VIVADO HLS IMAGE 使用文档(vivado image processing example text of zynq)

XAPP585 serdes_1_to_7 and serdes_7_to_1 data

一个用Verilog编写的编帧、解帧及码速匹配的程序，相当经典(Verilog prepared with a series of frames, frames and solutions yards speed matching procedures, rather classic!)

1 由matlab计算FIR数字滤波器的滤波系数； 2 用VHDL语言设计逻辑电路，再通过QUARTUS II 软件，将各个模块的电路封装成期间，在顶层设计中通过连线，完成整个系统。 (matlab VHDL QUARTUS )

verilog 简易频率计的设置，包括整个工程(verilog simple frequency meter settings, including the entire project)

DDS基本原理，详细讲述了DDS基本原理及设计技巧(DDS Basic principle)

? 熟悉IIC协议总线协议，采用IIC总线对图像采集传感器寄存器进行配置，并转换为RGB565格式。 ? 利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。 ? 利用 SDRAM 接口模块的设计，实现了刷新、读写等操作；为提高SDRAM 的读写带宽，均采用突发连续读写数据方式；并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。 ? 利用双线性插值方法实现对图像640×480到1024×768的放大操作。 ? 完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format. Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface. With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA. The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768. Complete the VGA display interface design.)

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)
