  • Method and system for facilitating communication between a host and downstream devices in a data storage system
    Patent number: 8639864
    Abstract: A diplex FPGA is utilized to fan out a single high speed host universal asynchronous receiver transmitter (“UART”) channel into a number of diplex UART channels. The diplex FPGA includes a microprocessor, memory, a host UART and a number of diplex UARTs. In operation, the microprocessor polls each of the UARTs in a “round robin” manner and accepts packets from the host UART for transmission downstream and from the diplex UARTs for transmission upstream.
