Experiences with Memory Access Issues in RTOS

Free registration required

Executive Summary

Based on the architecture of the operating system as well as the nature of the software defect. Memory access issues often encountered on Real-Timer Operating Systems [RTOSI may be either very simple or a cryptic puzzle. This paper presents sonic of the memory access issues often noticed on bsj1iipler models of soft Real-Time Operating Systems. Discussed with each class of issue are the typical software defects responsible for the same. Some efficient debugging methods/techniques for such issues have also been explained. Often a Real-Time Operating System [RTOS] depends on virtual memory mechanism to provide private memory regions for tasks. This mechanism of protection would be beneficial as long as memory shared between tasks is within acceptable limits.
