VxWorks操作系統(tǒng)是一個(gè)功能強(qiáng)大、而且獨(dú)立于處理器的實(shí)時(shí)操作系統(tǒng)，它具有真正微內(nèi)核的相當(dāng)小的層次結(jié)構(gòu)。穩(wěn)定、可靠、高性能的內(nèi)核以及友好的用戶開發(fā)環(huán)境等優(yōu)點(diǎn)使得VxworkS被廣泛應(yīng)用于高精尖以及實(shí)時(shí)性要求極高的領(lǐng)域。文中在分析VxWorks內(nèi)核的多任務(wù)調(diào)度以及相應(yīng)的調(diào)度算法的基礎(chǔ)上，提出了基于優(yōu)先級(jí)的多任務(wù)資源共享問題的解決方案，并介紹了一個(gè)解決優(yōu)先級(jí)倒置的方案實(shí)例。
