First-in-first-out buffer

Abstract

Disclosed aspects relate to a first-in-first-out (FIFO) buffer. The FIFO buffer may include an input interface to receive a set of data payloads. The FIFO buffer may include a set of buffer entry elements to store the set of data payloads. The FIFO buffer may include a set of status indicators to indicate a set of statuses of the set of buffer entry elements with respect to the set of data payloads. The FIFO buffer may include an output interface for release of the set of data payloads.

What is claimed is: 
     
         1 . A first-in-first-out (FIFO) buffering method, comprising:
 receiving, using an input interface, a set of data payloads;   storing, using a set of buffer entry elements, the set of data payloads; and   establishing, using a set of status indicators, a set of statuses of the set of buffer entry elements with respect to the set of data payloads;   releasing, using an output interface, the set of data payloads;   communicating, without an interrupt, a plurality of data payloads of the set of data payloads; and   modifying, using the set of status indicators, the set of statuses of the set of buffer entry elements with respect to the set of data payloads;   wherein the set of status indicators includes a status register which indicates the set of statuses of the set of buffer entry elements with respect to the set of data payloads, further includes:
 shifting, in response to a release of a single data payload, a set of register values of the status register by a single position.
