Abstract
A parallel arithmetic-logical processing device in which arithmetic-logical processing is shared among and executed in a parallel fashion by a plurality of processing elements. The device includes a large-capacity serial access memory for continuous reading/writing of large-scale data, a small-capacity serial access memory for continuous reading/writing of small-scale data and a high-speed general-purpose random access memory for random writing/readout of small-scale data. A central processing unit (CPU) causes the memories to be used or not used depending on the scale of the arithmetic-logical processing. Since the serial access memory executes continuous data writing and reading, high-speed access may be achieved, so that it can be manufactured inexpensively with a large storage capacity. Consequently, the processing speed in the CPU may be increased, while the parallel arithmetic-logical processing device may be manufactured inexpensively.
