对嵌入式实时操作系统进行了深入的研究。对当前UCLINUX操作系统上增强实时性 的不同方案进行了详细的分析和比较，提出了现存方案的优缺点。其后分析了 UC／OS―II的结构和特点，改造了UC／OS．II的实时内核，将其移植到UCLINIⅨ作为专 门处理实时进程的的内核(X2内核)，从而改良UCLINUX的实时性。-For embedded real-time operating system, conducted in-depth study. On the current UCLINUX enhanced real-time operating systems of different options for a detailed analysis and comparison, presented the advantages and disadvantages of the existing program. Subsequent analysis of UC/OS-II structure and characteristics of the transformation of the UC/OS. II, real-time kernel, be transplanted to UCLINI Ⅸ as to deal specifically with real-time process, the kernel (X2 core), thereby improving UCLINUX in real time.
