Problems solved by technology

However, this will also increase the burden of data transmission and reduce the efficiency of data transmission; in addition, the length of identification data at the transmission end and the receiving end is usually designed as a fixed length in the same system, so for higher important Permanent data or links with long circuit transmission paths lack the flexibility to adjust the length and content of identification data 12

Embodiment Construction

[0033] Please refer to FIG. 3 , which is a schematic diagram of a data synchronization system 30 of the present invention. The present invention relates to a data synchronization system 30 for forming a data packet when transmitting a transmission data string from the sending end to the receiving end as shown in FIG. 1 . The sending end and the receiving end may be two circuit boards respectively. The data packet includes identification data and content data as shown in FIG. 2 , the content data has a predetermined data length, and the identification data includes guard data and pattern data. The content data may be program code, numerical data, image data, or voice data.

[0034] Returning to Fig. 3, the data synchronization system 30 includes a pattern number registration module 32, an identification data arrangement module 34, a one-bit image module 36, a calculation module 38, an identification data selection module 40, and a data combination module 42 .

Abstract

A data synchro system and method is used to form data packet with identification data comprised protection data and image data, and content data. Choose the bit number of image data firstly; according to protection data and bit number aforementioned, generate multiple groups identification data; then, take bit mapping for multiple groups and converse to multiple groups compute data; take semi-auto correlation operation to compute data, corresponding to compare parameters; later, select the identification data with minimum compare parameter; finally, combine selected identification data and content to data packet.

Description

technical field [0001] The invention relates to a data synchronization system and method, in particular to a data synchronization system and method utilized between circuit boards. Background technique [0002] Please refer to FIG. 1 , which is a schematic diagram of data transmission in a known technology. One circuit board is regarded as the sending end 2 , and the other circuit board is regarded as the receiving end 4 , which are connected by a signal line 6 , and a transmission data string is transmitted from the sending end 2 to the receiving end 4 . In order to enable the sending end 2 and the receiving end 4 to have the same understanding of the data, even if the data at both ends 2 and 4 are synchronized, the transmitted data will be transmitted in the form of a data packet (data packet), so that The receiver 4 can distinguish the content of the received data. [0003] Please refer to FIG. 2 . FIG. 2 is a schematic diagram of the transmission data string 8 in the k...
