cycloneII Quartus verilog to develop a simple sequential circuit

设计与验证Verilog_实例，经典的HDl书籍，强烈推荐-Design and verification Verilog_ examples Hdl classic books, strongly recommend

a、设计可显示横彩条和纵彩条的VGA彩条信号； b、设计可显示英语字母的VGA彩条信号； c、设计可显示移动彩色斑点的VGA彩条信号； d、设计可实现手动切换a、b、c三个功能.(The design can display VGA color color and color of the longitudinal cross signal. The design can display the VGA color signal of the English alphabet. The design can display the VGA color signal of mobile color spots.)

SPI接口的实现以及对外设的读写操作，其中包扩了几种工作方式，同时可以读取外设的版本号，传输速率可以达到2Mbps-SPI interface implementation, as well as read and write operations on the peripheral, which extended several work packages at the same time can read the version number of peripherals, transfer rate up to 2Mbps

在FPGA硬件上，使用verilog语言编写的一个乘累加器程序。(FPGA hardware, a multiply accumulator verilog language program.)

密码锁verilog源代码，包括四个七段数码管显示模块，设置密码以及输入密码校验模块(Password lock Verilog source code, including four of seven digital tube display module, set the password and password verification module)

support for Coldfire m5441x processors.

并行读写14路串口数据，数据被写入FIFO，在收到读写信号后，SPI发送数据出去(Parallel read and write 14 serial port data, SPI send data)

这是用Verilog HDL写的可调占空比分频控制器，可以挂在Avalon总线上使用-This is written in Verilog HDL with adjustable duty cycle frequency controller, can be hung on the Avalon bus use

基于FPGA开发的11阶半带升余弦FIR滤波器，用在阅读器基带滤波时的抽取滤波器使用，采用verilog语言实现。(Raised cosine FIR filter based FPGA development 11 order of half-band decimation filter used in reader baseband filtering, using verilog language implementation.)
