Modelling Heterogeneous DSP–FPGA Based System Partitioning with Extensions to the Spinach Simulation Environment
Cavallaro, Joseph R.
In this paper we present system-on-a-chip extensions to the Spinach simulation environment for rapidly prototyping heterogeneous DSP/FPGA based architectures, specifically in the embedded domain. This infrastructure has been successfully used to model systems varying from multiprocessor gigabit ethernet controllers to Texas Instruments C6x series DSP based systems with tightly coupled FPGA based coprocessors for computational offloading. As an illustrative example of this toolsets functionality, we investigate workload partitioning in heterogeneous DSP/FPGA based embedded environments. Specifically, we focus on computational offloading of matrix multiplication kernels across DSP/FPGA based embedded architectures.
