supportclockfrequenciesupto100MHzandhavereadaccesstimesasfast
as 6.5ns. Two independent 256/512/1,024 x 36 dual-port SRAM FIFOs on

eachportmaybypasstheFIFOsviatwo36-bitmailboxregisters.Eachmailbox
register has a flag to signal when new mail has been stored.
These devices are a synchronous (clocked) FIFO, meaning each port
employsasynchronousinterface.Alldatatransfersthroughaportaregated

each port are independent of one another and can be asynchronous or
coincident. The enables for each port are arranged to provide a simple
