Abstract
A receiving device uses an elastic buffer that is wider than the number of data elements transferred in each cycle. To compensate for frequency differences between the transmitter and the receiver, the transmitting device periodically sends a skip request with a default number of skip data elements. If the elastic buffer is filling, the receiving device ignores one or more of the skip data elements. If the elastic buffer is emptying, the receiving device adds one or more skip data elements to the skip request. To maintain the ordering of data despite the manipulation of the skip data elements, two rows of the wide elastic buffer are read at a time. This allows construction of a one-row result from any combination of the data elements of the two rows. The column pointers are adjusted appropriately, to ensure that they continue to point to the next data to be read.
