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

2. Computing. More fully carry-lookahead. A method in computational arithmetic whereby the individual elements of an adder (adder n.² 3) are capable of determining when addition performed by preceding stages will generate output which has to be carried to subsequent stages; an implementation of this method. Frequently attributive.

ΚΠ

1959 Proc. Eastern Joint Computer Conf. 52/1 This carry look-ahead results in a delay time of 150 mμsec for 96-bit binary number additions.

1963 I. Flores Logic Computer Arithm. v. 83 Let us examine an adder which performs the carry function with a lookahead on several levels.

1971 IEEE Trans. Computers 20 863/1 The method of obtaining carries simultaneously using the well known technique for binary adders of carry look-ahead is easily extended.

1989 IEEE Jrnl. Solid-state Circuits 24 358/1 The use of the carry lookahead..principle..for high-speed arithmetic units remains dominant.

2002 G. R. Wilson Embedded Syst. & Computer Archit. iv. 60 Even though there are now several layers of look-ahead logic, this adder has a substantial advantage in speed of operation.
