Many-core processor and methods of visiting space of many-core processor and main core of the many-core processor

Abstract

The invention relates to a many-core processor and methods of visiting space of the many-core processor and main core of the many-core processor, wherein the methods of visiting space of the many-core processor comprise that the main core builds page table buffering to subordinate cores, wherein the page table buffering is used for storing the page tables; the subordinate cores send service requirements to the main core; a one-to-one correspondence relationship is provided between the main core which loads the page tables in the page table buffering and the subordinate cores which send the service requirements to a process page table; the main core acquires a required page table entry from the process page table and starts page table mapping and then a physical address is generated; the main core visits physical space of the subordinate cores through the physical address. The many-core processor and methods of visiting space of the many-core processor and main core of the many-core processor effectively shields complexity of visiting hyperspace of heterogeneous many-core environment and achieves accurate and efficient visiting subordinate core spaces of the heterogeneous many-core environment.

Description

technical field [0001] The invention relates to the field of many-core processors, in particular to a many-core processor and its space access method and main core. Background technique [0002] With the development of semiconductor technology, traditional single-core processors have exposed many limitations. In order to reduce power consumption and heat dissipation while further improving processor performance, architecture designers have proposed multi-core processors. ) and many-core processors. Multi-core processors can be divided into two types: homogeneous multi-core processors and heterogeneous multi-core processors. The processor cores in the homogeneous multi-core processor are of the same type, and they are in an equal position in the multi-core processor; the heterogeneous multi-core processor contains different types of processor cores, and the different types of processor cores are in the multi-core processor. Play different roles. Many-core processors have m...

Problems solved by technology

[0005] The problem solved by the present invention is that in the prior art heterogeneous many-core processor environment, it is difficult for the master core to access the slave core space due to the multi-dimensionality of the physical space distribution of the slave cores.
