摘要： A memory controller is provided to increment a source timestamp count responsive to a clock signal. Further, the memory controller associates the source timestamp count to a respective word for each endpoint in a plurality of endpoints. The memory controller transmits the received clock signal, a respective data word, and an associated source count to each endpoint. Each endpoint increments a destination count responsive to the clock signal. Each endpoint further transmits its respective word to an external memory responsive to the destination count being greater than or equal to the associated source count by a threshold margin.

摘要： A memory controller is provided that drives data and a corresponding first data strobe to a plurality of endpoints. Each endpoint is configured to register the received data from the memory controller responsive to the first data strobe and then to re-register the received data responsive to a second data strobe. A clock synchronization circuit functions to keep the received first data strobe at one of the endpoints sufficiently synchronous with the second data strobe.

摘要： A clock synchronization circuit includes a multi-phase clock generator to generate a plurality of delayed clocks, each delayed clock having a unique delay with regard to a source clock. The clock synchronization circuit further includes a selection circuit that selects one of the delayed clocks according to a phase error to form a local clock driven into a local clock path and received at the clock synchronization circuit as a received local clock. The selection circuit determines the phase error by comparing the received local clock to a reference clock.
