ABSTRACT:
A desired FIFO buffer fill level is continuously derived during mapping or demapping of plesiosynchronous data signals into synchronized data signals, or vice-versa. One of j predefined integer values Iiis repetitively consecutively produced during each consecutive one of j FIFO buffer write clock cycles, where i=1, . . . , j and where j and the integer values Iiare selected such that∑i=1j⁢⁢Iijclosely approximates the number of bits read from the FIFO buffer per FIFO buffer write clock cycle. During each kthconsecutive FIFO buffer write clock cycle, a Bits_Read value Ik+Ik-1is produced where k=1, . . . , p; a Bits_Written value is produced; a Gap_Pattern value is derived by subtracting the Bits_Read value from the Bits_Written value; and, the Gap_Pattern is added to a predefined value representative a FIFO buffer center fill level to produce the desired FIFO buffer fill level.
