Abstract
A plurality of synchronization FIFOs receive input data streams from corresponding transmitting agents. Data is written to the synchronization FIFOs based on write clock signals provided by the corresponding transmitting agents. An arbitration circuit reads data from the synchronization FIFOs based on an asynchronous local clock signal. A minimum number of entries (S) of each synchronization FIFO is specified by a number of entries required to synchronize the stored data to the local clock signal. Smay further be specified by: a number of entries required to store data during a threshold time period that a throughput of the input data streams may exceed a read data throughput enabled by the local clock signal; a number of entries required to store the data during a flow control response time; and a number of entries read from the synchronization FIFO during the threshold time period and the flow control response time.
