Compilation for heterogeneous SoCs : bridging the gap between software and target-specific mechanisms

Abstract : Current applications constraints are pushing for higher computation power while reducing energy consumption, driving the development of increasingly specialized socs. In the mean time, these socs are still programmed in assembly language to make use of their specific hardware mechanisms. The constraints on hardware development bringing specialization, hence heterogeneity, it is essential to support these new mechanisms using high-level programming. In this work, we use a parametric data flow formalism to abstract the application from any hardware platform. From this premise, we propose to contribute to the compilation of target independent programs on heterogeneous platforms. These developments are threefold, with 1) the support of hardware accelerators for computation using actor fusion, 2) the automatic generation of communications on complex memory layouts and 3) the synchronization of distributed cores using hardware mechanisms for scheduling. The code generation is illustrated on a telecommunication dedicated heterogeneous soc.
