  • Patent number: 8331330
    Abstract: 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.

  • Publication number: 20090234716
    Abstract: One or more embodiments of the program are directed to a plurality of methods for monetizing online personalized beauty product selections utilizing a technology for content-targeted Internet advertising on a virtual makeover website. Methods comprise: (1) categorizing facial features to select product advertisements for co-branding in a product palette; (2) an auction for webpage advertisement placements related to a user's facial features; (3) transforming a makeover “look” to advertise alternative products to produce the new look under different lighting conditions; (4) a gifting system to allow sale and gifting of products used to produce a makeover, where the makeover image may be packaged with the selected products in a gift package; and (5) recapturing users who would cancel a sale with an offer of less expensive comparable products.

  • Patent number: 7046701
    Abstract: A composite signal has two components, each carrying a stream of information that may be digital. In one application of a method according to an embodiment of the invention, at least one of the components is delayed such that a time relation between the streams of information is altered. The components are transferred via a common signal path such that upon transfer, the original time relation between the streams of information may be restored.

  • Patent number: 6999500
    Abstract: A spreading system according to an embodiment of the invention spreads two data signals. The system produces a filtered signal that is based on one of the data signals and an output signal that is based on both of the data signals. In one example, a spreading system is used to perform QPSK spreading of two data signals, including separate processing of the two data signals, in a practical manner. Such separate control may include filtering and/or gain control.

  • Patent number: 6820103
    Abstract: A system for digital filtering includes a set of logic gates, a state storage, and a multiplexer. The state storage includes two or more storage banks and may also include combinatorial logic and/or at least one lookup table. In one application, a filtering operation according to a finite-impulse-response filter coefficient vector is performed without runtime multiplications. Applications to symmetric and antisymmetric filter coefficient vectors are described, as well as applications to filter coefficient vectors of arbitrary odd or even length.

  • Patent number: 6687870
    Abstract: Interleavers are used in data transmission and storage applications to introduce diversity into a data stream, thereby making adjacent symbols more independent with respect to a transfer environment of variable quality. Conventional interleavers require storage in whole units of data blocks. This storage requirement complicates implementations for applications where available circuit area is limited and data rates and block sizes are large. A novel interleaver produces an interleaved data block using storage space that is only a fraction of the size of the input data block.

  • Patent number: 6615341
    Abstract: A digital signal processor (DSP) employs a variable-length instruction set. A portion of the variable-length instructions may be stored in adjacent locations within memory space with the beginning and ending of instructions occurring across memory word boundaries. The instructions may contain variable numbers of instruction fragments. Each instruction fragment causes a particular operation, or operations, to be performed allowing multiple operations during each clock cycle. The DSP includes multiple data buses, and in particular three data buses. The DSP may also use a register bank that has registers accessible by at least two processing units, allowing multiple operations to be performed on a particular set of data by the multiple processing units, without reading and writing the data to and from a memory. an instruction fetch unit that receives instructions of variable length stored in an instruction memory. An instruction memory may advantageously be separate from the three data memories.

  • Patent number: 6535562
    Abstract: In applications employing phase-shift keying modulation, a phase rotator as disclosed herein is used to rotate the constellation of signal vectors before carrier modulation in order to maximize modulator output power. Such a rotator may be applied in the digital domain (to complex signals having either binary-valued or multi-valued components) or in the analog domain.

  • Patent number: 6516360
    Abstract: A need to store data between a producing stage and a consuming stage commonly arises in digital processing applications. However, factors such as fabrication process limitations and circuit area constraints may restrict the amount of available storage. A novel method and apparatus for data buffering are disclosed which use less data storage than would be required by double buffering techniques.
