如今IC設計進入了SOC(System-on-chip)設計時代。SOC是指在單一芯片上集成了微控制器、數字信號處理器、存儲器、I/O接口等，可以實現信號采集、轉換、存儲、處理等功能的芯片。SOC設計是基于IP可重用性的設計過程。現在已有不少公司成功地開發了各種SOC總線規范，以便于IP核的可復用性設計。其中，ARM公司開發的AMBA(Advanced Microcontroller Bus Arehitecture)規范已經成為嵌入式應用的行業標準。嵌入式SOC芯片廣泛應用于消費電子產品中，近年來隨著彩屏手機、PDA等移動終端的普及，液晶電視等平板顯示器件的推廣，液晶顯示器已經逐漸取代CRT成為主流的顯示器件。LCD Driver IC作為液晶顯示器的重要部件，需求量也日益增大。嵌入式液晶顯示系統的設計是當今SOC設計中不可缺少的部分，而基于AMBA總線規范的LCD顯示系統更是具備良好的性能和較大的潛力。 本文提出了一種基于AMBA總線規范的彩色TFT-LCD數字圖像顯示解決方案，硬件設計上包括APB存儲接口模塊、LCD控制模塊，并用VHDL硬件描述語言進行了功能仿真，采用Mentor公司Modelsim5.8完成了系統功能驗證；軟件設計上完成了基于SAMSUNG公司S6D0110 TFT-LCD驅動芯片的測試程序的編寫和系統測試。本設計不需要掌握TFT-LCD內部構造，復雜的內部驅動原理，只需要掌握AMBA總線規范和LCD的MPU并行接口時序，采用本課題設計出的LCD顯示控制模塊簡單實用，便于推廣應用。 本課題基于Xilinx公司的VirtexⅡ FF1152 proto開發平臺完成了軟件調試，實現了TFT-LCD圖像顯示。調試結果表明硬件和軟件設計正確且取得了較為滿意的結果。

直線、圓等圖形函數的匯編語言實現 本例所用的繪圖函數均采用堆棧的方法傳遞參數，可以和C語言接口。畫點的函數采用直接寫顯存的方法。為了直接由CPU數據確定像素顏色，而不使用位屏蔽寄存器或置位/重置寄存器，采用了VGA的寫模式2方式。直線和圓的算法均采用Bresenham算法實現，其實現過程及堆棧狀態均有較詳細的說明。最后，將繪圖函數用宏封裝了起來，便于主程序中調用。當然，主程序中也可直接將參數壓入堆棧。其實在較高版本的編譯程序中，可以用proto偽指令定義函數原型，再用INVOKE偽指令調用。

SimpliciTI™ -1.0.3.exe for CC11xx and CC25xx SimpliciTI is a simple low-power RF network protocol aimed at small (<256) RF networks. Such networks typically contain battery operated devices which require long battery life, low data rate and low duty cycle and have a limited number of nodes talking directly to each other or through an access point or range extenders. Access point and range extenders are not required but provide extra functionality such as store and forward messages. With SimpliciTI the MCU resource requirements are minimal which results in the low system cost.

This thesis is about wireless communication in shared radio spectrum. Its origin and motivation is ideally represented by the two quotations from above. In this thesis, the support of Quality-of-Service (QoS) in cognitive radio networks is analyzed. New approaches to distributed coordination of cognitive radios are developed in different spectrum sharing scenarios. The Wireless Local Area Network (WLAN) 802.11 proto- col of the Institute of Electrical and Electronics Engineers (IEEE) (IEEE, 2003) with its enhancement for QoS support (IEEE, 2005d) is taken as basis. The Medium Access Control (MAC) of 801.11(e) is modified to realize flexible and dynamic spectrum assignment within a liberalized regulation framework.
