PiMM: Parameterized and Interfaced dataflow Meta-Model for MPSoCs runtime reconfiguration

Abstract : —Dataflow models of computation are widely used for the specification, analysis, and optimization of Digital Signal Processing (DSP) applications. In this paper a new meta-model called PiMM is introduced to address the important challenge of managing dynamics in DSP-oriented representations. PiMM extends a dataflow model by introducing an explicit parameter dependency tree and an interface-based hierarchical compositionality mechanism. PiMM favors the design of highly-efficient heterogeneous multicore systems, specifying algorithms with customizable trade-offs among predictability and exploita-tion of both static and adaptive task, data and pipeline paral-lelism. PiMM fosters design space exploration and reconfigurable resource allocation in a flexible dynamic dataflow context.
