K9F1208U0M 的ALE、CLE分別由DSP 的A1 和A0 控制。DSP的低8位數據線直接與閃存的I/O0-I/O7 相連，實現命令、地址和數據的傳輸； DSP的通用I/O口IOA2 接R/B，監測存儲器的工作狀態，當R/ B 處于低電平時,表示有編程、擦除或隨機讀操作正在進行；操作完成后, R/ B 會自動返回高電平。DSP的W E 、R D 分別接FLASH的W E 、R E ， 控制讀、寫操作。CS2接閃存的片選線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.

近年來，隨著多媒體技術、計算機網絡與通信技術的的快速發展，傳統的監控系統也不斷向著新的發展方向進行著不斷的更新與發展。進而隨著嵌入式技術的出現以及人們對降低監控系統成本和提高可靠性的迫切需求，基于嵌入式系統的網絡視頻監控系統將成為新的研發熱點。 本文的目的是把嵌入式技術與計算機網絡技術相結合，構造一個性能穩定且具有較強處理能力的數字化遠程視頻監控系統。該監控系統以嵌入式Linux系統平臺作為服務器端，服務器程序在其上以后臺方式運行，等待監控系統環境中的客戶機使用瀏覽器向其發送訪問請求，實現在局域網乃至Internet網上對攝像頭的遠程控制。 文中把系統設計分為三大部分：系統硬件設計、嵌入式Linux在硬件平臺的實現和系統軟件設計。硬件設計部分首先提出了整個硬件系統的實現方案，接著詳細介紹了S3C2410處理器與存儲器、以太網控制器芯片以及USB和串口的接口電路設計；第二部分詳細敘述了嵌入式Linux在本系統硬件平臺的移植實現及應用程序的開發特點，重點講述了本系統平臺上Linux的引導加載程序Bootloader的設計過程；系統軟件部分首先介紹了USB接口攝像頭驅動在嵌入式Linux下的實現，重點講述了Video4Linux下視頻采集的實現，接著論述了如何實現圖像的JPEG壓縮，最后針對基于B/S模式的網絡通信系統結構，詳細闡述了網絡通信的具體實現過程和方法。 最后在辦公室局域網通過對系統測試，顯示了系統運行結果，實現了利用局域網或Internet網對遠程環境進行監控的功能。
