    摘要： An apparatus for reducing storage requirements and for allowing reuse of multiple rake fingers in a spread spectrum system includes a decimation circuit having an associated decimation factor, a memory coupled to the decimation circuit, and an interpolation circuit having an interpolation factor coupled to the memory. The decimation circuit decimates the sampling rate of received data to produce a decimated rate. The received data is stored in the memory at the decimated rate. The decimated rate is later increased by the interpolation circuit by the interpolation factor when the stored data is retrieved from the memory. The memory is a circular buffer or a single port RAM that is accessible by multiple rake fingers substantially simultaneously via selector circuits.

    摘要： A method for designing a time-sliced and multi-threaded architecture comprises the steps of conducting a thorough analysis of a range of applications and building a specific processor to accommodate the range of applications. In one embodiment, the thorough analysis includes extracting real time aspects from each application, determining optimal granularity in the architecture based on the real time aspects of each application, and adjusting the optimal granularity based on acceptable context switching overhead.

    摘要： An architecture and method for dynamic resource allocation and scheduling in a communication device is disclosed herein. The method of controlling hardware resources in a communication device having a processor, a computer readable memory, and at least one hardware resource coupled to each other includes several steps. The first step locates a memory address in the computer readable memory that is associated with a first hardware resource. In the next step, control information associated with the first memory address is transmitted to the first hardware resource for it to be operated. In the last step, a pointer associated with the first address that locates a subsequent address for a subsequent hardware resource, is read.

    摘要： A capacitive touch sensor has a clear top plastic film and graphics or other designs disposed on its reverse side. Only the bare plastic substrate is exposed to the environment and user wear. Non-conductive color inks are used in printing the graphics so that any printed capacitive sensors in contact behind will not be short circuited or desensitized. A silk-screened base color layer with a print-free margin left all around its edges allows a later application of adhesive to grip a more durable surface underneath. Capacitive touch sensors are deposited on a bottom plastic film with silvered conductive inks. The printed capacitive sensors on film are fastened with a silk-screen applied liquid water-based adhesive and face the graphics printed side of the first plastic film. A final overcoat of adhesive is applied to the bare backside of the bottom plastic film for final assembly to a frame or chassis.
