[VHDL-FPGA-Verilog] fpga.fifo

Description: 异步FIFO是用来适配不同时钟域之间的相位差和频率飘移的重要模块。本文设计的异步FIFO采用了格雷（GRAY）变换技术和双端口RAM实现了不同时钟域之间的数据无损传输。该结构利用了GRAY变换的特点，使得整个系统可靠性高和抗干扰能力强，系统可以工作在读写时钟频率漂移达到正负300PPM的恶劣环境。并且由于采用了模块化结构，使得系统具有良好的可扩充性。-Asynchronous FIFO is an important module which always used to absorb the phase and frequency offset between different clock domain in communication area .In this paper, an FIFO module is designed using Gray convert technology and dual-port ram , which realizing scatheless transmit between different clock domain. The advances of Gray (Only one bit changes between neighboring two clock ) improves the reliability and anti-jamming capability of the system. And the system can work normally in the bad condition which the phase and frequency offset target to 300PPM. It is proved by work that the FIFO module can fulfill the demands of real-time of data transmitting system, and the module is powerful enough for more data process in the future.

[Video Capture] camera_up

Description: Camera Interface模块是视频输入转换存储模块。该模块一端接通用的video camera设备，另一端接AHB总线。实现了将Camera捕捉到的数据进行转换、并通过DMA存储到memory中。该IP支持ITU-R BT 601/656 8-bit 模式。支持YCbCr, RGB格式输入。可以将camera产生的YCbCr信号转换成24bit RGB 信号，然后下采样生成16bit RGB 5：6：5的LCD能直接读取显示的数据。该设备支持图像的镜像和翻转，以便适应手持式设备在移动环境中图像的捕捉。可变的同步信号极性使得可以兼容各种摄像头外设。Camera Interface兼容AMBA规范， AHB SLAVE接口，用于读取软件配置数据和设置数据存放地址和1帧数据占用的空间。-The Camera IP Core is small and flexible video data coverter. It is connected to a typical video camera ICs with 8-bit digital video data, Horizontal synchronization and Vertical synchronization signals. The core is connected through FIFO to a WISHBONE bus on the other side. Both sides of the core can operate at fully asynchronous clock frequencies. The Camera IP Core convertes 4:2:2 YCbCr video data (sometimes called YUV, but not totally the same Y is the same, while Cb and Cr are U and V multiplied by a constant) to a 24-bit RGB. 24-bit or 16-bit RGB data, downsampled from 24-bit RGB, is then sent to the system (video) memory, however conversion can also be by-passed. Interrupt can be generated after frame-buffer in system (video) memory is filled up or after setable number of horizontal lines written to frame-buffer.

[OS Develop] program

Description: 设计实现4bit FIFO, 数据深度为8， 产生满， 空状态标志-The diagram of FIFO is shown in figure 1. The FIFO consists of two component: FIFO control logic and RAM. The control logic generates the address (ADD) and write enable (WE) to the RAM so that the first data word written into the RAM is also the first data word retrieved from the RAM. As shown in the Figure 1, the RAM is implemented to operate as a FIFO. The RAM is assumed to have separate data inputs and outputs, an N-bit address bus (ADD) and an active high write enable (WE). The inputs to FIFO/Stack include PUSH, POP, INIT (all active high) in addition to the rising edge triggered CLK input. The FIFO logic will not only supply the address and write enable to the RAM, but will also supply active high flags for FULL, EMPTY, NOPOP, and NOPUSH conditions.
