We introduce a memory-efficient method for processing up-the-ramp sampled data to reduce noise and remove cosmic-ray events. The method we describe includes initial processing in the readout electronics (onboard, in the case of a space mission) plus postprocessing downstream. This data processing approach can be used to record or downlink high-quality science data using a small fraction of the bits required to transmit the full data, potentially reducing the volume to 0.01-0.001 of its original size. The onboard component has the advantage that it ``processes as you go,'' reducing the online memory requirements. The processing and memory requirements are modest and are within the scope of current-generation avionics systems. We discuss the requirements and the performance of the algorithm. We also demonstrate the quality of the resulting data.
