Parallel architectures have become an increasingly popular method in which to achieve high performance with low power consumption. In order to leverage these benefits, applications are decomposed into multiple computational modules (tasks) that collectively operate and communicate in parallel. In this paper, we present a scalable and highly parametric streams-based communication architecture for inter-module communication for FPGA-based systems - SCORES. This communication architecture improves on previous methods by providing increased application specialization and heterogeneous module clock frequencies, as well as providing a means for low latency communication and data throughput guarantees.
