Problems solved by technology
[0005] However, this method of data interaction between processor cores requires multiple accesses to the cache, and data interaction between different processor cores may require more than 3 access operations to complete the data interaction, that is, the processor core requesting data needs to access Local first-level cache, second-level cache, until access to the second-level cache of other processor cores
This method of data communication between processor cores still cannot effectively improve the data processing capability of the processor.

Embodiment Construction
[0036] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0037] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways than those described here, so the present invention is not limited by the specific embodiments disclosed below.
[0038] As mentioned in the background section, in the prior art, data interaction between processor cores of a multi-core processor needs to access caches between processor cores, and the slow reading speed of the cache reduces the data processing capability of the multi-core processor.
[0039] In view of the above problems, the inventors of the present invention provide a communication method and a communication device for direct data in...

The invention relates to a communication method and device of processor cores based on an array structure. The communication method of the processor core based on the array structure comprises the following steps: a transmitting-end processor core acquires a data transmitting instruction and analyzes the data transmitting instruction; the transmitting-end processor core acquires data from a universal register file of the transmitting-end processor core on the basis of an analysis result of the data transmitting instruction, and stores the data into a transmitting buffer unit of the transmitting-end processor core; the transmitting-end processor core transmits data of the transmitting buffer unit of the transmitting-end processor core to a receiving buffer unit of a target processor core indicated by the data transmitting instruction; the target processor core acquires a data receiving instruction and analyzes the data receiving instruction; and the target processor core acquires data from the receiving buffer unit of the target processor core on the basis of an analysis result of the data receiving instruction and stores the data to a universal register file of the target processor core.
Description
technical field [0001] The present invention relates to a microprocessor architecture, and more specifically, the present invention relates to a communication method and a communication device based on a processor core of an array structure. Background technique [0002] A multi-core processor refers to the integration of multiple processor cores and related functional components into one processor chip, thereby forming a processor structure including multiple processor cores. Compared with previous single-core processors, due to the integration of multiple processor cores, the data processing capability of the multi-core processor is greatly improved. [0003] While the data processing capability of the multi-core processor is greatly improved, the access speed of the processor's external memory is relatively slow, especially the access speed of the system memory is far from meeting the processing speed of the processor. Since the multi-core processor usually has multiple ...
