Abstract:
A method and device for managing retransmit operations. The device, includes a FIFO memory unit, a read pointer, a retry pointer and a write pointer. The device is characterized by including a gray code state machine connected to an emulated read pointer logic; whereas the gray code state machine is adapted to provide a gray code word representative of a state of a read logic that comprises the read pointer; whereas the emulated read pointer logic is adapted to process at least one gray code word and to provide an emulated read pointer that tracks a FIFO memory unit entry that stores data that was not accepted; whereas the emulated read pointer logic is connected to a write control logic adapted to control writing operations to the FIFO memory unit in response to the emulated read pointer logic; and whereas the read logic receives a read clock that differs from a write clock provided to the emulated read pointer logic and to the write control logic.
