Abstract

A parallel data processing system performs a data processing by using a plurality of data processing units, namely, processor elements, synchronously. The parallel data processing system comprises a plurality of data processing units, a plurality of trays, and a clock generator. The plurality of trays are connected to respective data processing units and have a function of storing a plurality of data and a function of transmitting the data. The clock generator is producing a clock so that the data transfer between the trays and between the trays and the data processing units, and the data processing in the data processing unit is executed synchronously. Data are transferred between trays during the period in which they are processed, thus substantially eliminating the data transmission time. Furthermore, the interim result of the operation is stored in the tray and thus when the later operation needs the interim result, the interim result stored in the tray is efficiently used without the need to access the memory provided in the data processing apparatus.
