Configuration Memory Based Dynamic Coarse Grained Reconfigurable Multicore Architecture for 8 Point FFT

Hardware reconfigure model provides flexibility to same hardware for different application. Coarse-grained Architecture (CGRA) is best example of the reconfigurable system. This paper proposed and configuration memory based CGRA system which can change the hardware Configuration dynamically according to applications. Configuration memory will consist of multiple such DFGs that will configure the hardware according to the detected application. Author has proposed CGRA system with 4X4 Processing Elements (PE) and configured for 8 point FFT application. The necessary Data flow diagram/graph (DFG) also presented and implemented.
