Abstract

An imaging system may include a silicon photomultiplier with single-photon avalanche diodes (SPADs). The imaging system may be a LIDAR imaging system with LIDAR processing circuitry. To reduce memory requirements in the LIDAR processing circuitry, a dynamic resolution storage scheme may be used. The LIDAR processing circuitry may include autonomous dynamic resolution circuitry that receives input from a time-to-digital converter (TDC). The autonomous dynamic resolution circuitry may include a plurality of memory banks having different resolutions. Based on the magnitude of the input from the TDC, an appropriate memory bank may be selected. In parallel, an address encoder may select a memory bin based on the input from the TDC.
