Out-of-order Execution

In computer engineering, out-of-order execution (OoOE or OOE) is a paradigm used in most high-performance microprocessors to make use of instruction cycles that would otherwise be wasted by a certain type of costly delay. In this paradigm, a processor executes instructions in an order governed by the availability of input data, rather than by their original order in a program. In doing so, the processor can avoid being idle while data is retrieved for the next instruction in a program, processing instead the next instructions which are able to run immediately.

Famous quotes containing the word execution:

    I will soon be going out to shape all the singing tomorrows.
    Gabriel Péri, French Communist leader. Letter, July 1942, written shortly before his execution by the Germans. Quoted in New York Times (April 11, 1943)
