Joint communication scheduling and interconnect synthesis for FPGA-based many-core systems

Abstract

This work proposes an automated methodology for optimizing FPGA-based many-core interconnect architectures. Based on the application communication requirements, the methodology concurrently defines the structure of the interconnect and the communication task scheduling, taking into account possible dependencies between tasks under given area constraints. The resulting architecture improves the level of communication parallelism that can be exploited while keeping area costs low. The paper thoroughly describes the proposed approach and discusses a few case-studies showing the impact of the proposed technique.
