Static or Dynamic: Trade-Offs for Task Dependency Analysis for Heterogeneous MPSoC

Abstract

Out-of-order execution scheme is one of the most promising technologies for task level parallelization in MPSoC design paradigms. However, it still poses a significant challenge to efficiently analyze the inter-task dependencies. This paper applies a traditional instruction level Scoreboarding algorithm at the task level in two forms: dynamic and static. A heterogeneous MPSoC prototype has been developed on FPGA with state-of-the-art dynamic partial reconfigurable technologies. The leverage between static and dynamic scheduling using task dependency analysis is obtained. Experimental results demonstrated a trade-off for the two modalities.
