K9F1208U0M 的ALE、CLE分别由DSP 的A1 和A0 控制。DSP的低8位数据线直接与闪存的I/O0-I/O7 相连，实现命令、地址和数据的传输； DSP的通用I/O口IOA2 接R/B，监测存储器的工作状态，当R/ B 处于低电平时,表示有编程、擦除或随机读操作正在进行；操作完成后, R/ B 会自动返回高电平。DSP的W E 、R D 分别接FLASH的W E 、R E ， 控制读、写操作。CS2接闪存的片选线CE。

Atheros Communications AR6001 WLAN Driver for SDIO installation Read Me March 26,2007 (based on k14 fw1.1) Windows CE Embedded CE 6.0 driver installation. 1. Unzip the installation file onto your system (called installation directory below) 2. Create an OS design or open an existing OS design in Platform Builder 6.0. a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items). b. Run image size should be set to allow greater than 32MB. 3. a. From the Project menu select Add Existing Subproject... b. select AR6K_DRV.pbxml c. select open This should create a subproject within your OS Design project for the AR6K_DRV driver. 4. Build the solution.

近年来，随着多媒体技术、计算机网络与通信技术的的快速发展，传统的监控系统也不断向着新的发展方向进行着不断的更新与发展。进而随着嵌入式技术的出现以及人们对降低监控系统成本和提高可靠性的迫切需求，基于嵌入式系统的网络视频监控系统将成为新的研发热点。 本文的目的是把嵌入式技术与计算机网络技术相结合，构造一个性能稳定且具有较强处理能力的数字化远程视频监控系统。该监控系统以嵌入式Linux系统平台作为服务器端，服务器程序在其上以后台方式运行，等待监控系统环境中的客户机使用浏览器向其发送访问请求，实现在局域网乃至Internet网上对摄像头的远程控制。 文中把系统设计分为三大部分：系统硬件设计、嵌入式Linux在硬件平台的实现和系统软件设计。硬件设计部分首先提出了整个硬件系统的实现方案，接着详细介绍了S3C2410处理器与存储器、以太网控制器芯片以及USB和串口的接口电路设计；第二部分详细叙述了嵌入式Linux在本系统硬件平台的移植实现及应用程序的开发特点，重点讲述了本系统平台上Linux的引导加载程序Bootloader的设计过程；系统软件部分首先介绍了USB接口摄像头驱动在嵌入式Linux下的实现，重点讲述了Video4Linux下视频采集的实现，接着论述了如何实现图像的JPEG压缩，最后针对基于B/S模式的网络通信系统结构，详细阐述了网络通信的具体实现过程和方法。 最后在办公室局域网通过对系统测试，显示了系统运行结果，实现了利用局域网或Internet网对远程环境进行监控的功能。
