A Library Development Framework for a Coarse Grain Reconfigurable Architecture

A framework for efficiently capturing the rich micro architectural space of a substantial Matlab like library of DSP functions for a regular Coarse Grain Reconfigurable Architecture (CGRA) fabric is proposed. A subset of C has been proposed to model the DSP functions and an automatic tool to generate the configware for the CGRA fabric developed. A method to estimate the average energy of such functions is reported with error margin of less than 3%. Such a framework is proposed as the basis for raising the abstraction to automate synthesis of the entire physical layers.
