基2_8点fft运算的verilog代码

Verilog实现FPGA的VGA塞瑟条纹显示代码，测试完全正确，可以成功的实现功能。

我们在vcs synopsys tools中设计了d触发器，代码是以行为模式编写的；

LPC4357开发板采用ARM的Cortex-M4微控制器LPC4357。内置一个ARM Cortex-M0协处理，CPU运行频率高达204MHz，片内集成1MB Flash和36KB SRAM。开发板采用独立核心板设计，核心板集成64MB SDRAM、128MB NAND-Flash、4MB SPI-Flash。核心板上的摄像头接口可直接连接各种型号的摄像头，两侧160P排针接口引出了除EMC总线外的LPC4357芯片所有功能管脚。 开发板提供丰富的外设接口，包括以太网、液晶屏、摄像头、USB-Host、USB-OTG、SD卡、RS232、RS485、CAN、耳机、麦克风、温度传感器、AD/DA、JTAG仿真器等。此外，开发板提供一个14P扩展接口，包括1路UART、1路SPI、1路I2C、4个IO、3.3V、5V，可以很方便的扩展自己的外围电路。(DS-LPC4357 development board using the Cortex-M4 microcontroller LPC4357 ARM s. A built-in ARM Cortex-M0 co-processor, CPU operating frequency up to 204MHz, 1MB Flash and 136KB SRAM integrated on chip. Development board using an independent core board design, the core board integrates 64MB SDRAM, 128MB NAND-Flash, 4MB SPI-Flash. Camera core board interface can be directly connected to various types of cameras, both sides 160P pin interface leads to the outside of the bus in addition to EMC LPC4357 chip all the functions of the pins. Development board provides a rich set of peripheral interfaces, including Ethernet, LCD screen, camera, USB-Host, USB-OTG, SD card, RS232, RS485, CAN, headphone, microphone, temperature sensor, AD/DA, JTAG emulator, etc. . In addition, the development board provides a 14P expansion interfaces, including one-way UART, 1 road SPI, 1 channel I2C, 4 个 IO, 3.3V, 5V, can easily expand their peripheral circuits.)

调制与解调系统的FPGA设计实现,包括2-ASK调制和解调,2-FSK调制和解调,2-PSK调制和解调,QPSK调制和解调,PPM调制和解调的verilog源代码。(FPGA design implementation of modulation and demodulation system, including 2-ASK modulation and demodulation, 2-FSK modulation and demodulation, 2-PSK modulation and demodulation, QPSK modulation and demodulation, PPM modulation and demodulation verilog source code .)

说明：  控制步进电机转动，正反转，旋转角度完美掌握。很好用，亲测(Control stepping motor rotation, positive and negative rotation, perfect control of rotation angle. Very easy to use, personal test)

先设计序列发生器产生序列：1011010001101010；再设计序列检测器，检测序列发生器产生序列，若检测到信号与预置待测信号相同，则输出“1”，否则输出“0”，并且将检测到的信号的显示出来。(First design sequence generator sequence: 1011010001101010 redesign sequence detector to detect sequence generator sequence, if the same signal is detected with the preset test signal output " 1" , otherwise " 0" , and the detection display signal out.)

DS18B20温度传感器，用verilog语言实现(DS18B20 temperature sensor, with the verilog language)

基于xilinx fpga开发板的音频读写(audio record and play based on xilinx fpga)

说明：  用于FPGA中zynq的温度上报，通过逻辑方式。(It is used to report the temperature of zynq in FPGA by logic)

作为一种古老的接口，支持的分辨率远高于HDMI和DVI，1920分辨率根本不在话下，本设计在QUARTUS下设计，编译，加载运行通过效果良好。
