Description
Technical field
The present invention relates to the coding and decoding video field, adaptive parallel method of coding and decoding video dynamic multiple resolution ratio and system under particularly a kind of many nuclear environments.
Background technology
Video decode application need under the complex environment is handled mass data simultaneously, these data have multiple code stream form, multiple resolution, adopt traditional DSP, FPGA, ASIC hardware cell, risc processor etc. all to be difficult to satisfy performance and the requirement of multi-format decoding function.
Adopt the many-core processor technology of 64 cores, utilize the abundant computational resource of many nuclears, carry out video decode by software and handle, can satisfy and separate the various video form simultaneously, the application demand of multiple code stream resolution.
Summary of the invention
The purpose of this invention is to provide a kind of parallel method and system that controls the multiple nucleus system computational resource allocation, code stream form and resolution according to current decoding, the dynamic computational resource allocation of adjusting, the feasible computational resource that makes full use of system satisfies various different-formats and the resolution demand to the decoding computational resource.
The parallel decoding method of dynamic self-adapting comprises the steps: under a kind of many nuclear environments
A, system initialization are according to system task attribute configuration table default configuration, distributes calculation resources and IO resource;
B, data input module are deposited into raw data in the shared data field of all modules after receiving packet, and each decoder module obtains decoding task to sharing data area;
C, decoder module inquiry system task attribute allocation list if there is one road video to need multinuclear to assist parallel decoding, are then revised system task attribute configuration table, and register module computational resource participates in this road decoding;
D, request if nothing assistance is decoded, then whether inquiry has new task, as if having, obtains new task;
E, decoder module are resolved new task form and resolution, and judging whether needs to assist decoding, if need to assist decoding, then the decoding request is assisted in issue, revises system task attribute configuration table; After new core adds, distribute decoding task to give new core, parallel decoding is finished this road video decode task, after task is finished, gives back the resource of adding, recovers on-the-spot.
A kind of optimal technical scheme of the present invention is: described system task attribute configuration table is done dynamic assignment according to operating code stream form of current system and resolution situation to computational resource.
The parallel decoding system of dynamic self-adapting under a kind of many nuclear environments is characterized in that: comprise system initialization module, load module, decoder module, output module and statistics and state monitoring module.
A kind of optimal technical scheme of the present invention is: each computing unit of described decoder module is analyzed current system task attribute configuration table, decides the decoding of getting new calculation task or certain promoter's of participation big resolution video from task list according to system task attribute configuration table.
Another optimal technical scheme of the present invention is: described statistics and state monitoring module, and generation system task attribute allocation list, this allocation list is dynamically adjusted resources allocation according to operating code stream form of system and resolution situation.
An also optimal technical scheme of the present invention is: described system initialization module is used for distributes calculation resources and IO resource, creates each calculation task and IO task; Described load module receives the data block that needs decoding, generates decoding task, puts into task list; Data behind the output module output decoder.
The operation task that the present invention can be dynamically adjusts each core according to the code stream form in the system and resolution distribution, thus for different code streams form and different resolution can both obtain the computational resource of decoding fully, guarantee the quality and the performance of system.

Specific embodiments
Below in conjunction with the drawings and specific embodiments method of the present utility model is described.
During system initialization, according to the default configuration of system task attribute configuration table, distributes calculation resources and IO resource.
Data input module is deposited into raw data in the shared data field of all modules after receiving packet, and each decoder module obtains decoding task to sharing data area.
Decoder module was inquired about current system task attribute configuration table before obtaining new task, seeing if there is certain road video needs multinuclear to assist parallel decoding, if have, revise system task attribute configuration epiphase and close project, the computational resource of register module participates in the parallel decoding on this road.
If can obtain new task, get new task, resolve the form and the resolution of new task, whether decision needs to initiate to assist the decoding request.Other cores are assisted decoding if desired, and can issue new decoding and assist request, revise system task attribute configuration epiphase so and close project, and request is assisted in the issue decoding.Behind other cores registration computational resources, the distribution decoding task is given the core that adds, and parallel decoding is finished the decoding task of this road video.After task is finished, give back the computational resource of adding, recover on-the-spot.
