Title:
DIRECT MEMORY ACCESS ARCHITECTURE, SYSTEM AND METHOD, AND ELECTRONIC DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/185035
Kind Code:
A1
Abstract:
Disclosed in the present application is a direct memory access architecture. The direct memory access architecture comprises a direct memory access control component, a read data moving component, a write data moving component and a data storage component. The direct memory access control component comprises a control register, a read descriptor storage component, a write descriptor storage component, a read command transmission component and a write command transmission component, wherein the control register is configured to be set by a host to obtain descriptor address information, the read descriptor storage component is configured to store a read descriptor, which is obtained by using the control register, the write descriptor storage component is configured to store a write descriptor, which is obtained by using the control register, the read command transmission component is configured to send to the read data moving component a read command, which is obtained on the basis of the read descriptor or the descriptor address information, and the write command transmission component is configured to send to the write data moving component a write command, which is obtained on the basis of the read descriptor. The read data moving component is configured to execute the read command, and the write data moving component is configured to execute the write command. The architecture can implement parallel processing of reading and writing and is highly efficient.
