Methods and systems for processing Ethernet data are disclosed and may comprise receiving Ethernet data via a single gigabit Ethernet IP telephone chip. A secure application key may be received from a secure server by an OSM integrated within the gigabit Ethernet IP telephone chip for processing the received Ethernet data. The received Ethernet data may be processed by the gigabit Ethernet IP telephone chip based on the received secure application key. A unique security identifier internal to the single gigabit Ethernet IP telephone chip may be communicated off-chip to the secure server. The unique security identifier may identify the single gigabit Ethernet IP telephone chip. The secure server may authenticate the gigabit Ethernet IP telephone chip based on the unique security identifier internal to the single gigabit Ethernet IP telephone chip, prior to the receiving of the secure application key.

Method and system for an electronic device with integrated security module

Methods and systems for an Ethernet IP phone chip are provided. In this regard, data may be received via a first port of an Ethernet switch in the Ethernet IP phone chip, and the port(s) via which the data is forwarded may be determined based on characteristics of the data. The Ethernet switch may receive data from a network via a first port, and communicate the received data to one or more on-chip interfaces via a second port. The on-chip interfaces may process the received data and may communicate video contained in the data to an off-chip video processing device. The Ethernet IP phone chip may receive video data from an off-chip video processing device via one or more on-chip interfaces, packetize the video data into one or more Ethernet packets; and communicate the packet(s) onto a network link via the Ethernet switch.

Method and system for an ethernet IP telephone chip

A voice queue includes a primary queue and a secondary queue. The secondary queue is operable to store voice packets and generate timestamps for the voice packets. The primary queue is operable to receive the voice packets from the secondary queue, store the timestamps for the voice packets, and store sequence numbers for the voice packets.

Voice and data exchange over a packet based network

A method for processing Ethernet data and may include receiving Ethernet data via at least one Ethernet physical interface transceiver (PHY) integrated within a single Ethernet IP telephone chip. At least one secure application key may be received from a secure server by an on-chip security module (OSM) integrated within the Ethernet IP telephone chip for processing the received Ethernet data. The Ethernet IP telephone chip may be authenticated prior to the processing of the received Ethernet data using a security processor integrated within the OSM. The received Ethernet data may be processed by the Ethernet IP telephone chip based on the received at least one secure application key. The at least one secure application key may be communicated only from the secure server to the Ethernet IP telephone chip. The received Ethernet data may include one or both of video data and/or voice data.

Method and system for an Ethernet IP telephone chip

A method for processing data may include receiving packetized data via at least one of a plurality of input ports in an Ethernet switch. Each of the plurality of input ports may be partitioned into a plurality of virtual local area network (VLAN) port domains with an assigned port domain identification (ID) for processing 802.1 Class of Service (CoS) priority and Quality of Service (QoS) packetized data. The Ethernet switch may be integrated within a single gigabit Ethernet IP telephone chip, the received packetized data having assigned at least one priority class. One or more bits in at least one of a plurality of registers in the Ethernet switch may be used to filter at least one ingress frame in the packetized data, based on at least one packet header attribute of the at least one ingress frame.

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.

Method and system for a gigabit Ethernet IP telephone chip with no DSP core, which uses a RISC core with instruction extensions to support voice processing

A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.
