Abstract

This paper presents our experience of using a small real time executive tinyexec as a teaching tool in an operating system class. We present the details of the tinyexec that include a state transition diagram, pseudocode, and some sample exercises that can enhance students understanding of operating systems concepts. tinyexec has 300 lines of code and works in a stand-alone or a DOS or WINDOWS environment. It can be easily modified and ported. Our experience shows that the small size of tinyexec is an advantage over many other systems like LINUX-RT and can result in extensive experimentation and it is an excellent source to supplement the operating systems concepts with a real executive.
