摘要： A novel and improved method for performing paging is described. In one embodiment of the invention a searcher is used to detect spread spectrum signals. Samples received RF signals are stored in a sample buffer. During standby mode, the samples are gathered during paging slots assigned to the mobile. A set of searches are performed on the samples, and if pilot signals are detected additional demodulation is performed to detect paging messages. The resulting set of demodulation data may be combined to increase detection. After a page message has been detected, additional demodulation resources may be activated to processes more complete page messages, or other information channels. In one embodiment of the invention, the searcher includes a demodulator to perform quick page detection without the use of finger elements to reduce idle mode power consumption.

摘要： A digital signal processor uses a variable length instruction set. The variable length instructions may be stored in adjacent locations within memory space. The beginning and ending of instructions may, but are not required to, occur across memory word boundaries. Preferably, the variable length instructions contain variable numbers of instruction fragments. Each instruction fragment causes a particular operation (or operations) to be performed, thereby allowing multiple operations to be performed during each clock cycle. This reduces the total number of clock cycles necessary to perform a task.

摘要： 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.

摘要： 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.

摘要： Techniques for efficient searching in asynchronous systems, such as W-CDMA, as well as multi-mode searching, are disclosed. In one aspect, step one and step three search are performed in a single search engine. In another aspect, a search engine is configurable to search the offsets of a slot in step one search, producing sequential hypothesis energies, and peak detecting and sorting those energies. In yet another aspect, the peak detector and sorter are configurable to perform step one searching or step three/multimode searching. Various other aspects of the invention are also presented. These aspects have the benefit of circuit area and search-time efficiency which translate into reduced costs, increased standby time, increased acquisition speed, higher quality signal transmission, increased data throughput, decreased power, and improved overall system capacity.

摘要： A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.
