Abstract: A mobile device (10) comprises a receiver and a coherent integrator (104), wherein the receiver is configured to receive a first signal from a satellite, the first signal including a navigation message. The coherent integrator is configured to coherently integrate first signal samples for a particular coherent integration interval. When the coherent integration interval straddles a data boundary of the navigation message, the coherent integration is divided into a section before the data boundary of the navigation message and a section after the data boundary of the navigation message

Abstract: One or more loadable PN generators are controlled by a DSP or microprocessor in conjunction with a free-running counter which maintains a reference offset count. The PN generator will typically be part of a finger or searcher. Each PN generator is comprised of a loadable linear feedback shift register (LFSR) or its equivalent, a loadable counter for maintaining an index of the state of that particular PN generator, and a slew control device capable of receiving a slew command and controlling the LFSR and index counter to enact an advance or a retard of a certain offset distance. The speed increase is effected by DSP control. A table of LFSR states and corresponding index numbers are stored in memory. These LFSR states will subdivide the tot al possible number of possible states. It is advantageous to evenly space the stored states around the PN circle. The fast slewing is enabled by the DSP in two-step process. First the PN generator is loaded such that it "jumps" to the closest state using the table, then the P N generator's slew control is used to slew the rest of the way.

Abstract: A circuit for digital signal processing calls for the use of a variable length instruction set. An exemplary DSP includes a set of three data buses (108, 110, 112) over which data may be exchanged with a register bank (120) and three data memories (102, 103, 104). A register bank (120) may be used that has registers accessible by at least two processing units (128, 130). An instruction fetch unit (156) may be included that receives instructions of variable length stored in an instruction memory (152). The instruction memory (152) may be separate from the set of three data memories (102, 103, 104).

Abstract: Techniques for fabricating analog and digital circuits on separate dies and stacking and integrating the dies within a single package to form a mixed-signal IC that provides many benefits. In one aspect, the analog and digital circuits are implemented on two separate dies using possibly different IC processes suitable for these different types of circuits. The analog and digital dies are thereafter integrated (stacked) and encapsulated within the single package. Bonding pads are provided to interconnect the dies and to connect the dies to external pins. The bonding pads may be located and arranged in a manner to provide the required connectivity while minimizing the amount of die area required to implement the pads. In another aspect, the die-to-die connectivity may be tested in conjunction with a serial bus interface.

Abstract: A novel and improved method and apparatus for a fast-slewing pseudorandom noise sequence generator is described. One or more loadable PN generators are controlled by a DSP or microprocessor in conjunction with a free-running counter which maintains a reference offset count. The PN generator will typically be part of a finger or searcher. The DSP or microprocessor may assist in other finger or searcher functions as well as the slew function, and can control one or more fingers and/or searchers. Each PN generator is comprised of a loadable linear feedback shift register (LFSR) or its equivalent, a loadable counter for maintaining an index of the state of that particular PN generator, and a slew control device capable of receiving a slew command and controlling the LFSR and index counter to enact an advance or a retard of a certain offset distance.
