Teaching Task Scheduling in Real Time System Course

Teaching Task scheduling in Real Time System course Subramaniam Ganesan,

Objectives of the Real-Time Systems course are normally written to reflect what we expect the students to learn from the course. We make sure that it is possible to assess the objectives at the end by internal or external expert. We need to make sure the teaching activities and feedback from the students are synchronized with the objectives. It is also necessary to emphasize active learning instead of passive learning.

One of the objectives of this course is: ´Know the various task assignment and scheduling methods. For example RM and EDF scheduling”

We describe here a set of experiments that use a low cost ARM microprocessor board and MDK-ARM Keil development tool. Keil MDK Version 5 is the latest release complete software development environment for a wide range of ARM, Cortex-M, and Cortex-R based microcontroller devices. MDK includes the µVision IDE/Debugger, ARM C/C++ Compiler, and essential middleware components. It's easy to learn and use. A number of experiments to learn real-time task scheduling concepts are explained in the full paper. A number of useful information available from ARM University program web site is also pointed out. A list of low cost boards that can be used for these experiments and use of an example board from ST microelectronics are also provided. Use of Real-Time scheduling in automotive embedded system applications is described and justifies the importance of our teaching techniques.
