Abstract
Methods and systems for processing data are disclosed herein and may comprise processing data via a single gigabit Ethernet IP telephone chip integrated within a gigabit Ethernet IP telephone. At least a portion of the processed data may be communicated to an off-chip DDR memory within the gigabit IP telephone via an on-chip DDR memory interface integrated within the gigabit IP telephone chip. The data may be acquired from the off-chip DDR memory via the DDR memory interface for the processing. A request to process the data may be received by the gigabit Ethernet IP telephone chip. The request for processing the data may comprise a Memory Read command, a Memory Write command, a Memory Write with Reply command, a Memory Swap command, an Input/Output (I/O) Read command, an I/O Write command, and/or an I/O Write with Reply command.
