Abstract:
System and method for hardware implemented accumulation of waveform data. A digitizer is provided that includes: a circuit, and first and second memory banks, coupled to the circuit. The circuit may be configured to: store a first subset of the waveforms in the first memory bank, accumulate each waveform in a chunk-wise manner, where each chunk has a specified size, thereby generating a first bank sum including a first partial accumulation of the set of waveforms, store a second subset of waveforms in the second memory bank concurrently with the accumulation, and accumulate each waveform of the second subset of waveforms in a chunk-wise manner, thereby generating a second bank sum including a second partial accumulation of the set of waveforms, where the first and second partial accumulations of the set of waveforms are useable to generate an accumulated record of the set of waveforms.
