Title:
COMMUNICATION METHOD AND APPARATUS FOR DOUBLE CPUS IN POS MACHINE, SYSTEM AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/041304
Kind Code:
A1
Abstract:
The present application belongs to the technical field of POS machines, and particularly relates to a communication method and apparatus for double CPUs in a POS machine, a system and a medium. The communication method comprises: a security CPU receives a target service calling request initiated by a general CPU; the security CPU controls, according to the target service calling request, a client of a remote file system to initiate to a server of the remote file system a target service execution request, so that after receiving the target service execution request, the server of the remote file system can execute a target service on a storage module of the general CPU side, and send the execution result to the client of the remote file system; and the security CPU returns back to the general CPU the execution result received by the client of the remote file system. The present application allows a security CPU to share a storage module of a general CPU side, thus reducing the system cost of the double CPUs; using a communication mechanism of a remote file system improves data interaction efficiency.
