Abstract
A digital signal processing apparatus and information processing system provide sufficient arithmetic operation performance to process high rate signals in real time and high programming performance to deal with various applications. A group of processor elements is constituted by individual processor elements each formed by disposing an arithmetic and logic unit on the bit lines of a multiport memory wherein their number is equal to or larger than the number of the data bits in a series of serial data, and the plurality of processor elements constituting the group of processor elements are uniformly controlled by controllers mounted on the same silicon chip. Consequently, the multiport memory functioning as a buffer for input data and the arithmetic and logic unit are closely joined together, so data can be communicated smoothly between them. Since the plurality of processor elements are controlled by a single controller so as to operate as a parallel computer, a digital signal processor with a high processing speed can be implemented.
