1. Multiple Processors Real- time Operating System IEOS proposal R00921080 蔡偉哲 R00921072 李俊融

2. Introduction In modern mobile industry, there are more and more cores in CHIP Lack a multicore real time OS on multiprocessor.

3. Motivation Except the critical process, there exist other important processes in OS. We want to use multicore so that we reduce the cost Example : Example : Missile defense system Compute missile track and detect other missile

4. Why Multiple processors Technical bottleneck Power consumption P=CV 2 F, where C is capacitance, V is voltage and F is clock frequency
