Guiding Power/Quality Exploration for Communication-Intense Stream Processing

In this paper, we explore the power/quality trade-off for streaming applications with a shift from the computation to the communication aspects of the design. The paper proposes a systematic exploration methodology to formulate and traverse power/quality trade-off for the class of adaptive streaming applications. The formalization enables to procedurally transition from a set of design requirements to architecture goals. The architecture goals can then be realized through design choices yielding system designs that meet the initial requirements. The reported results are based on an actual implementation of Mixture of Gaussian (MoG) background subtraction on Xilinx Zynq platform.
