Co-synthesis with custom ASICs

- This paper introduces the first hardwarekoftware co-synthesis algorithm that optimizes the implementations of ASICs that are used as processing elements for the embedded systems. Many real time embedded systems are composed of heterogeneous processing elements, such as general purpose CPUs, ASICs and FPGAs. Previous work has not considered how to select one of several possible ASIC implementations for a specific task. We have developed a heuristic iterative improvement algorithm for distributed embedded system cosynthesis. We use Monet, a behavioral level architectural exploration system, to generate multiple implementations of a behavioral description of an ASIC and to analyze their performance. To the best of our knowledge, this is the first cosynthesis algorithm that takes into account the impact of different ASIC implementations of tasks on system performance and cost in the co-synthesis process.
