Logic synthesis method of digital circuits designed for implementation with embedded memory blocks of FPGAs

Abstract

The paper presents logic synthesis method targeted at FPGA architectures with specialized embedded memory blocks (EMBs). Existing methods do not ensure effective utilization of the possibilities provided by such modules. The problem of efficient mapping of combinational and sequential parts of design can be solved using decomposition algorithms. The main question of this paper is the application of decomposition based methods for efficient utilization of modern FPGAs. It will be shown that functional decomposition method allows for very flexible synthesis of the designed system onto heterogeneous structures of modern FPGAs composed of logic cells and EMBs. Finally we present results of the experiments, which evidently show, that the application of functional decomposition algorithms in the implementation of typical signal and information processing systems greatly influences the performance of resultant digital circuits. © Springer-Verlag Berlin Heidelberg 2011.
