摘要

本文设计了一款专门应用于视频数据分发的分发芯片，由接收模块、存储截取模块、输出模块和时钟模块4部分组成。接收模块接收来自串行总线的串行数据，因为LED显示屏的LED灯珠由24位的RGB数据驱动，所以先将其转化为24位的RGB数据。存储截取模块将1~

个RGB数据循环存储到RAM中，并对其进行开关检测。当与开关一致时，读取这一循环的RAM中的

个数据并将其发送到输出模块，不一致时循环次数加一。输出模块将RGB转化为串行数据后发送到LED显示屏。最终设计报告表明，分发芯片的功耗为3.662e-05 mW，面积为3.702

Abstract

A distribution chip specially used for video data distribution is designed in this paper. The distribution chip is composed of four parts： receiving module， memory intercepting module， output module and clock module. The receiving module receives the serial data from the serial bus. Because the LED beads of the LED display screen are driven by 24 bit RGB data， the serial data are converted into 24 bit RGB data. The storage interception module stores 1~

RGB data cycles in RAM， and detects their switches. When they are consistent with the switches， it reads

data in the RAM of this cycle， and sends them to the output module. When they are inconsistent， the number of cycles increases by one. The output module converts RGB into serial data and sends it to the LED display screen. The final design report shows that the power consumption of the distribution chip is 3.662e-05 mW and the area is 3.702
