ABSTRACT:
A system for communicating data between two control units each capable of executing independent operations and having a memory for operations, the system is provided with a new data generator on one control unit. The new data generator generates new data for a selected item of the other control unit. The new data is combined with address data corresponding to the selected item of the memory of the other control unit to generate transmission data. The transmission data is sent to the other control unit and the new item data is written on the memory at the address specified by the transmission data. The data communication system communicates between the two control units data for a first kind of operations and data for a second kind of operations selectively. The first kind data is communicated repeatedly while the second kind data is communicated a single time.
