DSP workload distribution in a power line carrier system

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 specified channels from the specified frequency range and output the extracted channel data;
• and
• an arbiter configured to arbitrate data transfers among the first DSP, the second DSP and the plurality of DSP's;
• wherein:
• the second DSP is configured to combine the at least one waveform into one digital waveform and perform high-pass and low-pass filtering of the at least one 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 extracted channel data corresponds to data received from an endpoint in the power distribution system.
