  1. The paper carefully describes important technology relevant of the new scheme. the thinking and purpose of realizing software interrupt emulation technology is explained in detail, and the concrete tactics of implementing the refined timer in two styles is set forth. the paper discusses two real time schedule arithmetic adopted by real time kernel such as rate monotonic analysis arithmetic and earlier deadline first arithmetic, and the resolvent of preventing priority inversion is made out

    文章對新實現方案的重要相關技術做了細致的論述,其中,詳細說明了軟體中斷模擬技術的實現思路和目的;對兩種模式下( periodic 、 oneshot )細粒度定時器的具體實現策略做了闡述;對實時內核所採用的兩種實時調度演算法:速率單調性分析演算法和最早期限優先演算法進行了描述,並提出了防止優先級反轉的解決方法。
  2. In the scheme, not only the rtlinux ' s double kernel structure and its virtual interrupt are adopted, which make the standard linux process as the lowest priority one in the real - time kernel, but also the 8254 is set to work in the one - shot model by using the kurt ' s utime package, which improves the clock frequency of the os and reduces the cpu ' s extra burden

    這種新的實時化方案利用了rtlinux的雙內核體系結構和中斷虛擬機技術,將標準linux進程作為實時內核的一個優先級最低的任務進行調度;同時還利用了kurt中utime軟體包將定時/計數器8254置為one - shot工作模式,從而既提高了操作系統的時鐘頻率,又解決了cpu額外負擔過重的問題。
