VHDL

说明：  用verilog语言实现计算反正切函数，在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程，基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真，并取其中间的I和Q支路做为verilog文件的输入，并将其借条输出与MATLAB实际解调输出作比较。 鉴相器的设计基于CORDIC算法，其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值，并不需要绝对的值，所以并没有给予加权，需要的同学可以自己加上。(Calculated using verilog language arc tangent function, the software radio demodulation PM/FM is particularly used frequently. From the archive is modelsim project, based on 6.5c, inside the PM contains a complete demodulation process of wave generation and simulation matlab file, and whichever is the middle of the I and Q branch verilog file as input, and its IOU demodulated output and actual output of MATLAB for comparison. Phase detector design is based on CORDIC algorithm, its accuracy depends on the iteration depth. As the practical application of engineering demodulated atan value only and does not need absolute value, and there is no weight given to the need of the students can add their own.)

本文参考了Xilinx 官方文档UG873，“System Design Using Processing System High Performance Slave Port”。主要实现了PL 中AXI CDMA IP 与PS 部分HP64bit 从接口集成。 本例中AXI CDMA 部分扮演主机，从PS 部分DDR 系统内存中源缓冲区拷贝一列数据到目 的缓冲区。可以分别采用裸机工程和基于Linux 的应用软件来实现功能。(This reference to the official document Xilinx UG873, " System Design Using Processing System High Performance Slave Port" . The main achievement of the PL in AXI CDMA IP interface integration with PS part HP64bit. In this example AXI CDMA part to play host, a copy of a column of data into the destination buffer section PS source DDR system memory buffer. Can respectively bare engineering and Linux-based applications to achieve functional.)

说明：  基于OV5640摄像头的视频图像传输存储以及读取。供大家参考。(Video image transmission, storage and reading based on ov5640 camera. For your reference.)

用组合逻辑实现循环除法器。稳定、安全、可靠。(Combinational logic loop divider. Stable, secure, and reliable.)

RAM存储器： 设定16 个8 位存储单元。如果read= 1 则dataout

说明：  FPGA控制外边led，并实现跑马灯等多种效果，用户可以自行控制(FPGA control outside led)
