Abstract

The paper investigates the reduction of dynamic power for streaming applications yielded by asynchronous dataflow designs by using clock gating techniques. Streaming applications constitute a very broad class of computing algorithms in areas such as signal processing, digital media coding, cryptography, video analytics, network routing and packet processing and many others. The paper introduces a set of techniques that, considering the dynamic streaming behavior of algorithms, can achieve power savings by selectively switching off parts of the circuits when they are temporarily inactive. The techniques being independent from the semantic of the application can be applied to any application and can be integrated into the synthesis stage of a high-level dataflow design flow. Experimental results of atsize applications synthesized on FPGAs platforms demonstrate power reductions achievable with no loss in data throughput.
