[0003] However, the inventor found in the process of implementing the embodiment of the present invention that since several registers of each chip are connected in series to form a chain, the chip array connects several chips in series to form a very long chain, resulting in a long access time Very long, especially if you want to access a specific register, you need to "traverse" the entire chain, which is very inefficient and time-consuming

The invention relates to the technical field of data communication, and discloses a data transmission system and method. The system comprises an SPI (Serial Peripheral Interface), an auxiliary control signal interface, a multi-stage chip, a command chain and a data chain, and the data chain comprises a common link, a local link, a custom link and a specified address link. According to the data transmission system and method, a data transmission mode is determined according to a command chain, a common link, a local link, a custom link and a specified address link, and data is transmitted through the determined transmission mode according to a signal indicated by an auxiliary control signal interface. According to the data transmission system and method, corresponding data transmission modes can be selected according to different application scenes to access the multi-stage chip, so that the access of the multi-stage chip is more flexible, and the access speed and efficiency are greatly improved.
Description
technical field [0001] The present invention relates to the technical field of data communication, in particular to a data transmission system and method. Background technique [0002] In multi-chip cascading, especially in large-scale arrays of radio frequency chips, how to realize communication with each chip is more difficult to deal with. At present, related technologies adopt a serial peripheral interface (Serial Peripheral Interface, SPI) daisy chain structure cascading, so as to realize communication with cascading chips. The related technology connects all the registers of all the chips that are expected to be accessed in series, so that only one master interface is needed to access the slave interface of each chip. [0003] However, in the process of realizing the embodiment of the present invention, the inventors found that since several registers of each chip are connected in series to form a chain, the chip array connects several chips in series to form a very l...
