Abstract
In one embodiment, the present invention includes a method for receiving at a transceiver from a baseband processor digital control information that includes both event and schedule information, storing the digital control information in a storage of the transceiver, and operating the transceiver according to the event and schedule information.
Claims20
A method comprising:
- receiving digital control information at a transceiver from a baseband processor along a serial signal line, the digital control information including configuration information to configure the transceiver, event information including event codes to identify actions to be taken by the transceiver and schedule information including schedule codes each to identify timing of a corresponding one of the actions to be taken by the transceiver;
- storing the digital control information in at least one storage of the transceiver;
- and
- operating the transceiver according to the event information and the schedule information, including configuring the transceiver using the configuration information, and performing transmit or receive operations on data, including powering up the transceiver and antenna switching using the event information at times according to schedule codes at a timing pattern relative to receipt of a strobe signal, including performing a modulator control operation in the transceiver according to a first event code at a time relative to a previous operation according to a first schedule code, the first schedule code corresponding to a period of time after the previous operation, and performing a ramp operation in the transceiver according to a second event code at a time according to a second schedule code, wherein the second schedule code corresponds to a predetermined number of clock signals of a system clock of the transceiver after the modulator control operation.
1 more element
A transceiver comprising:
- a digital control interface to communicate digital control information between a baseband processor and the transceiver;
- and
- an event storage coupled to the digital control interface to store the digital control information received from the baseband processor, the event storage including:
- a plurality of registers each to store an event having an event code to identify an action to be taken by the transceiver and a corresponding schedule code to identify a time at which the corresponding action is to be taken by the transceiver, wherein the time is relative to a preceding event, the transceiver to perform a modulator control operation according to a first event code at a time relative to a previous operation according to a first schedule code, the first schedule code corresponding to a period of time after the previous operation, and perform a ramp operation according to a second event code at a time according to a second schedule code, wherein the second schedule code corresponds to a predetermined number of clock signals of a system clock of the transceiver after the modulator control operation.
1 more element
A system comprising:
- a transceiver having a digital interface to communicate digital control information between a processor and the transceiver, a control storage coupled to the digital interface to store the digital control information received from the processor, the control storage including a plurality of registers each to store an event having an event code to identify an action to be taken by the transceiver and a corresponding schedule code to identify a time at which the corresponding action is to be taken by the transceiver, wherein the time is relative to a preceding event, wherein the transceiver is to perform a modulator control operation according to a first event code at a time relative to a previous operation according to a first schedule code, the first schedule code corresponding to a period of time after the previous operation, and perform a ramp operation according to a second event code at a time according to a second schedule code, wherein the second schedule code corresponds to a predetermined number of clock signals of a system clock of the transceiver after the modulator control operation;
- a power amplifier coupled to the transceiver;
- an antenna coupled to the power amplifier to transmit and receive information;
- and
- the processor coupled to the transceiver to provide the digital control information to the transceiver.
