medical sciences and computer vision, just to name a few. Deep sub-nanosecond timing resolution, in combination with high sensitivity, is becoming increasingly important in a number of imaging methods. Non solid-state devices enabling picosecond time resolution, such as photomultiplier tubes and microchannel plates, have existed for decades. However, cost and size have limited their use to low-scale and scientific applications. In solid-state technology, singlephoton avalanche diodes (SPADs) have become the alternative of choice [1]. Recently, SPADs are even more compelling with the emergence of CMOS implementations [2] and the appearance of multipixel designs [3]-[6]. With the growth of the array size however, it has become increasingly hard to process massive volumes of data from SPAD pixels. To
