prefetchn.

Brit.

/ˈpriːfɛtʃ/, U.S.

/ˈpriˌfɛtʃ/

Origin: Formed within English, by derivation. Etymons: pre- prefix, fetch n.¹

Etymology: < pre- prefix + fetch n.¹ Compare slightly later prefetch v.

Computing.

The action or process of prefetching data or code; an instance of this.

ΚΠ

1969 Computer Group News Mar. 11/1 This is the combined phenomenon of increased useful bandwidth and prefetch of future valuable information.

1978 Computer Dec. 7/2 Prefetches can be done in parallel, simultaneously with normal program operation, thus avoiding CPU idle time.

1996 H. G. Cragon Memory Syst. & Pipelined Processors ii. 102 These considerations include the time interval between the prefetch and the actual need.
