Processor, data transmission method thereof and computer readable storage medium

Abstract

The invention discloses a data transmission method of a processor. The processor comprises a first core and a second core, the data transmission method of the processor comprises the following steps of obtaining to-be-distributed data by the first core, and after the first core obtains the to-be-distributed data, storing the to-be-distributed data in an internal memory of the first core; and writing the to-be-allocated data into an external memory of the processor, and after the to-be-allocated data is written, obtaining the data in the external memory by the second core. The invention furtherdiscloses a processor and a computer readable storage medium, the first core transmits the to-be-allocated data to the second core through the external memory of the processor, the data do not need to be directly copied between the first core and the second core, the problem that the occupancy rate of the processor is too high is avoided, and therefore the utilization rate of the processor is increased.

Description

technical field [0001] The present invention relates to the technical field of processors, in particular to a processor, a data transfer method thereof, and a computer-readable storage medium. Background technique [0002] When performing data processing, multiple cores of a multi-core processor generally work at the same time. The first core assigns part of the data processing tasks to other cores. After the other cores complete the processing, the data is sent back to the first core to improve data processing. s efficiency. [0003] The communication between multiple cores mainly adopts the way of Multicore Communications Application Programming Interface (MCAPI, Multicore Communications Application Programming Interface), which makes the communication process more complicated, and the data needs to be directly copied between multiple cores, resulting in higher resource consumption of the multi-core processor. High, low resource utilization. [0004] The above content is...
