Dynamic Compilation Framework

Question: Write an essay on Dynamic Compilation Framework for Controlling Microprocessor Energy and Performance. Answer: Energy and power management forms an important part in the performance of any hardware system. One of such mechanism called as Dynamic voltage and frequency scaling (DVFS) is presented in this paper for optimizing the power and energy in the hardware system of microprocessor. An extensive real time performance analysis for DVFS is done for measuring CPU current and voltage. Algorithms developed for DVFS has been divided in two parts called decision and selection algorithm. Readings of experimental results are analyzed to compare the DVFS performance with other techniques. It presents extensive analysis of dynamic and static methods using experimentation. Different specifications were discussed in terms of performance. SPEC2KFP, SPEC2K INT, SPEC95 FP, Olden has energy saving of 70%, 44%, 64%, 61% respectively. On standard the method guide to 3 to5 times improvement in the EDP or energy delay product as compared to static voltage scaling. A design framework has been designed for this. The results were based on different methods described. The improved efficiency and promising results gives the DVFS an edge ahead of other technologies. Although an improvement is possible, if framework is designed for particular microprocessors. Also by overcoming challenges faced by DVFS, a more efficient design can be prepared.
