周立功的文件系统，在用文件系统的时候非常好用，大家一起研究吧，是个不错的程序-Ligong weeks of the file system, file system with a very good time, let us explore together, be a good procedure

MIPS R4400 用户手册，指令集介绍-The R4000 processor provides complete application software compatibility with the MIPS R2000, R3000, and R6000 processors. Although the MIPS processor architecture has evolved in response to a compromise between software and hardware resources in the computer system, the R4000 processor implements the MIPS ISA for user-mode programs. This guarantees that user programs conforming to the ISA execute on any MIPS hardware implementation.

(U盘MP3)FAT文件系统源码,u盘，mp3下的文件系统，完全兼容fat16，fat32，加上自己的硬盘驱动接口后应该可以使用-(U disk MP3) FAT file system source code, u disks, mp3 under the file system, fully compatible fat16, fat32, coupled with its own hard disk drive interface can be used after

S3C44b0x ARM处理器拷贝程序到RAM中运行-S3C44b0x ARM processor RAM copy of the procedures for running

直流电机调速系统，IAR软件可打开程序，经测试可用。采用闭环调速，PID控制。基于ARM7的LPC21xx系统控制，电路图用PROTEUS仿真开发。都在压缩包内。

configure HID devices like USB mouse with A91SAM7SE CPU. Inlcude initilization for necessary peripherials. Developer can modify this piece code to do their development on HID devices. This is speically for GNU-AT91SAM7SE test code for interfacing HID devices like USB mouse with Atmel ARM7 CPU using GNU, unlike IAR, GNU is free SW which can available to everyone
