Automated code generation of streaming applications for C6000 multicore DSPS

摘要

With the increasing complexity of modern, state-of-the-art Multiprocessor Systems on Chip (MPSoCs), recent trends in embedded software design show a rising interest in using dataflow models of computation for parallel programming. These models of computation do not only match the requirements of streaming applications found in the telecommunication, wireless and multimedia domain, but also provide an easier entry path in dealing with parallelism by reusing large parts of the sequential programming paradigm. As a consequence, it is highly desired to have an automated approach for bridging the gap between an application's specification using a dataflow model of computation and the actual binary which is executed on the hardware. In this paper, we present a toolflow which completely automates the process of code generation for Texas Instrument's C6000 high performing, multicore, Digital Signal Processor (DSP) platforms. The mapping of individual processes to specific cores is achieved by a user-defined mapping file. This automated code generation for streaming applications opens up a wide range of possibilities as a research and educational platform.
