Abstract
A data processing system enables faster exchange of data between data processing units having a CPU, and simplifies the writing of a data exchange program for the data processing units. A data processing apparatushas a communication unitwith a first storage unitand a second storage unitThe first storage unitis used for sending data from the first data processing unitto the second data processing unitThe second storage unitis used for sending data from the second data processing unitto the first data processing unitData can therefore be asynchronously exchanged between the data processing units without coordinating control of CPU operations in the data processing units, and control of data communication between the data processing units is simplified.
