How To Analyze Existing Multitasking Programs Efficiently

When it comes to multi-tasking programs embedded in systems, we know they are an important feature that must be added to most systems in today's world. These give users individual control over each task and activity within a program or source. Truly, multi-tasking is the norm in today's fast-paced world.

While building a multi-tasking program from scratch is a way to develop a clean and integrative design, it's not always possible. Sometimes, fixes and changes must be made to these programs. The way in which a program was built must be understood for any adjustments to be made. This is the challenging part of programming language: working backwards.

There are a few key analytical tools that are essential to understanding multi-tasking programs. A task is defined by the root function of the program in either C or C++. The function in the task is a loop that is continuously coded around the function itself.

Why The Analysis Gets Complicated

A task is generally not considered by itself. Each task interacts with other defined tasks and the overall state of the application through shared variables, synchronization, and a transfer of control. For the best idea of how a multi-tasking program works, you'll need to understand:

  • How the data is being used globally within a system
  • How tasks collaborate together to create a larger whole

If you can get a grasp on the synchronization commands, you will have the basic understanding of how the multi-tasking program is run through interrupting requests, critical definitions, and enabling or disabling regions of the program.
