Patent ID: 11474969

Abstract:
A method for providing a high-speed data communication between a host and field-programmable gate array (“FPGA”) is disclosed. The method, in one embodiment, is capable of identifying a data rate on a bus containing a P-channel and an N-channel operable to transmit signals in accordance with a high-speed Universal Serial Bus (“USB”) protocol. Upon sampling, by a first input deserializer, first two samples of data signals carried by the P-channel in accordance with a first clock signals clocking twice as fast as the data rate of the P-channel, a second input deserializer is used to sample the second two samples of data signals transmitted by the N-channel in accordance with a second clock signal running twice as fast as the data rate of the N-channel with a ninety (90) degree phase shift. The method subsequently forwards the data signals to one or more configurable logic blocks (“LBs”) in FPGA.
