Access control method and device, access method, storage method and access system

Abstract

The invention discloses a method and device for access control, an access method, a storage method and an access system, wherein the method for the access control comprises the steps that when respective data access demands appear in M access units of a first access main body, storage addresses in storage equipment are set according to the data access demands, N storage units are divided in the storage equipment, and a second access main body stores N pieces of target data into the N storage units of the storage equipment respectively according to the data access demands; respective data access channels of the M access units in the first access main body are established according to the data access demands, each data access channel communicates with the corresponding access unit and at least one storage unit corresponding to the access unit, and each access unit access the data in the corresponding storage unit via the respective data access channel simultaneously; and M and N are positive integers, and N is larger than or equal to M.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to an access control method and device, an access method, a storage method and an access system. Background technique [0002] Existing memories such as tightly coupled memory TCM need to be accessed multiple times by logic circuit ASIC or central processing unit CPU during its application process. For example, when running fingerprint identification algorithm, ASIC needs to access the memory multiple times. [0003] However, due to the bandwidth limitation of accessing the data port in the memory, when large data needs to be read, it is usually necessary to read the data in the memory by accessing the data port multiple times, so that the rate of reading large data is relatively slow. Contents of the invention [0004] The object of the present invention is to provide an access control method and device, an access method, a storage method and an access system, which are used...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an access control method and device, an access method, a storage method and an access system to solve the problem in the prior art when reading large data due to the bandwidth limitation of the data port of the accessed memory. The reading task of large data needs to be accessed multiple times to the memory, which makes the reading rate of large data slow.
