Abstract

The invention relates to the technical field of communication, and discloses a data scheduling method and device. The method comprises the following steps: receiving a video and/or image data stream;storing the received data stream according to the state of each cache region in a first double cache based on a write command; outputting the stored data stream according to the state of each cache region in the first double cache based on a reading command; carrying out formatting preprocessing on the output data flow; storing the formatted and preprocessed data flow according to the state of each cache region in a second double cache based on a write command; outputting the stored formatted preprocessed data stream according to the state of each cache region in the second double cache basedon a reading command; and carrying out data distribution on the output formatted and preprocessed data flow. Therefore, multi-data-stream access can be processed, and real-time scheduling of large-throughput data is realize.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a data scheduling method and device. Background technique [0002] In the field of data link ground application system design, the software service system is generally designed on the basis of multi-task computing. The multi-task mode satisfies the characteristics of multiple business types and frequent task scheduling in the data link ground application system to a certain extent, but the multi-task software service system that relies on the operating system for conventional construction has not been specially optimized for multi-core computing. The utilization rate of processing cores of multi-core computers is generally low, so their business processing capabilities and task scheduling capabilities are restricted, which cannot meet the needs of complex data link ground application systems. [0003] On the other hand, with the development of data link technology...
