All kernel operations can only take place using this memory zone , therefore it is the most performance - critical zone 所有的內(nèi)核操作都只能使用這個(gè)內(nèi)存區(qū)域來進(jìn)行,因此這是對(duì)性能至關(guān)重要的區(qū)域。
Data coherence is an important issue in dual - core application . by analysis the system space and task space , the basic principle for application on dual - core is the independence of the task space and the reentrant of the kernel operation 通過對(duì)內(nèi)核的運(yùn)行空間,任務(wù)的運(yùn)行空間進(jìn)行分析,推導(dǎo)出在雙核處理器環(huán)境中保證數(shù)據(jù)一致性的基本條件:任務(wù)運(yùn)行空間的相對(duì)獨(dú)立性和內(nèi)核操作的可重入性。
