  • Patent number: 11709722
    Abstract: The present invention provides an extensible communication framework supporting multiple communication protocols, for connecting a software platform and a device. The extensible communication framework comprises a communication interface and a communication model, wherein the communication interface comprises a device interface, a channel interface and a protocol interface. The communication model calls the device interface, the channel interface and the protocol interface during communication. When the software platform is connected with the device, a class is created in the device interface, the class is inherited from the device interface; a channel protocol is newly created in the channel interface, the channel protocol is inherited from the channel interface; a sub-protocol interface is created in the protocol interface, the sub-protocol interface is inherited from the protocol interface.

  • Patent number: 11658680
    Abstract: A lossless compression method for a test vector has following steps: S01: converting the test vector into a data stream with A rows and B columns, the data stream is expressed in binary; S02: compressing the data stream a column by a column sequentially to form compressed words and uncompressed words corresponding to test datum of each of the B columns; a compression method for the test datum of each of the B columns comprises: setting a window with a width of 1 bit and a depth of M rows, and sliding the window down a row by a row from top of test datum of a column, and forming the compressed words and the uncompressed words corresponding to the test datum of each of the B columns; S03: converging the compressed datum of the test datum of each of the B columns to form a compressed data stream.

  • Patent number: 11620247
    Abstract: An adaptation method between PCIE and SPI realized based on FPGA, comprising following steps: S01: a PCIE equipment sends PCIE information to a mapping module through a PCIE module; S02: the mapping module extracts SPI information from the PCIE information and transmits the SPI information to a SPI equipment through an SPI module; all of the PCIE module, the mapping module and the SPI module are located on a FPGA chip; S03: the SPI equipment performs a read/write operation according to the SPI information, and feeds back SPI operation information subjected to the read/write operation to the mapping module; S04: the mapping module modifies PCIE information according to the SPI operation information to obtain PCIE feedback information; S05: the PCIE equipment reads the PCIE feedback information through the PCIE module.
