Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0047] The present invention adopts the mode of Intel master control chip and Netra slave chip to realize the video code stream processing equipment, reads video code stream by Intel master control chip, uses Netra to process the video code stream read from chip again; Like this, Intel master The control chip runs under the windows system, and can normally run the SDK to read the video code stream when needed; and fully utilizes the strong processing capability of the Netra chip to process the read video code stream. Therefore, not only the code stream processing capability is improved, but also the problem of limited video code stream processing is solved.

[0048] see figure 1 , which is a schematic structural diagram of a device for video stream ...

Abstract

The invention discloses a device and a method for video stream processing, wherein the device includes an Intel main control chip, a PCI-E bridge chip and at least one Netra slave chip; the Intel main control chip reads video from an external device Code stream, configure the mapping space from the chip, determine the address of the mapping space, and send the video code stream to the Netra slave chip shared memory corresponding to the address of the mapping space through the PCI‑E bridge chip; the PCI‑E bridge chip performs Intel master control Information interaction between the chip and the Netra slave chip; the Netra slave chip reads the video code stream from the shared memory, performs code stream video processing, and sends out the processed code stream. The scheme of the invention can not only improve the processing capacity of the code stream, but also solve the problem of limited processing of the video code stream.

Description

technical field [0001] The present invention relates to information processing technology, in particular to equipment and method for processing video code stream. Background technique [0002] In the field of video data processing, people have higher and higher performance requirements for devices to process video streams, and the device performance of a single chip can no longer meet market demand. Therefore, multi-core chip solutions have developed rapidly in recent years, and various solutions have emerged in an endless stream. [0003] The processing of the video code stream by the device specifically includes: the chip reads the video code stream from the external device, performs video processing on the code stream, and sends out the processed code stream. [0004] The current multi-core chip solution is basically a combination of multiple Intel chips or a combination of multiple Netra chips, which will be described separately below. [0005] Option 1, the device cons...
