如今IC设计进入了SOC(System-on-chip)设计时代。SOC是指在单一芯片上集成了微控制器、数字信号处理器、存储器、I/O接口等，可以实现信号采集、转换、存储、处理等功能的芯片。SOC设计是基于IP可重用性的设计过程。现在已有不少公司成功地开发了各种SOC总线规范，以便于IP核的可复用性设计。其中，ARM公司开发的AMBA(Advanced Microcontroller Bus Arehitecture)规范已经成为嵌入式应用的行业标准。嵌入式SOC芯片广泛应用于消费电子产品中，近年来随着彩屏手机、PDA等移动终端的普及，液晶电视等平板显示器件的推广，液晶显示器已经逐渐取代CRT成为主流的显示器件。LCD Driver IC作为液晶显示器的重要部件，需求量也日益增大。嵌入式液晶显示系统的设计是当今SOC设计中不可缺少的部分，而基于AMBA总线规范的LCD显示系统更是具备良好的性能和较大的潜力。 本文提出了一种基于AMBA总线规范的彩色TFT-LCD数字图像显示解决方案，硬件设计上包括APB存储接口模块、LCD控制模块，并用VHDL硬件描述语言进行了功能仿真，采用Mentor公司Modelsim5.8完成了系统功能验证；软件设计上完成了基于SAMSUNG公司S6D0110 TFT-LCD驱动芯片的测试程序的编写和系统测试。本设计不需要掌握TFT-LCD内部构造，复杂的内部驱动原理，只需要掌握AMBA总线规范和LCD的MPU并行接口时序，采用本课题设计出的LCD显示控制模块简单实用，便于推广应用。 本课题基于Xilinx公司的VirtexⅡ FF1152 proto开发平台完成了软件调试，实现了TFT-LCD图像显示。调试结果表明硬件和软件设计正确且取得了较为满意的结果。

直线、圆等图形函数的汇编语言实现 本例所用的绘图函数均采用堆栈的方法传递参数，可以和C语言接口。画点的函数采用直接写显存的方法。为了直接由CPU数据确定像素颜色，而不使用位屏蔽寄存器或置位/重置寄存器，采用了VGA的写模式2方式。直线和圆的算法均采用Bresenham算法实现，其实现过程及堆栈状态均有较详细的说明。最后，将绘图函数用宏封装了起来，便于主程序中调用。当然，主程序中也可直接将参数压入堆栈。其实在较高版本的编译程序中，可以用proto伪指令定义函数原型，再用INVOKE伪指令调用。

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.
