近年來, 嵌入式系統越來越強調大量運算、多媒體的整合, 以及穩固的通訊
功能, 因此單核心處理器已不敷需求。目前普遍的解決方法是透過多核心處理器
來滿足大量運算的需求; 嵌入式系統中, 多核心處理器的使用越來越普遍,其低
功率、低耗能和高效能的特性完全符合嵌入式系統的需求。μC/OS-II是一套簡單
而有效率的即時作業系統, 本身支援多工執行(multitask), 但不支援對稱式多核
心x86處理器(SMP)。本論文主要目的是將μC/OS-II移植到x86多核心處理器平台,
我們開發了獨立的多核心處理器程式模組,並修改μC/OS-II 核心的排程器, 使μ
C/OS-II 可運作於對稱式多核心處理器平台, 並有效地利用每個處理器, 以達到
系統的最大效能。
In recent years, the increasing demands on computational performance make uniprocessor infeasible for embedded systems. With low power, low energy consumption, and high performance features, multiprocessor are widely adopted in embedded systems. μC/OS-II is a simple and efficient real-time operating system and supports multitasking. However, it is designed for uniprocessor platform and does not support Symmetric MultiProcessing (SMP). The major goal of our research is porting μC/OS-II to x86 multi-core platform. We develop an independent multi-core module and modify the scheduler in μC/OS-II kernel to make μC/OS-II applicable in multiprocessor platform such that the capability of each processor can be fully utilized!
