ALU指令

uart documentation, july 17, 2019. the document describes the basics of verilog programming and how to implement them on an fpga device

这是用 vhdl 语言编码的可重构的 fir 滤波器设计 fir 滤波器的实现代码

交织和解交织模块，采用矩阵交织方式，且有两套并行存储器，可以实现连续数据流操作，不会有数据滞留和丢失-Intertwined intertwined reconciliation module, interwoven matrix approach, and has two sets of parallel memory, you can realize continuous data stream operations, will not have data retention and loss

SPI总线硬件描述语言Verilog下的实现，含主模式和从模式的实现，经过仿真验证，可作为一个单独的模块使用(SPI bus under the Verilog hardware description language to achieve with the main mode and slave mode realization, through simulation, can be used as a separate module uses)

VHDL 编写的RAM例子-RAM prepared VHDL example

一个具有“百分秒，秒，分”计时功能的数字跑表，可以实现一个小时以内的精确至百分之一秒的计时。 数字跑表的显示读者可以通过编写数码管显示程序来实现，本训练只给出数字跑表的实现过程。 读者还可以通过增加小时的计时功能，实现完整的跑表功能。-A " percentage of seconds, seconds, minutes," digital stopwatch timer can be achieved within an hour of precision to the hundredth of a second time. Digital stopwatch readers can display the digital display through the preparation of procedures to achieve, given the training is only the realization of the process of digital stopwatch. Readers can also function to increase hours of time to achieve full stopwatch function.

实现拟想要的音乐，基于at89s51单片机的电子琴设计！(To achieve the desired music to be based at89s51 keyboard microcontroller design!)

VHDL BASED DATA COMPRESSION

说明：  数字逻辑实验课第十二次作业，基于Verilog的Clock时钟(Clock based on Verilog)
