Buffering techniques for rapid processing of samples of signals modulated with periodic waveforms

摘要

Apparatus having corresponding methods and non-transitory computer-readable media comprise: a sampler configured to sample a signal, wherein the signal is modulated with a waveform having a known period, wherein the sampler obtains K samples in each period, and wherein each of the samples is N bits long, wherein K is an integer greater than 0, and N is an integer greater than 1; a memory bank, wherein the memory bank has M columns and K rows, wherein each column is N bits wide, and wherein M is an integer greater than 0; a write controller configured to write the samples to the memory bank in column order; a read controller configured to read the samples from the memory bank in row order; and an integrator configured to integrate the samples read from the memory bank, wherein the integrator provides a respective integration result for each row.
