A comparative study for transforming a slow motion system (SMS) into Fast Motion system (FMS) is presented. Priority inversion problem occurs when multiple tasks are running in parallel and request the access of the resource at the same time thereby making the system response slow. In this study an existing SMS running on LPC 1768 board is transformed to FMS using real time concepts -Mutex in μcos that provides inbuilt solution for priority inversion problem by changing the priority of lowest priority task to highest priority momentarily. In the results section, SMs and FMS results are measured which are dependent on different tasks based on priority levels.

Abstract


A comparative study for transforming a slow motion system (SMS) into Fast Motion system (FMS) is presented. Priority inversion problem occurs when multiple tasks are running in parallel and request the access of the resource at the same time thereby making the system response slow. In this study an existing SMS running on LPC 1768 board is transformed to FMS using real time concepts -Mutex in μcos that provides inbuilt solution for priority inversion problem by changing the priority of lowest priority task to highest priority momentarily. In the results section, SMs and FMS results are measured which are dependent on different tasks based on priority levels.
