Processing apparatus in the form of a parallel processing configuration having a plurality of processors and at least one shared memory that is shared between the processors. Each processor is operated at a clock speed that is lower than the clock speed of the memory.

Processing apparatus and methods

A circuit is for sampling an analog input signal that receives and samples an analog input signal. Sampling circuitry is clocked at a sampling frequency and samples the analog input signal at a rate corresponding to the sampling frequency. The sampling circuitry includes at least one pulse density modulator that includes a comparator configured to be clocked at the sampling frequency, to provide bandpass sampling of the analog input signal at the sampling frequency, and to produce a corresponding pulsed output that is pulse density modulated based on the analog input signal.

Sampling circuitry

A modulator circuit includes a plurality of signal processing branches, each branch having a modulator for performing a delta-sigma modulation of a respective data stream portion in order to generate a modulated signal. The modulator circuit receives an input data stream having a carrier frequency; splits the input data stream into a plurality of data stream portions. Delta-sigma modulation is performed in each branch on a respective data stream portion. The respective modulated signals from each branch are combined to form an output signal for outputting at the carrier frequency.
