verilog code for bus controller

说明：  插值滤波器,用于音频解码调制解调,滤波器系数用移位相加实现(Interpolation filter, audio decoder for modulation and demodulation, filter coefficient shift combined with the realization of)

vhdl,十进制加减计数器，输出计数序列信号-vhdl, decimal addition and subtraction counter, the output count sequence signal

64点的 FFT verilog,它是串行计算的，工作频率不到100M，计算速率很高，里面的层次很清晰。(64-point FFT verilog serial computing, the operating frequency of less than 100M, the calculated rate is high, the level inside is very clear.)

本文参考了Xilinx 官方文档UG873，“System Design Using Processing System High Performance Slave Port”。主要实现了PL 中AXI CDMA IP 与PS 部分HP64bit 从接口集成。 本例中AXI CDMA 部分扮演主机，从PS 部分DDR 系统内存中源缓冲区拷贝一列数据到目 的缓冲区。可以分别采用裸机工程和基于Linux 的应用软件来实现功能。(This reference to the official document Xilinx UG873, " System Design Using Processing System High Performance Slave Port" . The main achievement of the PL in AXI CDMA IP interface integration with PS part HP64bit. In this example AXI CDMA part to play host, a copy of a column of data into the destination buffer section PS source DDR system memory buffer. Can respectively bare engineering and Linux-based applications to achieve functional.)

本例是一个6层电梯的控制系统,VHDL原程序,状态机,控制器-This case is a 6-storey elevator control system, VHDL original procedures, state machine, controller

说明：  FFT 1024 point, in 10 state

这是用VHDL实现的8位加法器，对新手有点帮助。-This is achieved using VHDL adder 8, a little help to novices.

matlab随即图设计程序，应该比较有用，希望能申请会员成功吧。。(matlab then drawing design program)

802.1as gptp标准包解析verilog模块。用于实现EAVB协议的重要部分。(802.1as gptp verilog module, part of EAVB procotol)
