Abstract

The invention discloses a flow control method and a flower control device based on a counter. The device comprises a function unit, a counting unit, a control unit and a judging unit; the function unit comprises a plurality of function modules, the counting unit comprises a plurality of counting modules, and each function module is corresponding to one counting module; by means of judging values of the counting modules, effective control on flow process (such as coding and decoding of video) of each function module is realized, particularly in a case of being blocked ('full' condition ) or failed in fetching of preceding stage ('empty' condition), the function modules can temporally stop the flow process, conditions of data loss or generation of invalid data are guaranteed to be avoided, video coding can be more steady, and thus, the method and the device have wide market prospect in the field of computer chips.

Description

technical field [0001] The invention relates to the field of computer chips, in particular to a counter-based flow control method and device. Background technique [0002] With the rapid development of computer technology, communication technology, Internet technology and multimedia technology, multimedia applications have penetrated into every aspect of people's daily life and are gradually changing people's way of life. Video is the most common and informative medium in multimedia applications. At present, multimedia services have developed from audio-based to video-based. Whether it is traditional multimedia applications such as movies, TV, and video surveillance, or emerging multimedia applications such as web streaming video, videophone, and video conferencing, video is the key The most important part of it. [0003] In the process of video encoding or decoding, it often needs to be processed by multiple functional modules. Taking video coding as an example, the code...
