Description

technical field [0001] The present invention relates to a streaming media storage device, that is, a chip or FPGA, in particular to a multi-flash parallel storage device with a network direct-play function, that is, a chip or FPGA. Background technique [0002] With the continuous advancement of my country's broadband Internet construction and the continuous advancement of the network integration of three networks, more and more users have begun to use IP-based broadband services, and the broadband era of converged communications has arrived. This makes many IP-based multimedia services possible, such as broadband cinema, Internet TV, video conferencing, distance education, telemedicine, network video surveillance, online live broadcast system, etc. [0003] As the core technology of broadband services, streaming media technology has been greatly developed in recent years. Streaming media refers to the media form of transmitting audio, video and multimedia files in the netwo...

Problems solved by technology

[0005] At present, the main streaming media server adopts the traditional X86 architecture. With the rapid increase of network streaming media traffic, the traditional architecture encounters the following performance bottlenecks: the storage system is still based on the mechanical hard disk. Its structural weakness, the read and write speed is limited by the physical rotation speed of the disc and the read and write speed of the magnetic head, and there is also the problem of random read difficulty, which leads to the slow progress of its continuous read and write speed, which greatly lags behind the starting capacity Growth rate; in the X86 architecture, the network interface and the storage system are independent subsystems, and there is no direct playback channel for the two, so that a large amount of streaming media playback still passes through the main memory of the system, causing streaming media playback to greatly consume system resources and affect host performance.
