A method and apparatus for performing complex mathematical calculations. The apparatus includes a multicore processorwhere the coresare connectedinto a net with the processors on the peripheryprimarily dedicated to input/output functions and distribution of tasks to the central processors-of the net. The central processors-perform calculations substantially simultaneously, far exceeding the speed of conventional processors. The method, which may be implemented by an instruction set to the processor nodes, informs the processor nodes how to divide the work and conduct the calculations. The method includes steps dividing the data into subsetsdirecting the subsets to predetermined nodes, performing the calculationsand outputting the results

Described is a miniaturized satellite transceiver for communicating with a Global Positioning System (GPS) satellite and a communications satellite. The miniaturized satellite transceiver includes an integrated GPS receiver configured to receive communications from the GPS satellite, a satellite modem configured to transmit and receive communications from the communications satellite, and an operating system. The miniaturized satellite transceiver is installable in a hand-held device, a mobile satellite transceiver system, or an in-flight transceiver and locator system.

An improvement in sampling a high frequency input analog signal and converting it to a digital output signal is disclosed. This is accomplished by using a multitude of analog-to-digital converters in conjunction with a distributed sampling system. This combination of multiple converters and a distributed sampling system allows use of conventional device processing, such as that of 0.18 micron silicon, and also provides accurate sampling of very high frequency input signals. The distributed sampling system provides multiple samplings of the input signal by using multiple ADCs for multiple samplings, wherein each sampling is sequentially offset a fixed amount of time from the most recent preceding sampling. Each ADC has a designated central processing unit (CPU) to obtain sufficient data transfer capabilities. The samplings from the multitude of ADCs are a series of sequential digital output values. The digital output values could be the result of samplings all at the same frequency, or at different frequencies. Types of distributed sampling systems include a multitude of elongated trace patterns interconnected in series, a multitude of inverter pairs interconnected in series, a specific permittivity material device, and a sequencer or multiplier. A second enhanced sampling system includes a variable sized aperture window, wherein a width of a sample pulse is narrowed through a variable clock mechanism to produce a faster sampling rate. This variable sized aperture window system can be used by itself, or in combination with any of the presently described multiple ADC distributed sampling systems.

The distributed sampling system provides multiple samplings of the input signal by using a different ADC for each sampling, wherein each sampling is sequentially offset a certain amount of time from the most recent preceding sampling. The samplings from the multitude of ADCs are combined to form a single contiguous digital output signal. Types of distributed sampling systems include a multitude of elongated trace patterns interconnected in series, a specified permittivity material device, and a sequencer or multiplier.
