英语词汇“logical shift”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

b. Computing and Electronics. Of or pertaining to the logic (logic n. 4) of computers and similar equipment; designed to carry out processes on electrical or other signals analogous to the processes of reasoning, deduction, etc., employed in (formal) logic; logical element = logic n.; logical operation: see Compounds; logical shift, a displacement of the digits of a sequence by a specified number of positions in a way that is not equivalent to multiplication by an integral power of the base; esp. a cyclic shift, in which digits taken from one end reappear, in the same order, at the other end.In some of the uses below logical can equally well be regarded as having the sense of 1.

1950 C. B. Tompkins & J. H. Wakelin High-speed Computing Devices (Engin. Res.

Such circuits are variously known as gates, coincidence circuits, Rossi circuits, or logical and circuits.
