Performance evaluation of multicore LEON3 processor

Abstract

Complexity of embedded systems becomes more and more popular which integrates a hardware and software parts on common platform. This complexity can be inferred on the performance of such systems. This paper, explains the characteristics of LEON3 Soft Core processor and its implementation for several configurations, including single, dual, tri, and quad cores, as well as with and without the hardware FPU and cache system. We propose a performance evaluation methodology affected by a benchmark test. Measuring the performance of such systems becomes a very important task for any embedded system design process. The performance of such systems is affected by a benchmark test discussed for different configuration of LEON3 processor.
