Xilinx公司网站下的SDRAM Controller的参考设计，经过验证-Xilinx website of SDRAM Controller reference design, validated

user_logic_VGA_Controller，适合于DE2开发板，把这个文件夹放在工程目录之中，就可以在SOPC里直接添加VGA_Controller IP核了，很方便使用。-user_logic_VGA_Controller. suitable for Dictyophora development board, this folder on the project directory, it can be added directly SOPC Lane VGA_Controller IP core, very convenient to use.

ISE时序约束笔记——Global Timing Constraints，这个文档中详细介绍了如何使用ISE中约束工具和原理，对fpga水平提高有很大帮助(In this file , global timing constraints is introduced very clearly. It can really helps)

能够完美产生数字地面电视（DTMB）的信源的程序。帧头模式为模式一。信道可选择，信号加入频偏，延时，后经滤波器后输出。(Able to produce perfect digital terrestrial television (DTMB) of the source program. Mode is the mode a header. Channels to choose from, the signal adding offset, delay, after the filter output.)
