Abstract:
An inner loop synchronization component for receiving data transmitted to the inner loop synchronization component on the falling and leading edges of a strobe signal and for synchronizing the data with a clock signal, the clock signal having a clock cycle, the inner loop synchronization component comprising:a first data transfer unit, the first data transfer unit comprising logic configured to capture the data transmitted on the falling edge of the strobe signal and logic configured to delay the captured data a predetermined number of cycles of the clock before outputting the captured data from the first data transfer unit;a control unit, the control unit detecting the falling edge of the strobe signal and generating a timing signal that is derived from the strobe signal, wherein the timing signal is utilized by the inner loop synchronization component to capture the data transmitted on the rising edge of the strobe signal; anda second data transfer unit, the second data transfer unit comprising logic configured to capture the data transmitted on the rising edge of the strobe signal, the second data transfer unit receiving the timing signal generated by the control unit and utilizing the timing signal to capture the data transmitted on the rising edge of the strobe signal, the second data transfer unit comprising logic configured to delay the data captured by the second data transfer unit a predetermined number of cycles of the clock before outputting the captured data from the second data transfer unit.
