Integration of Power Saving Techniques in the UNISIM Simulation Framework through the Shadow Module design paradigm

چکیده
Performance is no longer the only metric dominating modern system-level design. Power is emerging as major constraint to consider during system development. Consequently, several CAD tools with power estimation capabilities in addition to performance figures have been developed. Among these tools, UNISIM is a simulation framework that enables the architects to rapidly design a new system at different levels of granularity in systemC. It allows quick design space exploration and offers cycle accurate performance evaluation. We propose the shadow module, a new design paradigm for UNISIM that enables the framework to account for energy estimation. In this respect, we discuss the implementation of various cache power saving techniques. Experimental results utilizing realistic benchmarks show that power and performance figures can be easily identified with our enhanced analysis framework.

متن کاملTechno-Economic Assessment of Different Inlet Air Cooling Systems in Warm Dry & Wet Climate Stations
Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

In this paper thermodynamic modeling and comprehensive performance analysis of a real integrated solar combined cycle (ISCC) power plant are performed. Performance of the plant cycle is assessed in off-design condition and in two operation modes of power-boosting and fuel-saving. Such an approach has not been considered for an ISCC plant in the previous studies. Under studied ISCC which is loca...

Based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. The first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. The second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....
