Estimation Method Considering OS Overheads for Embedded Many-Core Platform

Embedded systems such as automotive systems require high computational power and low power consumption. To meet these requirements, many-core processors have attracted attention. Compared with single-core processors, many-core processors can execute multiple processes in parallel, allowing for improved power consumption and performance. Due to their performance, many-core processors can be used in automotive systems which have strict real-time requirements. Therefore, it is important to obtain accurate hardware and software information. In this paper, we propose a method for estimating the execution time of an application supported by MATLAB/Simulink on a many-core platform. The proposed method considers operating system (OS) overheads with a real-time OS and Kalray MPPA-256 cluster structure which contains many-core processors. The effectiveness, and the experimental results demonstrate that the proposed method is more accurate than existing methods.
