Problems solved by technology

[0005] However, different extension cores in the above method include different extension instruction sets, which makes the overall structure more complicated, and its all-round core / basic core and all extension cores are all connected to the same on-chip bus for communication, and the number of extension cores cannot be too large. Many, otherwise it will cause more conflicts in the communication process of the on-chip bus, so the calculation density of the multi-core processor with this structure is low

Embodiment Construction

[0050] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0051] In the heterogeneous multi-core processors of the prior art, all processor cores are generally connected to the same bus, which increases the conflicts in the communication process and lowers the communication efficiency. In order to avoid too many conflicts, the number of slave cores is often small , affecting the improvement of the computing density of the entire heterogeneous multi-core processor.

[0052] The technical solution of the present invention adopts a two-level interconnection structure, wherein the first interconnection structure is used for communication between the master core and the slave core array, and the slave core interconnection structure is used for communication between any t...

Abstract

The invention relates to a multi-core processor and a multi-core processor set. The multi-core processor comprises at least one master core, at least one slave array, a first interconnecting structure and a slave core interconnecting structure, wherein the slave core array comprises a plurality of slave cores which are heterogeneous with the master core; the first interconnecting structure and the slave core interconnecting structure are used for communication between the master core and the slave core array; the slave core interconnecting structure is used for communication between any two slave cores in the slave core array; and as an optimized technical scheme, the master core is a universal processor core, the slave cores are processor cores microstructures and instruction sets of which are simplified and optimized, and the multi-core processor is integrated on the same chip. According to the multi-core processor and the multi-core processor set disclosed by the invention, communication efficiency among the processor cores is improved, calculation density of the whole multi-core processor is increased and balance between universal control function and high calculation density is realized.

Description

technical field [0001] The invention relates to the field of processors, in particular to a multi-core processor and a multi-core processor group. Background technique [0002] With the development of information technology, the demand for processing and computing power of computer processors is getting higher and higher, and traditional single-core processors can no longer meet the needs. Therefore, multi-core processors and many-core processors (many-core processors) -core processor) has gradually been widely used. A multi-core processor refers to the integration of two or more processor cores in one processor. By dividing tasks among the cores, the parallel operation of multiple processor cores is realized, thereby improving the computing power of the entire processor. processing power. [0003] Multi-core processors can be divided into homogeneous multi-core processors (homogeneous multi-core processors) and heterogeneous multi-core processors (heterogeneous multi-core...
