Abstract: Aiming at the H3MP16 multi-core processor, this paper designs a streaming media presenting system to test the performances of it. It introduces the hardware structure of the H3MP16 multi-core processor, explains the frame and the function of the test system, and then discusses the design solutions. It proposes a program to send and capture packets based on socket communication, and performs the online synchronous transfer and display of FFMPEG, tests the packet loss rate and playing effects. It succeeds to provide an effective test platform for multi-core processor.
