The invention relates to the technical field of data transmission management, in particular to an FPGA-based multi-master-to-multi-slave access arbitration method, system and storage medium. The present invention standardizes and analyzes the read and write access data of each main port through the interface conversion module, and performs priority sorting and arbitration processing on the decoded read and write access data through the arbitration module, and expands independent write address channels, write data channels, Write response channel, read address channel, read data channel and read response channel, carry out orderly and stable transmission of read and write access data and corresponding response data between multi-master ports and multi-slave ports, so as to provide a set of efficient interactive design methods, Realize the optimization of the arbitration logic of multiple master ports accessing multiple slave ports, and solve the data conflict and stability problems in the process of multi-master multi-slave communication between multiple master ports on the chip and multiple slave function modules inside the FPGA.

The invention relates to the technical field of message sending and receiving, and discloses a periodic and non-periodic mixed communication method for low-speed serial bus. Send once per cycle, and aperiodic messages are sent when an emergency occurs; analyze whether the data message is sent at this time, whether there will be a conflict, and if so, the data message is temporarily stored in the cache Buffer; the server side When receiving the sending command, the flag bit Flag is set to 0, and after receiving the data message, set to 1; judge the sub-message type according to the Resp value, if it is the periodic message, then update the data, if it is the Aperiodic packets are written to RespBuffer. In the present invention, by setting the Buffer and the Flag, the periodic message and the non-periodic message are serially sent and received to prevent the conflict between the two, and quickly perform corresponding processing on the two.

The present invention proposes an information flow control method, including: acquiring data input into cloud services; judging whether the data is sensitive data; if the data is sensitive data, judging whether the data is sensitive according to the security label of the data Data conforming to preset sensitive data input rules; if the data is not data conforming to preset sensitive data input rules, prohibiting the data from being input into the cloud service. The above processing process realizes the identification of sensitive data that may bring conflicts of interest to cloud services, and effectively intercepts it, which can solve the problem of data conflicts in cloud composite services and avoid conflicts of interest in cloud services in cloud composite services.

This application relates to a data synchronization system, method, device and storage medium, belonging to the field of data synchronization technology, the system includes: a core domain and n-level service domains, there is at least one service domain including m platform domains, and the core domain is located at n-level The upper level of the service domain; the core domain, used to obtain the data update request sent by at least one lower-level service domain; execute the data update operation according to the data update request; obtain the data update path, and generate the data update message according to the data update path; guard through the core domain The process writes the data update message to the message queue subscribed by the first-level target service domain indicated by the data update path; the target platform domain in the i-level target service domain is used to obtain subscribed messages through the i-level daemon process Data update messages in the queue; perform data update operations according to the data update messages; can solve the problem of data conflicts; ensure data consistency after data updates.
