PipeIt: A Pipeline Programming Framework For Embedded Processor Array Systems-on-Chip

This paper presents thePipeIt framework for developing pipelined applications targeted at tightly-co upled processor arrays on a chip. The framework includes a component programming and wiring model, a runtime environment, and a corresponding toolchain. It enables the programmer to develop applications in a high-level manner, structuring the code at the finest possible/meaningful leve l of granularity, without caring about how this will be deployed and executed. At runtime, the stages of the pipeline are distributed among the available processors. This arrangement can be changed dynamically when another PipeIt application needs to be executed concurrently. We discuss and demonstrate a complete embedded system prototype.
