A method of entering a power conservation state comprises selecting and entering one of a plurality of low power states for the computer system in response to a detected system idle event. The plurality of low power states comprise a first low power state and a second low power state for the computer system. A memory of the computer system is self refreshed during the first low power state. A baseband module of the computer system remains powered, and the memory is accessible to the baseband module during the second low power state. The one low power state is selected depending upon baseband module activity. The method also includes exiting from the one of a plurality of low power states when a wake event is detected.

Low-power states for a computer system with integrated baseband

A modem is disclosed. An embodiment thereof includes: a first interface arranged to connect to a network, a second interface arranged to connect to a host processor on the terminal, an audio interface arranged to connect to an audio processing means and a processing unit arranged to receive a plurality of parameters from the terminal via the second interface. The plurality of parameters are associated with a call established by the host processor to at least one further terminal connected to the network; wherein the processing unit is further arranged to receive input voice data from the audio processing means, process the input voice data in dependence on at least one of said parameters; and transmit the processed input voice data via the first interface to the at least one further terminal over said network during the call in dependence on a further at least one of said parameters.

Communication system and method

A modem for handling notifications received over a network is disclosed. In one embodiment, the modem includes a first interface to connect to a network, a second interface to connect to a host processor on a terminal and a modem processor to receive presence configuration information from the host processor and in response thereto transmit a request comprising the presence configuration information to a presence information store. The modem processor further arranged to receive one or more notifications with presence information from the store based on the presence configuration information in the request. The presence information supplied to the store by one or more further terminals associated with one or more users. The modem processor stores the one or more notifications in a storage means, and in response to receiving a request for presence information from said host processor, supply presence information thereto based on the one or more notifications.

A circuit comprising: clock circuitry for supplying a first faster clock signal to a first circuit portion and a second slower clock signal to a second circuit portion, and varying the relative frequency of the first and second clock signals. Synchronisation logic generates pulses which indicate when to transfer data between the first and second circuit portions. The clock circuitry generates a first control signal at a predetermined time in each cycle of the first clock signal prior to a predetermined edge, and a second control signal at a predetermined time in each cycle of the second clock signal prior to a predetermined edge. A change in the relative frequency is conditional on a coincidence of the first and second control signals. The synchronisation generates the pulses such that there is at least one cycle of the first clock signal between those pulses, and such that there is only one of those pulses per cycle of the second clock signal.
