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

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 a gigabit ethernet IP telephone chip with integrated security module

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.

Method and system for a gigabit ethernet IP telephone chip with 802.1p and 802.1Q quality of service (QoS) functionalities

A semiconductor memory, such as an SRAM, is described that accommodates smaller read/write accesses in one mode of operation and larger read/write accesses in a second mode of operation, wherein power is conserved during the smaller accesses. Methods of using such a semiconductor memory are also described.

Power saving semiconductor memory

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.

Method and system for a gigabit Ethernet IP telephone chip with integrated DDR interface

Methods and systems for processing data are disclosed herein and may comprise receiving packetized data via at least one input port in an 802.1p and 802.1Q QoS compliant Ethernet switch integrated within a single gigabit Ethernet IP telephone chip that processes multiple voice channels. A priority class may be assigned by the 802.1p and 802.1Q compliant QoS Ethernet switch to at least a portion of the received packetized data. The received packetized data may be processed by the 802.1p and 802.1Q QoS compliant Ethernet switch based on the assigned priority class. The priority class may comprise a high priority class and/or a low priority class. If the priority class comprises a high priority class, the portion of the received packetized data may be buffered in a high priority buffer integrated within the 802.1p and 802.1Q QoS compliant Ethernet switch.
