The article gives the syntax of the constructors of the scheduler . for the priority inversion happen when high priority thread share with low priority thread a certain resource ^ e . the article puts forward three priority inversion avoidance , priority in _ heritance protocol . priority ceiling emulation protocol , and thread copy protocol 對高優(yōu)先級線程與低優(yōu)先級線程進(jìn)行通信或高優(yōu)先級線程與廣東工業(yè)大學(xué)工程碩士學(xué)位論文低優(yōu)先級線程共享某個(gè)資源時(shí)可能出現(xiàn)的優(yōu)先級逆轉(zhuǎn)問題,本論文討論了三個(gè)避免優(yōu)先級逆轉(zhuǎn)的方法:優(yōu)先級繼承機(jī)制、優(yōu)先級限高機(jī)制、線程復(fù)制機(jī)制。
In the integrated scheduling service , hard periodic tasks are scheduled off - line to meet their real - time requirements , and each soft aperiodic task request is assigned a suitable deadline to enhance the aperiodic responsiveness . scheduling guarantees of hard periodic tasks are preserved through the on - line schedulability analysis . the sharing of critical section resources between the tasks is also considered in the integrated scheduling service ' s schedulability analysis , and bounded blocking for accessing the critical section resource is achieved by introducing the priority ceiling protocol 在該模型中,對硬實(shí)時(shí)周期性任務(wù)集進(jìn)行離線調(diào)度以滿足其可調(diào)度性保證:給動態(tài)到達(dá)的軟實(shí)時(shí)非周期性任務(wù)分配一個(gè)截止期,提高其響應(yīng)性能,同時(shí)通過在線可調(diào)度性分析保證周期性任務(wù)的可調(diào)度性不受影響;集成調(diào)度服務(wù)模型在可調(diào)度性分析中還考慮了任務(wù)之間共享臨界區(qū)資源的情況,采用優(yōu)先級上限協(xié)議對訪問臨界區(qū)引起的阻塞進(jìn)行了定界分析。
