Conversion method of virtual and real addresses of many-core processor

Abstract

A conversion method of virtual and real addresses of a many-core processor comprises the following steps: step one, requesting an arbiter to arbitrate an instruction stream request and a data stream request from various processor cores; and step two, carrying out centralized substitution on an arbitrated instruction stream and an arbitrated data stream through an instruction stream substitution list and a data stream substitution list, wherein each processor core is fixedly distributed into a plurality of items in the instruction stream substitution list and the data stream substitution list, and after the instruction stream of the core is subjected to the unauthorized and bound check, and the substitution list item corresponding to the core is indexed by the virtual address, the physical address is substituted by a configurable substitution algorithm method, and the substitution list item comprises information on Cache consistency attribute configuration. The information on the Cache consistency attribute configuration comprises whether the arbitrated instruction stream and the arbitrated data stream can be cached to access, whether the cached strategy is subjected to direct writing or write-back, and whether the Cache access is subjected to write allocate.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, the present invention relates to a method for converting virtual and real addresses of many-core processors. Background technique [0002] With the improvement of single-core processor chip integration and main frequency, processor technology has encountered problems such as manufacturing cost, power consumption, heat dissipation, etc., prompting multi-core and multi-thread technology to become a new direction for the development of processor systems. A processor system integrating hundreds or even thousands of cores is generally called a many-core processor system. The increase in the number of cores in multi-core processor systems and many-core processor systems ensures continuous improvement in computing and data processing capabilities. [0003] A processor system integrating hundreds or even thousands of cores is generally called a many-core processor system...

AI Technical Summary

Problems solved by technology

[0005] However, the virtual-to-real address translation according to the prior art is either not suitable for many-core processors, or will bring huge overhead

In addition, the deficiencies of the existing technology also include TLB+ page table technology, segment table technology and segment page table technology of general-purpose processors, etc.

Moreover, shared Cache (high-speed cache) is generally an important factor for improving the performance of processor systems, but in many-core systems, due to the competition of many cores, access to shared Cache sometimes affects the performance of processor systems
