Patent ID: 8625719

Claim:
A digital signal processing system, comprising: at least one analog-to-digital converter configured to receive a three phase analog waveform and output at least one digital waveform; a first digital signal processor (DSP) configured to interface with an external computer; a second DSP configured to receive the at least one digital waveform and isolate a specified frequency range; a plurality of DSP's configured to extract channel data from specified channels from the specified frequency range and output the channel data extracted from the specified channels; and an arbiter configured to arbitrate data transfers among the first DSP, the second DSP and the plurality of DSP's by managing a master-slave configuration among at least two of the first DSP, the second DSP, and the plurality of DSP's, wherein the master-slave configuration comprises a master DSP configured to have exclusive access to at least one memory of at least one slave DSP relative to other DSP's in the digital signal processing system, wherein: the second DSP is configured to combine the at least one digital waveform into a combined digital waveform and perform high-pass and low-pass filtering of the combined waveform; the three phase analog waveform comprises a time offset three phase waveform having a frequency substantially similar to a power distribution system frequency, the power distribution system frequency substantially either 50 Hz or 60 Hz; and the specified channels including approximately 2-3 mHz of bandwidth and corresponding to at least one endpoint in a power distribution system and the channel data extracted from the specified channels corresponds to data received from an endpoint in the power distribution system.
