Embodiment Construction

[0025] Technical scheme of the present invention is as follows:

[0026] According to the first object of the present invention, a data storage structure for a many-core processing system is proposed, which is used to realize an array of M×N (M, N are positive integers) many-core computing units (the distribution of the computing units is represented by M rows The form distribution of N columns) and the data interaction between the system main control core and the external storage unit, such as figure 2 As shown, it includes a global shared memory 100 , an external data transmission controller 200 , and an internal data transmission controller 300 .

[0027] The global shared memory has the function of storing the data read and written by the main control core through the external data transmission controller and storing the data read and written by the many-core computing unit array through the internal data transmission controller, and serves as the A memory that can be re...

Abstract

The invention relates to the technical field of computers, aims to solve the problem that according to a multiple core processor, the data storage delay is large, the transmitting efficiency is low, and the multiple core calculating unit array parallel calculating efficiency cannot be improved continuously and provides a data storage structure for the multiple core processing system and a data access method for the data storage structure of the multiple core processor. The accessing and storing costs of the multiple core processing system can be reduced, and the accessing and storing efficiency is improved, and the parallel calculating efficiency of the multiple core processor can be improved. Thus, according to the technical scheme, the data storage structure for the multiple core processing system comprises a global shared memory, a foreign data transmission controller and an internal data transmission controller. The data storage structure and the data access method for the multiple core processing system are mainly applied to computer design and manufacture.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data storage structure and a data access method for a many-core processing system. technical background [0002] The many-core processor is a new parallel processor architecture. Compared with the traditional general-purpose single-core processor, the processing capacity is significantly improved. Compared with the ASIC chip, it can ensure high efficiency without losing flexibility. scientific research and practical value. Both multimedia information processing and modern communication information processing have the characteristics of large-scale parallelism such as data-intensive and calculation-intensive, and many-core processors have significant advantages in processing these information. [0003] Many-core processor is a broad concept, and there are many implementation forms, and reconfigurable processor is one of them. An existing typical many-core processing system s...
