Each node or DPU independently computes a partial result as a function of the data received from its upstream neighbors, stores the result within itself and passes it downstream. Systolic arrays were invented by Richard P. Brent and H.T. Kung, who developed them to compute Greatest common divisors of integers and polynomials. 〔http://www.eecs.harvard.edu/~htk/publication/1984-ieeetoc-brent-kung.pdf〕 They are sometimes classified as Multiple Instruction Single Data (MISD) architectures under Flynn's Taxonomy, but this classification is questionable because a strong argument can be made to distinguish systolic arrays from any of Flynn's four categories: SISD, SIMD, MISD, MIMD, as discussed later in this article. The parallel input data flows through a network of hard-wired processor nodes, resembling the human brain which combine, process, merge or sort the input data into a derived result. Because the wave-like propagation of data through a systolic array resembles the pulse of the human circulatory system, the name systolic was coined from medical terminology. The name is derived from Systole (medicine) as an analogy to the regular pumping of blood by the heart. ==Applications== Systolic arrays are often hard-wired for specific operations, such as "multiply and accumulate", to perform massively parallel integration, convolution, correlation, matrix multiplication or data sorting tasks. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Systolic array」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
