    摘要: A circuit with an interface, a transmit data register coupled to the interface, a storage device coupled to the transmit data register and including a plurality of storage locations, each storage location adapted to store a data unit, and a serial register coupled between the storage device and an output. The circuit also includes a CRC generation circuit having an input coupled between an output of the transmit data register and the storage device. The CRC generation circuit includes a first CRC generation block for providing a CRC in response to an X-bit data unit and an X-bit polynomial and a second CRC generation block with a collective X-bit input for providing a CRC in response to an X-bit data unit and a 2X-bit polynomial in a single clock cycle and a 2X-bit data unit and a 2X-bit polynomial in two clock cycles.

    摘要: One or more link training signals are received, including instances of a link training pattern, on a plurality of lanes of a physical link that includes at least one valid lane and a plurality of data lanes. The plurality of lanes are trained together using the link training signals to synchronize sampling of the valid lane with sampling of the plurality of data lanes. An active link state is entered and a valid signal received on the valid lane during the active link state. The valid signal includes a signal held at a value for a defined first duration and indicates that data is to be received on the plurality of data lanes in a second defined duration subsequent to the first duration. The data is to be received, during the active link state, on the plurality of data lanes during the second defined duration.

    摘要: An FPGA-based interface signal remapping method, relates to the technical field of nuclear power system, and solves the technical problems of poor reliability, readability and debuggability in the prior art. The method comprises dividing an internal programmable logic of an FPGA chip into two independent modules, with one module being an I/O module and the other module being a Core module, using the I/O module to process signal excursion occurring when an external signal is input to or output from the FPGA chip, signal collision caused by line multiplexing, metastable state in a data transmission process, and a data transmission error between asynchronous clock domains, using the Core module to implement logical processing and computing; and introducing a master clock signal outside the FPGA chip into the FPGA chip through a global clock pin of the FPGA chip. The method provided in the invention is suitable for a nuclear power protection system platform.

    摘要: A registered synchronous FIFO has a tail register, internal registers, and a head register. The FIFO cannot be pushed if it is full and cannot be popped if it is empty, but otherwise can be pushed and/or popped. Within the FIFO, the internal signal fanout of incoming data circuitry and push control circuitry and is minimized and remains essentially constant regardless of the number of registers of the FIFO. The output delay of the output data also is essentially constant regardless of the number of registers of the FIFO. An incoming data value can only be written into the head or tail. If a data value is in the tail and one of the internal registers is empty, and if no push or pop is to be performed in a clock cycle, then nevertheless the data value in the tail is moved into the empty internal register in the cycle.
