And achieve the real - time reconstruction of linux kernel schedule mechanism and small granularity timer by studying the real - time schedule policy edf and rm . meanwhile , the thesis analyses the method of linux schedule mechanism and double kernel mechanism . research and achieve the quicklaunch mechanism in embedded qt , aimed to the demand of embedded system to embedded gui . it is based on mpc5200 environment , so i also describe the embedded linux system about mpc5200 and achieve the logic address and function design of hardware and construct the development environment of software 研究了實(shí)時(shí)調(diào)度策略edf和rm ,結(jié)合linux定時(shí)器原理,實(shí)現(xiàn)了實(shí)時(shí)化改造linux內(nèi)核調(diào)度機(jī)制和細(xì)粒度定時(shí)器,有效提高了linux系統(tǒng)的實(shí)時(shí)性,并詳細(xì)分析了linux調(diào)度策略的實(shí)現(xiàn)和雙內(nèi)核實(shí)時(shí)化改造機(jī)制。針對嵌入式系統(tǒng)對嵌入式gui的要求,分析并實(shí)現(xiàn)了基于嵌入式qt的quicklaunch機(jī)制。本文的研究工作都是基于mpc5200嵌入式系統(tǒng)開發(fā)基礎(chǔ)之上,所以本文又對基于mpc5200的嵌入式linux系統(tǒng)設(shè)計(jì)進(jìn)行了描述,實(shí)現(xiàn)了硬件的邏輯地址和功能設(shè)計(jì)以及軟件開發(fā)環(huán)境的搭建。
This thesis is based on the research of car - navi infromation system which is fund by ministry of information industry ( mii ) . the thesis describes the design of embedded system for mpc5200 , and study function reduce technology , real time improvement technology and quicklaunch mechanism of embedded qt in embedded system development 結(jié)合國家信息產(chǎn)業(yè)部基金項(xiàng)目“車載信息系統(tǒng)” ,本文通過基于嵌入式處理器mpc5200的嵌入式系統(tǒng)設(shè)計(jì),研究了嵌入式linux系統(tǒng)開發(fā)中的函數(shù)級裁剪技術(shù)、 linux實(shí)時(shí)性改進(jìn)技術(shù)和嵌入式qt下的quicklaunch機(jī)制。
