Abstract
Systems and methods for managing fast to slow links in a bus fabric. A pair of link interface units connect agents with a clock mismatch. Each link interface unit includes an asynchronous FIFO for storing transactions that are sent over the clock domain crossing. When the command for a new transaction is ready to be sent while data for the previous transaction is still being sent, the link interface unit prevents the last data beat of the previous transaction from being sent. Instead, after a delay of one or more clock cycles, the last data beat overlaps with the command of the new transaction.
