage ROM5 and various sensors and actuators to an engine controlling CPU1. The internal data display unit connected to such a controller consists of buffers 8, 9 for amplifying the respective signals of the address, data and control of the controller, a decoder 10 for determining the area of a RAM4, a CPU2 for calculating necessary write of data in the RAM4, input/output port 7 for producing the processed data, and a display unit 11 for displaying the state readable at the output signal.
