一款非常实用的8051IPcore,本人现在做soc的控制部分就是它。(A very useful 8051IPcore, I now control part of the soc is doing it.)

xilinx应用指南xapp260的中文翻译版本。利用 Xilinx FPGA 和存储器接口生成器简化存储器接口。本白皮书讨论各种存储器接口控制器设计所面临的挑战和 Xilinx 的解决方案，同时也说明如何使用 Xilinx软件工具和经过硬件验证的参考设计来为您自己的应用（从低成本的 DDR SDRAM 应用到像 667 Mb/sDDR2 SDRAM 这样的更高性能接口）设计完整的存储器接口解决方案。(The use of Xilinx FPGA and Memory Interface Generator to simplify memory interface. This white paper discusses the various memory interface controller design challenges facing Warfare and Xilinx solutions, but also explains how to use Xilinx Software tools and hardware-proven reference designs to be for your own With (from low-cost DDR SDRAM applications to such as 667 Mb/s This higher performance DDR2 SDRAM interface) design a complete deposit Storage device interface solution.)

直接数字式频率合成器DDS设计、Verilog。 产生的信号可以是正弦波或方波、三角波、锯齿波等，自选。 采用DDS技术，将所需生成的波形写入ROM中，按照相位累加原理合成任意波形。 此方案得到的波形稳定，精度高，产生波形频率范围大，容易产生高频。 本实验在设计的模块中，包含以下功能： （1）通过 freq 信号输入需要的频率的值； （2）通过 wave_sel 信号选择所需的波形； （3）通过 amp_adj 信号选择波形放大的倍数。(DDS design of direct digital frequency synthesizer, Verilog. The generated signal can be sinusoidal or square wave, triangular wave, sawtooth wave and so on, optional. By using DDS technology, the required waveforms are written into ROM, and arbitrary waveforms are synthesized according to the principle of phase accumulation. The waveform obtained by this scheme is stable, accurate and easy to generate high frequency waveform. This experiment includes the following functions in the designed module: (1) Input the required frequency value through freq signal; (2) Choosing the required waveform by wave_sel signal; (3) Select the multiplier of waveform amplification by amp_adj signal.)
