摘要
A method and apparatus are described for controlling depth and power consumption of a first-in first-out (FIFO) memory including a data storage, a FIFO top register, a FIFO bottom register and control logic. The data storage may be segmented into a plurality of data storage segments. The FIFO top register may be configured to generate a first value indicating where a first entry in the data storage is stored. The FIFO bottom register may be configured to generate a second value indicating where a last entry in the data storage is stored. The control logic may be configured to determine which of the data storage segments to activate or deactivate based at least in part on the first and second values, and to monitor an available capacity and a write/read rate of the FIFO memory as data is read from and written to the activated data storage segments.
