چکیده (انگلیسی):

RTOS based embedded systems are designed with priority based multiple tasks. Inter task communication and
data corruptions are major constraints in multi-tasking RTOS system. This study we describe about the
solution for these issues with an example Real-time Liquid level control system. Message queue and
Mail box are used to perform inter task communication to improve the task execution time and
performance of the system. Critical section scheduling is used to eliminate the data corruption. In this
application process value monitoring is considered as critical. In critical section the interrupt disable
time is the most important specification of a real time kernel. RTOS is used to keep the interrupt
disable time to a minimum. The algorithm is studied with respect to task execution time and response
of the interrupts. The study also presents the comparative analysis of the system with critical section
and without critical section based on the performance metrics.
