Automatic Extraction of Pipeline Parallelism for Embedded Software Using Linear Programming
Source: Technische Universität Darmstadt
The complexity and performance requirements of embedded software are continuously increasing, making Multiprocessor System-on-Chip (MPSoC) architectures more and more important in the domain of embedded and cyber-physical systems. Using multiple cores in a single system reduces problems concerning energy consumption, heat dissipation, and increases performance. Nevertheless, these benefits do not come for free. Porting existing, mostly sequential, applications to MPSoCs requires extracting efficient parallelism to utilize all available cores. Many embedded applications, like network services and multimedia tasks for voice-, image- and video processing, are operating on data streams and thus have a streaming-based structure. Despite the abundance of parallelism in streaming applications, it is a non-trivial task to split and efficiently map sequential applications to MPSoCs.
