Abstract
Satellite positioning system (SATPS) receiver that has a plurality of modes and channels, where a timeline module configures the channels based on the mode of operation of the SATPS receiver and reconfigures the channels if the mode of operation of the SATPS changes.

9. A method of timeline management in a satellite positioning receiver, comprising the steps of:
-
configuring a number of channels in a memory that contains satellite positioning signal data accessed by a signal processing subsystem and a Fast Fourier Transfer (FFT) subsystem; and minimizing stall times of the number of channels in the memory when the signal processing subsystem and the FFT subsystems are accessing the number of channels. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. Computer-readable storage media storing instructions that upon execution by a processor cause the method of timeline management in a satellite positioning receiver to occur, the media having stored instructions that cause the system processor to perform the steps comprising:
-
configuring a number of channels in a memory that contain satellite positioning signal data accessed by a signal processing subsystem and a Fast Fourier Transfer (FFT) subsystem; and minimizing the stall time of the number of channels in the memory. - View Dependent Claims (17, 18, 19, 20, 21, 22)
