1. An apparatus for controlling an asynchronous First-In-First-Out (FIFO) memory comprising an dual port FIFO memory having a read port and a write port for respectively reading out and writing in data at different operation frequencies, a pair of n-bit circular Gray code counters for handshaking read-out and write-in operation frequencies in the dual port FIFO memory and an n-bit overflow binary counter for accumulating overflows of the pair of n-bit circular Gray code counters, wherein n is any integer more than one.
