Performance Analysis of a Multicore Based LEON3 Integrating a RTOS

Abstract

Embedded system is characterized by three principal categories: real-time performance, low coast (low hardware occupation) and a low power/energy consumption. Measuring the performance of an embedded system versus the cost for designs has become a very important interest for any embedded system design process. In goal to improve the speed of a system, the integration of many processors in the same chip can be a solution but it requires saving power in electronic systems. In this paper a new method is used to evaluate a hardware performance of FPGA based on different embedded systems and running freely available benchmarks. A hardware implementation and real-time performance measurements of an embedded system (mono-processor, bi-processor and quad-processor based LEON3 soft-core) is done with the integration of a Real Time Operating System open-source, like eCos.
