Abstract:
The design of real-time embedded
systems involves a constant trade-off
between meeting real-time design goals
and operating within power and energy
budgets. Nowadays, embedded systems are
commonly applied in automotive industry.
Some of applications require strict time
response, and others need to be exactly
scheduled to execute a period task. All of
these are called time-sensitive applications.
Measuring and evaluating time parameters
of an embedded system for time-sensitive
applications is very necessary for
developers to guarantee that it works
functionally.
By managing the interaction with
external systems through effective use of
interrupts can dramatically improve system
efficiency and the use of processing
resources. An interrupt handler is part of
an embedded system of real-time operating
system (RTOS). An interrupt handler is to
handle the tasks according to the priority.
This paper explores how to handle
interrupt among the priority based periodic
tasks (independent threads) by using
architectural features of H8/3069 FZTAT
™ microcontrollers.
