Embodiment Construction

[0052] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and are not used to limit the application.

[0053] In one embodiment, such as Figure 1 As shown, a data access circuit 100 is proposed, which includes an interconnected read-write control circuit 110, a read-write circuit 120 and a memory 130. The read-write control circuit 110 is used to generate data read-write parameters and generate 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 a specific read-write operation. Specifically, the data read-write parameters generated by the read-write control circuit 110 include: read-write start address, ...

Abstract

The present application relates to a data access method, a data processing method, a data access circuit and a computing device. By generating read and write parameters, a data block in the data to be accessed is purposely obtained. It is not necessary to access the data blocks in the stored data according to the storage order, and in the data access method in the above embodiment, by introducing the access parameters such as the step size and the number of single-time read and write blocks, access to the storage in a two-dimensional manner is realized. This provides great convenience for processing data with two-dimensional similarities such as natural images and feature maps.

Description

technical field [0001] The 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 technology [0002] Data is recorded in some format on the internal or external storage medium of the computer. Data access refers to the storage and acquisition of data in the computer. The access objects include the temporary files generated by the data stream in the processing process or the information to be found in the processing process. [0003] In traditional technology, the stored data needs to be accessed according to the storage order. There are many restrictions on reading and writing operations, and the way to obtain data is not flexible. summary of the invention [0004] Based on this, it is necessary to provide a data access method, data processing method, data access circuit and operation device that can flexibly obtain target data for the above technical p...
