Hardware scheduler of Real-time Operating System

In this paper, new scheduling algorithms of μC/OS-II real-time operating systems and their hardware implementation are shown. The new scheduling algorithm breakthroughs the limit of the number of total task, and hardware task scheduler was used to select tasks from ready list instead of the original ready table, maintaining the correctness of the software scheduler and improving efficiency of the entire real-time system. This algorithm redesigns in VHDL hardware description language, simulated in ISE 8.2 and implements in FPGA. The new task scheduling algorithm and hardware scheduler decrease the cost of hardware logic and the spending of running time.
