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.

The next network card setting informed by [13] to reduce CPU load is called Large Receive Offload, where the network card will combine several Ethernet frames into one receive to save CPU cycle, but on the other hand it gives additional task to the network card.
Suppose constant CPU cycle time for each algorithm as 20 seconds.
The parallelization process consists of (i) evaluating the computational intensity of data fusion by calculating CPU cycles; (ii) octree-based decomposition of the computational domain into subdomains according to the CPU cycle threshold; and (iii) scheduling subdomains to the computing nodes of a cluster computer for parallelized D-S evidential fusion.
This is easier to determine for storage than computing power, because it is hard to standardise a CPU cycle across different chips and platforms.
(Some implementations use polling to avoid transmit interrupts altogether [Macklem 1991].) During overload, the unmodified system would not make any progress on applications or transport protocols; the use of polling, queue-state feedback, and CPU cycle limits should give the modified system a chance to make at least some progress.
"At virtual infrastructure scale, every second in a backup counts, and every CPU cycle consumed by a virtual appliance means one more chance of interrupting compute."
Peripheral blocks integrated in the ST10F168 include a CAN interface, 32-channel capture and compare unit, five 16-bit timers, 16 channels of 10-bit analog-digital converters with a conversion rate down to 7.76us, a four channel pulse-width modulation unit, an asynchronous communications channel, synchronous communication channel, 56 interrupt sources with a sample rate down to 40ns, eight channel peripheral event controlled interrupts transferring data within one CPU cycle, an on-chip bootstrap loader, an idle mode and two powerdown modes.
We had two paths to cache allowing two memory accesses per cycle, and to match the cache access time to the CPU cycle, it was pipelined five deep (necessary because of the low level of circuit integration).

Diverting such tasks to tailored hardware accelerators offloads suitable workloads and frees a server's CPU cycles for higher value workloads.
This will minimize CPU intervention, saving CPU cycles and significantly reducing CPU power and cost.
