The power consumption of programs and algorithms is currently a very active research field. This includes the investigation of the effect of different programming techniques on power consumption. Some programming techniques have already been studied intensively. However, there are techniques that did not get as much attention as needed so far. One of these techniques is the vectorization of programs,...
This paper presents an improved differential evolution (DE) algorithm for multi-objective optimization in the discrete domain, applied to a cache memory hierarchy exploration problem, aiming to reduce the energy consumption and to increase the performance to process an embedded application. The architecture exploration is based on cache parameters adjustments and the memory hierarchy is composed of...
Most critical and major in growing technology for High Performance of demand of power & energy and an urgent problem in powering technologies. Energy optimization is an enabling power Management. The Consumption of Energy Should be ascertainable not only to Gate Level or Register Transfer (RT) Level but also to the System Level. Reducing the Energy Consumption of system not deviating the overall...
While performance and power consumption of processors present a classic trade-off in designing embedded hardware, software can be optimized in favor of both performance and energy. We evaluate the impact of optimizations at different stages of designing embedded software. We show that algorithm choice and compiler optimizations aimed at improving performance can also reduce energy consumption of an...
With the increase of high performance computing systems' scale, the power consumption of HPC systems greatly increase, among which the power consumption of massive storage system occupies an important role. Measurements and analyses of massive storage system are significant for reducing the power consumption of storage system. Tianhe-1 comes in at No.5 in Nov. 2009 Top500 list with the highest ranking...
Emerging trends in applications with the requirement of considerable computational capacity and decreasing time-to-market have urged the need of multiprocessor systems. With the advent of multiprocessor systems, there is an increased demand to efficiently control their energy and power budget. As the technology scales to increasingly smaller feature sizes, the static power consumption is expected...
Energy and performance efficiency of fetch unit is critical to processor design. Trace cache which stores dynamic instruction flow to form instruction trace can significantly improve performance efficiency by fetching multiple blocks from trace cache in a given cycle. Conventional trace cache (CTC) design suffers energy inefficiency because of its simultaneous access to both instruction cache and...
