instruction cycle

[in′strək·shən ‚sī·kəl]
(computer science)
The steps involved in carrying out an instruction.

instruction cycle

The fundamental sequence of steps that a CPU performs. Also known as the "fetch-execute cycle," it is the process whereby a single instruction is executed. The first half of the cycle transfers the instruction from RAM to the instruction register (fetch) and decodes it. The second half executes the instruction. See machine language.

In contrast, NetX Duo not only achieves 93-95% of wire speed on the STM32 processor, but does so using only 21-34% of the processor's CPU cycles.
VSS Monitoring's new defragmentation capabilities lower the cost of ownership on media and network intelligence tools by reducing CPU cycles on voice and video analyzers while increasing bandwidth for relevant traffic.
Because helioseismology is computationally intensive, regular monitoring of the whole Sun is not yet possible-"we don't have enough CPU cycles," says Ilonidis-but he believes it is just a matter of time before refinements in their algorithm allow routine detection of hidden sunspots.
The request would more appropriately be handled by a video-optimization server, but instead is handled by the WAP gateway, wasting CPU cycles.
The new release also improves: execution speed, with optimised memory handling delivering performance increases of 30% over the previous VirtualBox release; network performance, delivering increased throughput, while reducing CPU cycles, through a new paravirtualised network driver; and display performance via a new 2D Video Acceleration feature for Windows guests.
