Abstract:
1. A frequency adapter for synchronizing data transfers between a low-frequency module configured to operate at a first frequency and a high-frequency module configured to operate at a second frequency, the second frequency being higher than the first frequency, comprising: a low-to-high frequency synchronization unit configured to receive a plurality of data bursts from the low-frequency module, each of the plurality of data bursts including a plurality of data packets, to store the plurality of data packets in a buffer, and to provide a signal indicative of whether the buffer is empty; an end of burst (EOB) unit configured to track a number of the plurality of data bursts stored in the buffer and to provide an EOB-enabled signal when the number is greater than zero; a first logic device configured to provide a valid fast signal based on the signal and the EOB-enabled signal; and a second logic device configured to provide a POP signal based on the valid fast signal and an acknowledgement (ACK) signal, the ACK signal being indicative that the high-frequency module is ready to receive data, wherein the low-to-high frequency synchronization unit is further configured to transfer the plurality of data packets from the buffer to the high-frequency module based on the POP signal.
