[Software Engineering] CRC

Description: 　本文提出一种通用的CRC 并行计算原理及实现方法,适于不同的CRC 生成多项式和不同并行度(如8 位、16 位、及32 位等) ,与目前已采用的查表法比较,不需要存放余数表的高速存储器,减少了时延,且可通过增加并 行度来降低高速数传系统的CRC 运算时钟频率.-In this paper, a universal principle of CRC and implementation of parallel computing methods for generating different CRC polynomial and different degree of parallelism (eg, 8, 16, and 32-bit, etc.), with the current look-up table method has been used in comparison do not store more than a few tables, high-speed memory, reducing latency, and degree of parallelism can be increased to reduce the high-speed data-transmission system clock frequency of the CRC computation.

[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.
