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.

Dependent claims

A parallel data processing system including a plurality of data processing units comprising:

a plurality of trays, only a part of said plurality of trays having outputs operatively connected to said plurality of data processing units and each of said plurality of trays being connected to an adjacent said tray, said part of said plurality of trays being connected to said plurality of data processing units for transmitting and receiving data to and from said plurality of data processing units and said adjacent trays and for storing said data transmitted from said plurality of data processing units and said adjacent trays, and a remaining part of said plurality of trays being not connected to said plurality of data processing units for transmitting and receiving data to and from said adjacent trays and for storing said data transmitted from said adjacent trays;
and
a clock generator, connected to said plurality of trays and said plurality of data processing units, which generates a clock signal for use in synchronously performing the transfer of said stored data between said plurality of trays and said plurality of data processing units and the data transfer between said part of said plurality of trays and said plurality of data processing units and a data process in said plurality of data processing units.
