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.

Efficient low power retrieval techniques of media data from non-volatile memory

An apparatus and method that allows a layer,&ldquo;spanning&rdquo; switch to switch data packets between subnets based upon layer,packet addresses. The &ldquo;spanning&rdquo; switch on a subnet can offer itself as a destination for data packets crossing to another subnet. Through a configuration process, a layer,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,switch. The layer,switch is allocated a &ldquo;virtual&rdquo; IP address on each subnet for each station that wants to be involved in cross-subnet communications. More particularly, the invention includes a method for switching data packets between subnets of a network having frame and packet addresses, comprising the steps of: configuring a switching device coupled to each subnet to have a virtual packet address on each subnet associated with a packet address of a station on another subnet; providing a designated station on each subnet with the virtual packet address on such subnet and with an address for the associated station on another subnet; providing a frame address of a destination station on another subnet in response to requests from a designated station on a subnet relating to transmitting data packets to the destination station; and switching data packets from such designated station to the destination station through the switching device in response to the presence of the frame address in such data packets. The invention includes related apparatus and computer programs.

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. Buffer management includes: (1) determination by each transmitting device of buffer availability at each receiving device; (2) 'claiming' use by the transmitting device of a buffer in the receiving device for transfers from the transmitting device, including locking out other devices from writing to that buffer; (3) capability of the transmitting device to move received data to the buffer in the receiver; and (4) notification to all devices that the transfer is complete. The bus is used to transfer data between ports of a LAN bridge or switch. A dedicated lookup bus allows address lookup logic to be accessed without arbitrating for the data bus. A distributed CAM is used to perform address lookup functions.
