We propose a data filtering method to reduce the power consumption of high-end processors with multiple execution cores. Although the proposed method can be applied to a wide variety of multi-processor systems including MPPs, SMPs and any type of single-chip multiprocessor, we concentrate on Network Processors, where most of the existing architectures use the multiple core design methodology.

The power consumption of peripheral devices is a significant portion of the overall energy usage of a mobile platform. To take advantage of idle times, most devices offer the ability to transition into low power states. However, the amount of energy saved by utilizing these sleep states depends on the lengths and number of idle periods experienced by the device. This paper describes a new proce...

With the trend towards wider instruction issue and larger instruction windows, register les grow both in terms of size and number of read/write ports. However, large multi-ported register les consume a substantial amount of power, and may also limit the cycle time of a processor. This work attempts to address these issues by taking advantage of the facts that many register accesses show extreme...

The widespread use of cloud computing services is expected to increase the power consumed by ICT equipment in cloud computing environments rapidly. This paper first identifies the need of the collaboration among servers, the communication network and the power network, in order to reduce the total power consumption by the entire ICT equipment in cloud computing environments. Fivefundamental pol...
