Abstract :
Proposed an implementation framework of single chip dual-kernel smart phone OS based on virtual machine and constructed a smart phone OS including virtual machine, the real-time kernel Nucleus and standard Linux kernel. Testing on a demo board, the maximum interrupt response time and the maximum task preemption latency respectively was 16.90 μs and 121.00 μs, which reach the requirement of real-time performance.
