verilog code of counter with clock divider for fpga implementation

这是一个16位乘法器Verilog程序，包括有符号位和无符号位乘法器(This is a 16-bit multiplier Verilog program, including the sign bit and no sign bit multiplier)

基于FPGA的神经网络硬件实现中的关键问题研究，适合用fpga研究神经网络的工程人员参考(FPGA-based hardware implementation of neural networks in the study of key issues for research with neural networks fpga reference works)

说明：  由忆阻器机制设计蕴含逻辑，内含testbench仿真文件(Design implied logic by memristor mechanism, including testbench simulation file)

该程序用来实现电话计时以算取费用，比较简单(telephone cost metering verilog code)

fpga实现的IIC通信的例程，注释很详细(fpga implementation of serial communication routines, comments in great detail)

•TheI²C （使用电路） 一般被称为"两个 wireinterface"。•ThisI²C 接口将创建主设备和从设备之间的通信。•Theinterface 将读取主人的命令，并发送相应的对主人。••Ourinterface 设计包括读和写操作，将能交流掌握并通过 I2C 奴隶。

This is counter with T_FF.

常用的锁相环技术，此程序是我在设计高频电路中运用的，具体见程序，经调试无问题(Commonly used phase-locked loop technology, this program is in the design I used in high-frequency circuits, see the specific procedures, no problem by debugging)

说明：  我自己当初用来求解arctan 暂时没有搞成ip形式 搞好了还要传git 这个代码还没有搞好，因为急需要下载东西 如果感兴趣可以联系我 邮件(this is a not full wrappered code very crude use chebyshev to caculate arctan function i m urgent to download a model from pudn so i do this.)

用Verilog语言实现4位二进制同步计数器的功能(Write a program in Verilog language to implement the fouction of Four binary synchronous counters.)
