Serial to parallel conversion code

Construction and Experimental Evaluations of User-Centered Power

说明：  this code works with spi and uart interfaces.

这是一个经过测试和使用的VHDL代码，用于将16位二进制输入数据转换为4位BCD。如果您直接驱动显示器而不经过处理器，并且希望显示在主程序中计算的参数，则该程序非常有用。有关转换的戏剧方面，请阅读随附的pdf。

说明：  PID算法用verilog语言实现，实测可用，由三个模块组成(The PID algorithm is implemented in Verilog language. The actual measurement is available. It consists of three modules.)

RISC-V 芯片设计规范,很有参考价值，开源芯片设计必备参考资料，希望对大家有帮助。(The RISC-V Foundation is chartered to standardize and promote the open RISC-V instruction set architecture)

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,图像基本操作,几何变换,直方图,灰度化处理等(System Generator based image processing engineering, multimedia processing FPGA implementation source code, the basic operation of the image, geometric transformations, histogram, gray processing)

一种基于格雷码的异步FIFO设计与实现,8*8位的fifo VHDL 源码-Gray-code based on the Asynchronous FIFO Design and Implementation

小波包分解，重构轴承振动信号，Hilbert包络，FFT进行频谱分析，以获得轴承故障频率。(Wavelet packet decomposition, reconstruction of bearing vibration signal, Hilbert envelope, FFT spectrum analysis to obtain the bearing fault frequencies.)

floating point alignment

在Xilinx开发环境ISE13.2上用MIG产生的DDR3 SDRAM控制器，里面生成了Core，可用于DDR3读写控制(On the Xilinx development environment ISE13.2 generated with MIG DDR3 SDRAM controller, which generates the Core, DDR3 can be used to read and write control)
