Title:
METHOD FOR TRANSMITTING DATA AMONG MULTIPLE CPUS
Document Type and Number:
WIPO Patent Application WO/2024/011708
Kind Code:
A1
Abstract:
A method for transmitting data among multiple CPUs. The method comprises: multiple CPUs share one RAM used for transmitting data; a data bus of the RAM is connected to a control module, and then the control module is connected to a data bus of each CPU; the control module may be a traffic light type control module or an intelligent control module; during a period of time, the data bus of the RAM is exclusively occupied and used by only one CPU; and the CPU exclusively occupying the data bus of the RAM performs data read/write operation on the RAM within the exclusive occupation time. The method has the advantages that: 1) viruses will not be able to steal, detect and tamper with transmitted data by using security vulnerabilities of an operating system and an application system; and (2) data transmission between two CPUs will not depend on a communication protocol any more. Communication protocol security vulnerabilities are thus fully eliminated.
