メモリ保護機能を実装したRTOSに関する提案

Abstract

Recently, as the software of embedded systems is getting larger and more complex, keeping the quality and the reliability of the software high becomes very difficult. One of the approaches to solving this problem is to introduce protection functions to real-time operating system used for embedded systems. We added the access protection function of the kernel object to μITRON4.0. Protection function of embedded system is enabled by managing object in the group. This proposition outlined the protection extension of embedded software and describes the result.
