Modelling Heterogeneous DSP-FPGA Based System Partitioning with Extensions to the Spinach Simulation Environment

Abstract

In this paper we present system-on-a-chip exten- sions to the Spinach simulation environment for rapidly prototyp- ing 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 com- putational offloading. As an illustrative example of this toolsets functionality, we investigate workload partitioning in heteroge- neous DSP/FPGA based embedded environments. Specifically, we focus on computational offloading of matrix multiplication kernels across DSP/FPGA based embedded architectures. I. INTRODUCTION
