In the field of embedded system, there is a trade-off between power/performance optimization. Furthermore, demand for High Performance Computing (HPC) is increasing as well [1], hence many heuristics techniques were presented at various development levels such as hardware software co-design, schedulers and optimal code compilation. However, there is a critical issue of power and heat dissipation with these HPC. This paper presents a fuzzy logic based Dynamic Voltage and Frequency Scaling (DVFS) techniques to reduce the power without compromising the performance. For real time implementation, Leon3 architecture was implemented on Vertex 5 FPGA board. Results were tested using both series and parallel benchmarks and 19 % reduction in power consumption is observed.
