Research on Tailoring Technology of Array CCD Aerial Camera Linux System

In view of the actual demand of operating system of the air plane array CCD camera, and combining with the hardware resources of the PC104 bus structure, Linux system adopted in CCD camera is cut practically, which based on the tailoring method adopting the combination of coarse-grained and fine-grained to enhance the Linux kernel preemption, improve the scheduling strategy of Linux kernel scheduler, to build a embedded system with the strong implementation capacity. The system startup and task of the response performance test in different environment shows that the cut systems is stable, reliable, and can achieve the startup time less than 5s, the performance of the task response time less than 20 millisecond.
