摘　　要：随着我国科技实力的不断增强,一些国家开始对中国采取措施,对出口中国的芯片进行加税加价,这使得中国众多企业和公司面临着严峻的挑战。我们要想摆脱困境,我们就要拥有自己的芯片,制造属于我们的中国"芯"。龙芯2K1000是我国今年刚刚研发的一款嵌入式芯片,龙芯2K1000处理器是面向网络安全领域及移动智能终端领域的双核处理器芯片。龙芯2K1000处理器集成两个GS264处理器核,芯片外围接口包括两路PCIE2.0、一路SATA2.0、4路USB2.0、两路DVO、64位DDR2/3及其它多种接口,可以满足中低端网络安全应用领域需求,并为其扩展应用提供相应接口。对于一款嵌入式芯片来说,要想使用它,首先要掌握它的启动方法,其主要分为三个步骤:1、bootloader的制作;2、文件系统的制作;3、内核系统的安装。论文主要研究基于龙芯2K1000龙芯派的内核启动。With the continuous enhancement of science and technology in China,some countries have begun to take measures by increasing taxes and prices on chips exported to China,which makes many Chinese enterprises and companies face severe challenges. If we want to get out of this dilemma,we have to possess our own chips and make our own Chinese ＂core＂. Loongson 2 K1000 is an embedded chip just developed in China this year. Loongson 2 K1000 processor is a dual-core processor chip for network security and mobile intelligent terminal. It integrates two GS264 processor cores,and the peripheral interfaces include two PCIE2.0,one SATA 2.0,four USB 2.0,two DV0 s,64-bit DDR2/3 and many other interfaces,which can meet the needs of low-end network security applications and provide corresponding interfaces for its extended applications. For an embedded chip,the start-up way should be grasped before use it. The way of start-up is divided into three steps：first,the production of bootloader;second,the production of the file system;third,the installation of the kernel system. The article mainly introduces the core startup based on Loongson 2 K1000 Loongson core pie.
