Abstract
Methods and systems for processing data are disclosed and may comprise receiving packetized data comprising voice data and network data via an Ethernet switch integrated within a single gigabit Ethernet IP phone chip. The received packetized data may be processed via a single main processor core integrated within the single gigabit Ethernet IP phone chip. The single main processor core may comprise circuitry that is controlled by an instruction set for handling processing of the voice data for a plurality of voice channels without the use of a separate DSP. It may be determined whether data to be processed by the single main processor core is voice data or network data. If the data to be processed by the single main processor core is voice data, at least one modified instruction may be selected from the modified instruction set for processing the voice data.
