Abstract: An interface between an RF processing section and a baseband processing section supports general purpose message transmission as well as satellite positioning system signal sample transmission between the RF processing section and the baseband processing section. The interface includes a bi-directional message interface and a data interface. The message interface supports transmission of power control messages to the RF processing section to provide detailed control over activation or de-activation of individual blocks of hardware circuitry in the RF processing section.

Abstract: An interface between an RF processing section and a baseband processing section supports general purpose message transmission as well as satellite positioning system signal sample transmission between the RF processing section and the baseband processing section. The interface includes a bi-directional message serial interface and a data serial interface. The complexity of the data serial interface may be minimized by using a single data bit signal line in the data serial interface.

Abstract: Systems and methods are disclosed herein to dynamically vary supply voltages and clock frequencies, also known as dynamic voltage scaling (DVS), in GPS receivers to minimize receiver power consumption while meeting performance requirements. For the baseband circuitry performing satellite acquisition and tracking, supply voltages and clock frequencies to the baseband circuitry are dynamically adjusted as a function of signal processing requirements and operating conditions for reducing baseband power consumption. Similarly, the supply voltage and clock frequency to the processor running navigation software and event processing are dynamically adjusted as a function of navigation performance requirements and event occurrences to reduce processor power consumption.
