However, each core is passive and executes operation energy according to an operation program instruction, and the control capability of the core is weak and the flexibility is poor.
In order to solve the above problems, in the embodiments of the present disclosure, a core cluster is dynamically configured according to a computing task, where the core cluster includes a plurality of cores, and a many-core system may have a plurality of core clusters, where each core cluster executes a corresponding computing task, so as to enhance control over each core and improve flexibility of executing the computing task. However, the core clusters are independent of each other, so that data interaction cannot be performed, and the flexibility of the cores in the many-core system in executing the computing task is still limited.
In view of this, in a first aspect, referring to fig. 1, an embodiment of the present disclosure provides a data transmission method, applied to a core in a many-core system, the data transmission method including:

In the embodiment of the present disclosure, the core cluster to which the current core belongs is referred to as a current core cluster, the core that sends the first request signaling is referred to as a request core, and the core cluster to which the request core belongs is referred to as a request core cluster. The request core may be a master core in the request core cluster or a slave core in the request core cluster. The embodiments of the present disclosure are not particularly limited thereto.

The private data is data which is only read by the current core and/or the core in the core cluster to which the current core belongs; the public data is data with read authority of any core in the many-core system; the friend metadata refers to data that only the friend core of the current core has read authority.
In the embodiment of the disclosure, the data pointed by the first request instruction may be private data, friend metadata, or public data; in addition, the data pointed by the request instruction can be other information required for completing the data interaction between the core clusters. The embodiments of the present disclosure are not particularly limited thereto.
As an alternative embodiment, in step S120, the current core transmits data to the requesting core through a Network On Chip (NOC).
According to the data transmission method provided by the embodiment of the disclosure, the core in the many-core system can transmit the data pointed by the request signaling to the request core according to the request signaling sent by the request core, wherein the request core and the current core belong to different core clusters, so that the data interaction among the different core clusters is realized, the flexibility of the core in processing the calculation task is improved, and the operation capability of the many-core system is improved.

In the embodiment of the present disclosure, the core cluster to which the current core belongs is referred to as a current core cluster, the core that sends the first request signaling is referred to as a request core, and the core cluster to which the request core belongs is referred to as a request core cluster. The request core may be a master core in the request core cluster or a slave core in the request core cluster. The embodiments of the present disclosure are not particularly limited thereto.

In the embodiment of the disclosure, the data pointed by the first request instruction may be private data, friend metadata, or public data; in addition, the data pointed by the request instruction can be other information required for completing the data interaction between the core clusters. The embodiments of the present disclosure are not particularly limited thereto.
As an alternative embodiment, in step S220, the current core transmits data to the requesting core through a Network On Chip (NOC).
According to the data transmission method provided by the embodiment of the disclosure, the core in the many-core system can transmit the data pointed by the request signaling to the request core according to the request signaling sent by the request core, wherein the request core and the current core belong to different core clusters, so that the data interaction among the different core clusters is realized, the flexibility of the core in processing the calculation task is improved, and the operation capability of the many-core system is improved.

In the disclosed embodiments, the requesting core may also access private data in the current core. As an alternative embodiment, when the requesting core requests access to private data in the current core, unified scheduling and control is performed by the master core in the current core cluster. Specifically, the main core in the current core cluster generates a token according to the request signaling of the request core, and the current core only allows the request core with the valid token to access the private data, so that the data security can be ensured.
Accordingly, in some embodiments, referring to fig. 6, before step S210, the data transmission method further includes:

The embodiment of the present disclosure is not particularly limited as to how to perform step S232 to verify the validity of the token. For example, the identity of the request core may be verified according to the identity of the request core carried in the token; verifying the authenticity of the token according to the token code carried in the second token; and verifying whether the request core has the access right of the data pointed by the request signaling or not according to the read right information and the data address information carried in the second token.

As an optional implementation manner, step S240 may also be performed when the request core requests non-friendly metadata, and when the request core is a friendly core, the request core is allowed to directly read corresponding data, so that data interaction efficiency can be improved.
In the embodiment of the disclosure, the request core can perform data interaction with the slave core in the current core cluster, and the slave core in the current core cluster obtains the friend metadata.
