8051 verilog achieve, enclosing testbench, c language debugging procedures

FFT程序，此程序虽然耗逻辑资源很大，但是在接受数据后的第7个时钟沿就可以输出FFT变换后的数据，对要求时延较低的系统可以考虑-FFT procedure, this procedure should not consume a lot of logic resources, but the data in the first seven clock can be output along the FFT transformed data, the requirements of time-delay system can be considered lower

自己去年做的实训项目，基于FPGA的VHDL的电子琴，可实现自动演奏与手动演奏，手动演奏是用PS2键盘听过按键来实现电子琴的发音，并且用VGA显示音符与音键，本设计采用模块化设计，底层使用代码，通过例化成原理图，最终在底层实现原理图之间的连接。

该源码可基于FPGA设置多分辨率的HDMI显示，且其包含了完整的时序和端口、地址映射，可以很方便的将其移植(The source code can be set based on FPGA multi-resolution HDMI display, and it includes a complete timing and port, address mapping, it can be easily transplanted)

本文介绍了一个使用 VHDL 描述计数器的设计、综合、仿真的全过程，作为我这一段 时间自学 FPGA/CPLD 的总结，如果有什么不正确的地方，敬请各位不幸看到这篇文章的 大侠们指正，在此表示感谢。当然，这是一个非常简单的时序逻辑电路实例，主要是详细 描述了一些软件的使用方法。文章中涉及的软件有Synplicity 公司出品的Synplify Pro 7.7.1； Altera 公司出品的 Quartus II 4.2；Mentor Graphics 公司出品的 ModelSim SE 6.0。 -This article describes a VHDL description of the use of counter design, synthesis, simulation of the entire process, this time as my self-FPGA/CPLD summary, if what has not the right place, please see this article that, unfortunately, the heroes They correct me, wish to express my gratitude. Of course, this is a very simple example of sequential logic circuit is mainly a detailed description of a number of software usage. Article involved in the software company has produced Synplicity

设计制作一个检测4*4矩阵键盘的按键编码的实验，把实际按键的键值的八位编码先转换成从0000—1111的编码，再译成数码管能识别的八位编码，在数码管动态显示时，4*4矩阵键盘的第一行对应00—03，第二行对应04—07，第三行08—11，第四行对应12—15。(Design a 4* 4 matrix keyboard key coding experiments to detect the key the actual key octet coded first convert from 0000-1111 encoding, and then translated into digital tube to identify the eight coding, digital tube dynamic display, the first line of the 4* 4 matrix keyboard corresponding to 00-03, the second line corresponds to 04-07, the third line of 08-11, the fourth line corresponds to 12-15.)
