In the last few years speed of processor is increased every six month to one year. We have requirement of parallel processing for some scientific research work such as bio-medical research, earthquake analysis and for high definition video. For parallel processing we have to require multi-core architecture. Multi-core means more than one similar type of core always in even no. is integrated on single chip with given area. With multi-core architecture we can improve system performance up to some limitation because we can’t reduce transistor size. If we reduce transistor size then density of transistor on chip is increase but heating effect increase it affects working of processor and some time processor chip become useless. With help of reconfigurable heterogeneous architecture we can improve the performance of the system. In heterogeneous architecture all core are different in size, frequency and functionality also different instruction set is used for programming. Heterogeneous architecture means combination of CPU, GPU, DSP and FPGA processor integrate on single chip. In today’s PC and laptop there are CPU and GPU both are integrate on single chip, with this combination we can achieve high speed. In future different combination like CPU with DSP, CPU with FPGA and all are integrate on single chip for improvement of speed and performance of system with limited area and given power budget.
