【摘要】：“龍芯”是中國(guó)科學(xué)院計(jì)算所自主研發(fā)的基于MIPS架構(gòu)的高性能通用CPU,在2002年研制成功“龍芯1號(hào)”處理器芯片后,近些年分別研制成功“龍芯2B”、“龍芯2C”、“龍芯2E"、“龍芯2F”、“龍芯3A”等一系列產(chǎn)品。江蘇中科夢(mèng)蘭電子科技有限公司是龍芯的產(chǎn)業(yè)基地和龍頭企業(yè),致力于基于龍芯CPU的產(chǎn)品研發(fā)和市場(chǎng)化推廣,用自主創(chuàng)新技術(shù)打造行業(yè)信息化整體解決方案。目前已開發(fā)研制了福瓏、逸瓏和靈瓏等幾大系列產(chǎn)品,并基于這些產(chǎn)品打造了農(nóng)村信息化、教育信息化等多種解決方案。 U-Boot,全稱Universal BootLoader,是一款從8xxROM、PPCBoot、ARMBoot項(xiàng)目逐步發(fā)展演化而來嵌入式固件系統(tǒng)。其開發(fā)遵循GPL協(xié)議,對(duì)所有用戶開放源代碼。U-Boot系統(tǒng)還在不斷的開發(fā)過程中,到目前的版本已經(jīng)能夠支持PowerPC、ARM、X86、MIPS、68k及MicroBlaze等多種架構(gòu)的處理器。該系統(tǒng)在嵌入式開發(fā)領(lǐng)域被廣泛應(yīng)用。 本文通過研究龍芯產(chǎn)品和U-Boot系統(tǒng)的特點(diǎn),提出將U-Boot作為固件(firmware)系統(tǒng)移植到龍芯平臺(tái)的實(shí)施方案,本文分析了U-Boot的系統(tǒng)結(jié)構(gòu)特點(diǎn)、啟動(dòng)流程、Loongson-2F CPU初始化相關(guān)的指令集及基于該CPU的Yeeloong8089筆記本的主板結(jié)構(gòu)和相關(guān)設(shè)備,說明了系統(tǒng)移植的方法,論述了相關(guān)的開發(fā)平臺(tái)以及應(yīng)用技術(shù),描述了系統(tǒng)性能指標(biāo)、功能特性和運(yùn)行環(huán)境。并通過運(yùn)行實(shí)例驗(yàn)證了所述技術(shù)方案的正確性和有效性。
[Abstract]:"Dragon Son" is a high performance universal CPU based on MIPS architecture developed by the Institute of Computing of the Chinese Academy of Sciences. After the successful development of the "Godson 1" processor chip in 2002, in recent years, "Godson 2B" and "Dragon Son 2C" have been developed respectively. "Longson 2 E", "long son 2 F", "long son 3A" and a series of products. Jiangsu Zhongke Meng Lan Electronic Technology Co., Ltd. is the industrial base and leading enterprise of Longson. It is committed to the R & D and marketization of products based on Godson CPU, and uses independent innovation technology to create the overall solution of industry informatization. At present, several series of products, such as Fu long, Yi long and Ling long, have been developed, and based on these products, rural informatization has been built. U-Boot (Universal Boot Loader) is an embedded firmware system developed from 8xxROM PPC Boot ARMBoot project. Its development follows the GPL protocol, and the open source .U-Boot system for all users is still in the process of continuous development. So far, the current version has been able to support a variety of processors such as PowerPC ARMU X86 MIPST 68k and MicroBlaze. The system is widely used in the field of embedded development. By studying the characteristics of the Godson products and the U-Boot system, this paper proposes a scheme of transplanting U-Boot as firmware system to the Godson platform, and analyzes the structural characteristics of U-Boot system. The instruction set related to the initialization of Loongson-2F CPU and the main board structure and related equipment of the Yeeloong8089 notebook based on this CPU are introduced in this paper. The method of system porting is explained, the development platform and application technology are discussed, and the performance index of the system is described. Functional features and operating environment. The correctness and validity of the technical scheme are verified by a running example.
