Abstract:
In this paper, a heterogeneous Multiprocessor System-on-Chip (MPSoC), controlled by a dedicated task scheduling unit, is presented. This unit, known as CoreManager, is responsible for dynamic data-dependency checking, task scheduling, processing element allocation and data-transfer management. Three different CoreManager approaches are analyzed and compared. An analytical model is derived for each CoreManager implementation. The configuration parameters for the models are determined through system analysis. For this purpose, a tool flow has been developed to build the MPSoC and generate data traces. For the benchmarks employed, the relative error of the analytical model was shown to be lower than 6.3 % on component and 6.9 % on system level compared to the measurements.
