Abstract :
This paper proposes a new approach to realize a very high performance real-time OS using VLSI technology. In order to confirm the effectiveness of this method, the most basic system calls have been designed. According to the evaluation results based on a gate array implementation, hardware portion of system calls can be executed within 4 clocks and the task scheduler can be performed in only 8 clocks simultaneously, which are about 130 to 1880 times faster than software implementation
