摘要： An integrated data processing platform for processing a digital signal that includes a general purpose processor and a digital signal processor (DSP) module. The DSP module recovers digital data from a digital signal utilizing a sequence of DSP operations selected by the general purpose processor. The general purpose processor processes the digital data recovered by the DSP module, but is also available to perform general purpose tasks. A shared internal memory array selectively provides information to the DSP module and to the general purpose processor. The information stored in the internal memory array includes operands utilized in the execution of the DSP algorithm and selected instructions and data utilized by the general purpose CPU either for controlling the execution of the DSP algorithm or for executing its own general purpose tasks. While in many applications the data processing system will include an analog front end that converts a modulated input signal received on an analog transmission channel to a corresponding digital signal for processing by the data processing system, the data processing system may also receive the digital signal directly from a digital source.

摘要： A multi-core plastic optical fiber is used for multi-channel communication purposes. An alignment tool comprising a light source, selective filter and a detachable alignment-tube having a guide notch is provided to map the individual cores of a multi-core plastic optical fiber and prepare the connection of optical transceivers to both exposed ends of a pre-cut length of fiber. The alignment method results in a pre-cut length of fiber having alignment-tubes with guide notches secured to both ends. Transceiver guide projections mate to the notches, creating a complete optical multi-path between the transceiver active elements through the fiber cores. An automatic method of assembling optical transmitters to a multi-core fiber and mating optical receivers uses no alignment tools and tubes. This method dictates a specific placement of the optical transmitters in relation to the cores and receivers, assigning each transmitter to a preferred receiver based on detected light signal criteria.

摘要： A communication signal receiver performs a timing adjustment function of sampling with a circuit that also reduces the amount of electromagnetic interference (EMI) emitted from the receiver. The receiver includes an analog front end circuit that samples an input modulated carrier waveform responsive to a sampling clock signal to generate a digitized replica. The timing of the sampling is responsive to a timing signal. The digitized replica is analyzed to determine an appropriate adjustment to the sampling and, thus, to the timing signal. The frequency of the sampling is changed in accordance with the timing signal as adjusted, without adjusting the phase of the sampling. In particular, the frequency of the sampling is changed by removing transitions from an input clock signal to generate the sampling clock signal.
