Real-Time Operating System (RTOS) is a software component that is able to rapidly switches the tasks, making the user have the impression of running multiple programs simultaneously on a single processor. An RTOS provides a highly deterministic reaction and hard real time response to the external events. Because of hard real time response, it is a must for a system to meet its deadline or an unacceptable damage may occur. So, development of an RTOS for RISC32 processor plays an important role to improve its performance. RISC32 was developed by a group of FICT programmer and the processor is involved in this project as academic purpose. Up to the current stage, the processor supported Interrupt Service Routine (ISR) and exception handler. To improve the processor, an RTOS software code written in C programming language is used to improve the processor performance. To master the RTOS code, FreeRTOS is used as a reference and guidelines to assist us in creating an RTOS code for this project. The RTOS code is divided into few partitions storing in individual file to help the reader to understand the code easily. The code obtained from FreeRTOS was modified in order to port the processor used in this project. Therefore, we expect that the processor is able to switch the task rapidly and must meet the deadline after the implementation of the compiled code.
