Description: 基于高速数字信号处理器(DSP) 和大规模现场可编程门阵列( FPGA) ,成功地研制了小型
化、低功耗的实时视频采集、处理和显示平台. 其中的DSP 负责图像处理,其外围的全部数字逻辑功能都集成在一片FPGA 内,包括高速视频流FIFO、同步时序产生与控制、接口逻辑转换和对视频编/ 解码器进行设置的I2 C 控制核等. 通过增大FIFO 位宽、提高传输带宽,降低了占用EMIF 总线的时间 利用数字延迟锁相环逻辑,提高了显示接口时序控制精度. 系统软件由驱动层、管理层和应用层组成,使得硬件管理与算法程序设计彼此分离,并能协同工作. 系统中的图像缓冲区采用了
三帧的配置方案,使得该平台最终具有对PAL/ N TSC 两种制式的全分辨率彩色复合视频信号进行实时采集、显示和处理的能力.-Based on high-speed digital signal processor (DSP) and large-scale field programmable gate array (FPGA), successfully developed a smaller, low-power real-time video capture, processing and display platform. One of the DSP is responsible for image processing, all its external digital logic functions are integrated in a FPGA, including high-speed video streaming FIFO, synchronous sequential generate and control, conversion and interface logic for video encoder/decoder to set up the control of nuclear and other I2 C. through increased FIFO bit width, increase the transmission bandwidth, reducing the time occupied by EMIF bus delay phase-locked loop using digital logic, Platform: |

Description: 数字基带信号的传输是数字通信系统的重要组成部分。在数字通信中,有些场合可不经过载波调制和解调过程,而对基带信号进行直接传输。采用AMI码的信号交替反转,有可能出现四连零现象,这不利于接收端的定时信号提取。而HDB3码因其无直流成份、低频成份少和连0个数最多不超过三个等特点,而对定时信号的恢复十分有利,并已成为CCITT协会推荐使用的基带传输码型之一。为此,本文利用VHDL语言对数据传输系统中的HDB3编码器进行了设计。-Digital baseband signal transmission is an important digital communication system components. In digital communications, some occasions may, after modulation and demodulation process, and on the base-band signals transmitted directly. AMI code using the turn signal inversion, there may be zero Silian phenomenon, which is not conducive to the receiving end of the timing signal extraction. HDB3 code and its non-DC components, and even less low-frequency components of 0 up to more than three the number of characteristics such as timing signals for the recovery of very favorable, and the Association has become the CCITT recommended base-band transmission-type, one code. In this paper, the use of VHDL language in the data transmission system HDB3 encoder has been designed. Platform: |
