Rate-Monotonic Scheduler on Zynq (Standalone)

This project implements a Rate-Monotonic (RM) real-time scheduler on the ZedBoard's ARM Cortex-A9 processor. It uses a custom hardware timer and an interrupt-driven scheduler to execute periodic tasks according to their fixed priorities. Tasks with shorter periods receive higher priority. The implementation uses a lightweight standalone environment without an RTOS.

How RM Scheduling Works

1. User enters execution time and period for each task.

2. Tasks are sorted by period (shortest period = highest priority).

3. Hyperperiod is computed using LCM of task periods.

4. At every tick (timer interrupt), the scheduler:

   • Releases tasks whose period has arrived
   • Selects the highest-priority ready task
   • Runs it for one tick
   • Updates remaining execution time
   • Prints the schedule trace

Running the Project

1. Use the given Hardware (.xsa) and build a standalone C application in Vitis.
2. Import the files and setup Run configuration
3. Program the FPGA with the given bitstream and run the application.
4. Provide task parameters through Tera-Term with baud rate of 115200.
