Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0053] In one of the examples, as figure 1 As shown, a data access circuit 100 is proposed, which includes a read-write control circuit 110 , a read-write circuit 120 and a memory 130 connected to each other. Wherein, the read-write control circuit 110 is used for generating data read-write parameters, and generating read-write control instructions according to the data read-write parameters. The read / write control instruction is used to control the read / write circuit 120 to complete specific read / write operations. Specifically, the data read and write parameters generat...

Abstract

The invention relates to a data access method, a data processing method, a data access circuit and an arithmetic device, and aims to obtain data blocks in to-be-accessed data by generating read-writeparameters. The data blocks in the stored data do not need to be accessed according to the storage sequence; in addition, according to the data access method in the embodiment, by introducing the access parameters such as the step length and the single read-write block number, the stored data can be accessed according to a two-dimensional mode, and great convenience is provided for processing natural images, feature maps and other data with two-dimensional similarity.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a data access method, a data processing method, a data access circuit and a computing device. Background technique [0002] Data is recorded in a certain format on a computer internal or external storage medium. Data access refers to the storage and acquisition of data in the computer. The objects of access include temporary files generated during the processing of data streams or information that needs to be searched during processing. [0003] In the traditional technology, the stored data needs to be accessed according to the storage order, the read and write operations are limited, and the way to obtain the data is not flexible. Contents of the invention [0004] Based on this, it is necessary to provide a data access method, a data processing method, a data access circuit, and an arithmetic device capable of flexibly acquiring target data for the above tech...
