异步FIFO的verilog代码

vhdl语言，国外教材，数字信号处理算法(vhdl language, foreign materials, digital signal processing algorithms)

此vhdl程序实现了在FPGA上构建UART通信串口。分为两部分，UART的发送端transfer和接收端receiver。需要外部根据需求提供波特率时钟。(This program implements the building vhdl UART serial interface on the FPGA. Divided into two parts, UART transfer sender and receiver receiver. Required to provide the baud clock external demand.)

初学学习verilog的经验，可以帮助新手以正确的思维方式，学习方法学习。(Verilog learning experience)

非常好的verilog书 国际牛人写的 适合各个阶段学习的人(Very good Verilog books were written in the international cattle suitable for the various stages of learning)

ahbsram contains all codes of sram

一个自定义的内存，存储了一个链表，通过数据通路访问内存，读取数据，计算链表累加和，数据通路的控制器由一个有限状态机组成，实现了多状态下控制信号的产生，计算的结果回写到内存制定单元。整个过程介绍了有限状态机的设计以及数据通路控制的基本原理

说明：  在FPGA板卡上面，通过单个按键实现串口的发送功能，带仿真需要自行修改一下工程配置(On the FPGA board, the sending function of the serial port is realized by a single key, and the engineering configuration needs to be modified by the simulation)

本例介绍直接合成带阻滤波器的方法，n阶滤波器能实现n个传输零点(A direct synthesis technique of a new class of bandstop coupled resonator elliptic filters is presented. Two different coupling schemes, which both include source–load coupling are used. The first coupling and routing scheme is the standard folded structure used in implementing bandpass elliptic filters with transmission zeros using resonators.)
