An embedded multimedia communication terminal based on DSP+FPGA

Abstract

The main content of this paper is the embedded multimedia terminal circuit design and the research and implementation of video image correlation algorithm based on Embedded Multimedia processor. The specific research contents include the design of embedded multimedia design, driving circuit of embedded multimedia DSP and the real-time performance of the algorithm based on the DSP program design. In this paper, the design of multimedia terminal circuit embedded multimedia DSP based on FPGA structure, including the design, multimedia DSP driver design and implementation of video algorithm. The embedded multimedia terminal with embedded multimedia DSP and FPGA structure, multimedia DSP as the main control CPU, responsible for functions such as audio and video collection, video display, signal processing and network communication; FPGA is used to realize the control logic and VGA and composite video switching circuit and video format conversion function. The embedded multimedia terminal has two video input; a video VGA and composite video optional output; stereo audio input and output; Ethernet communication function.
