Abstract: Power consumption may be reduced in a media device including a first processor coupled to the non-volatile memory, either directly or indirectly, allowing the first processor to generate a pointer structure. The first processor may also be coupled, either directly or indirectly to a memory space, allowing the first processor to write the pointer structure in the memory space. The media device includes a second processor, such as a DSP/SHW or peripheral processor, and may be also be coupled, either directly or indirectly to the memory space, allowing the second processor to retrieve a block of media data from the non-volatile memory. Retrieval of the block of media data may be read directly from the non-volatile memory, or in some cases, the media data being retrieved may be parsed. The media data may be an audio file data, video file data, or both.

Abstract: An apparatus and method that allows a layer 2 “spanning” switch to switch data packets between subnets based upon layer 3 packet addresses. The “spanning” switch on a subnet can offer itself as a destination for data packets crossing to another subnet. Through a configuration process, a layer 2 switch is taught how to forward data packets between two stations on different subnets. The switch can then teach the two stations how to communicate via the layer 2 switch. The layer 2 switch is allocated a “virtual” IP address on each subnet for each station that wants to be involved in cross-subnet communications.

Abstract: A high performance bus and bus interface device for interconnecting numerous devices without using dedicated high current drivers at each device. The bus is synchronous and divided into a plurality of primary local busses and at least one global bus. Data can be transferred from a first device over a first primary local bus through a first global transceiver, over the global bus to a second global transceiver, and then to a second device through a second primary local bus. The bus is driven to a known state at the end of each burst of data transmitted by a device, before the bus is relinquished to another device. Buffers are provided in each device on the primary local bus which can be accessed by other devices.
