Abstract
Heterogeneous platforms, that integrate CPU and FPGA-based processing units, are emerging as a promising solu- tion for accelerating various applications in the embedded system domain. However, in this context, comprehensive studies that combine the theoretical aspects of real-time scheduling of tasks along with practical runtime architectural characteristics have mostly been neglected so far. To fill this gap, in this paper we propose a real-time scheduling algorithm with the objective of minimizing the overall execution time under hardware resource constraints for heterogeneous CPU+FPGA architectures. In particular, we propose an Integer Linear Programming (ILP) based technique for task allocation and scheduling. We then show how to implement a given scheduling on a practical CPU+FPGA system regarding current technology restrictions and validate our methodology using a practical RISC- V case-study. Our experiments demonstrate that performance gains of 40% and area usage reductions of 67% are possible compared to a full software and hardware execution, respectively.
