2 results about "Synchronous Serial Interface" patented technology

The disclosure provides a multi-channel synchronous serial interface parallel communication system and a data transmission method, which can be applied to the technical field of data communication. The system comprises a substrate; a master chip located in the middle part of the substrate, used for data transceiving and protocol analysis; at least three groups of synchronous serial interface channels located on the second side of the substrate, each group of the synchronous serial interface channels comprising two differential transceivers; a host computer interaction unit located on the first side of the substrate and a power supply circuit comprising a two-stage voltage reduction structure, the host computer interaction unit integrating multiple serial interfaces to adapt to different host computers. The method comprises: receiving and verifying a host computer data request frame, storing valid data into an independent cache area of a corresponding channel and returning a response; synchronously listening to clock signals of each channel, and driving corresponding data differential transceivers to output cached data under the falling edge of each clock. The disclosure realizes hardware-level parallel, synchronization and low-delay transmission of multi-channel data.

This invention provides a method and system for receiving SSI protocol data based on SPI, belonging to the field of data transmission. The method includes: configuring a microcontroller to enable its serial peripheral interface to perform data transmission using direct memory access; determining the target number of bytes based on the data acknowledgment response time length of the synchronous serial interface, the total number of effective bytes, and the baud rate of the serial peripheral interface, and determining a synchronization clock signal and data to be transmitted based on the target number of bytes; sending the synchronization clock signal and data to be transmitted to the synchronous serial interface through the serial peripheral interface, while simultaneously receiving data to be decoded sent by the synchronous serial interface, and storing the data to be decoded in a receive buffer; decoding the data to be decoded in the receive buffer when the number of bytes of data to be decoded in the receive buffer equals the target number of bytes. This invention allows the microcontroller to directly receive SSI protocol data, reducing hardware complexity and cost.
