摘要： A device includes a key store memory, a rule set memory, a plurality of cryptographic clients, and a key store arbitration module. The key store memory stores a plurality of cryptographic keys and the rule set memory stores a set of rules for accessing the cryptographic keys. A cryptographic client is operable to issue a request to access a cryptographic key(s) and, when access to the cryptographic key is granted, execute a cryptographic function regarding at least a portion of the cryptographic key to produce a cryptographic result. The key store arbitration module is operable to determine whether the request to access the cryptographic key is valid; when the request is valid, interpret the request to produce an interpreted request; access the rule set memory based on the interpreted request to retrieve a rule of the set of rules; and grant access to the cryptographic key in accordance with the rule.

摘要： An encoded signal is modulated to produce a first radio frequency (RF) signal that is transmitted to a client module over a first transceiver channel when a first transceiver module is in a transceive mode. A channel scan is performed when the first transceiver module is in a scan mode. The encoded signal is modulated to produce a second RF signal and that is transmitted over a second transceiver channel when a second transceiver module is in a transceive mode. The first and second RF signals are received over a first and a second transceiver channel respectively and they are combined when the first and the second transceivers are both in the transceive mode.

摘要： A method includes generating an indicator of interference introduced by a transmitter into a spectrum of an output transmit signal outside a target channel of the transmitter. The indicator is generated based on the output transmit signal. The method includes adjusting a power level of the output transmit signal based on the indicator and a predeterminedinterference indicator level. The indicator may indicate a carrier-to-interference (C/I) ratio of the output transmit signal, and the adjusting comprises setting the power level of the output transmit signal to a maximum power level that maintains the C/I ratio of the output transmit signal above the predetermined interference indicator level. The output transmit signal may be based on a radiofrequency output of a power amplifier of the transmitter prior to transmission over a channel and the generating comprises generating a baseband version of the output transmit signal.

摘要： A circuit for use in a multimedia server module includes an encoder module that encodes a multimedia signal to produce an encoded signal that includes a sequence of packets having a packet size. An RF server transceiver module, coupled to the encoder module, produces a channel signal that includes the encoded signal, and wirelessly transmits the channel signal at a link data rate over a wireless communication path to at least one client module. The RF server transceiver module includes a quality of service module that adjusts the packet size based on first RF performance signals determined by the RF transceiver, based on second performance signals received from a client module and/or based on adjustments made to the link data rate.

摘要： A method and apparatus for providing: multimedia services to a local area network includes processing that begins by receiving a plurality of channels from at least one multimedia source. The processing continues by receiving selection requests from at least one client module via a communication path. The processing continues by generating a set of channel select commands from the select request. The processing continues by selecting a set of channels from the plurality of channels based on the set of channel select commands. The processing continues by mixing the set of channels into a stream of channel data. The processing then continues by transmitting the stream of channel data via the communication path to the at least one client module such that each client associated with a client module receives the channel data for the respective channels that they had selected.

摘要： A processing system includes a memory module that includes a register space for storing a plurality of register data in a plurality of registers and secure access data corresponding to the register space. A register arbitration module operates to receive a request to access one of the registers from a client module; retrieve secure access data corresponding to the client to determine if the client is trusted; and to grant the request to access the register if the client is trusted. If the client is not trusted, the register arbitration module retrieves secure access data to determine if the register is non-secured for the client. The register arbitration module grants the request to access the register when the register is non-secured for the client.
