Abstract: Various embodiments of the present technology may provide methods and apparatus for repetitive histogramming. The apparatus may provide a limited number of physical bins to perform multiple histograms on a total number of virtual bins. The apparatus may provide a single physical bin that is used to sweep over the total number of virtual bins.

Abstract: Various embodiments of the present technology may provide methods and apparatus for region of interest histogramming. The apparatus may use a state machine in conjunction with a memory to generate a first histogram having a fixed number of bins over a first range and generate a second histogram having the fixed number of bins over a region of interest selected based on the first peak of the first histogram.

Abstract: Methods and apparatus for selective histogramming are configured to generate a plurality of histograms over a number of phases using a number of physical bins, wherein the range of a first histogram is greater than a range of a second, subsequent histogram, and wherein each physical bin of the first histogram is defined by a number N of codes and each physical bin of the second histogram is defined by a number M of codes, where M is less than N.

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.
