Title:
DATA EXCHANGE METHOD, DEVICE, PROCESSOR, AND COMPUTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/120714
Kind Code:
A1
Abstract:
The present application provides a data exchange method, device, processor, and computer system, comprising: generating at least one source address read request, and sending at least one source address read request to a source storage unit, such that the source storage unit returns corresponding source data to a first buffer unit; generating at least one destination address read request, and sending at least one destination address read request to a destination storage unit, such that the destination storage unit returns corresponding destination data to a second buffer unit; determining that the source data can be transferred to the first buffer unit and that the destination data can be transmitted to the second buffer unit; according to the data received by a circular buffer unit, generating a corresponding address write request; using the address write request, sending the corresponding data to the destination address of the corresponding storage unit. In the present application, the circular buffer unit is used for achieving data exchange between the source storage unit and the destination storage unit; it is unnecessary to add a new kernel, and power consumption is reduced, thus saving costs.
