基于DSP与FPGA的音视频无线传输系统设计

Audio and Video Wireless Transmission System Design Based on DSP and FPGA

为满足野外突发事件下的音视频实时传输的需要,以TMS320C6201 DSP、EP1C6Q240C8 FPGA为核心处理器和协处理器,以基于CCS2.20及DSP/BIOS集成开发环境设计C和ASM语言混合驱动程序,开发出了一款嵌入式实时音视频无线传输系统。该系统最大传输速率可达150Mbps、通信距离可达300米,并具有体积小、重量轻、便于携带等特点。

In this paper,an embedded system for real-time wireless transmission of audio and video is designed to serve the purpose of realtime transmission of audio and video on unexpected occasions,with MS320C6201 DSP as the core processor and EP1C6Q240C8 FPGA as the coprocessor.The system,written by C language and assemble language in CCS2.20 and DSP /BIOS integrated development environment,has a maximum speed of 150Mb/s and communication distance is up to 300 metres.This paper mainly focuses on the design guidelines of the system as well as its hardware and software design and etc.
