Schon et al from Prophesee published a paper titled "A 320 x 320 1/5" BSI-CMOS stacked event sensor for low-power vision applications" in the 2023 VLSI symposium. This paper presents some technical details about their recently announced GenX320 sensor.
Abstract
Event vision sensors acquire sparse data, making them suited for edge vision applications. However, unconventional data format, nonconstant data rates and non-standard interfaces restrain wide adoption. A 320x320 6.3μm pixel BSI stacked
event sensor, specifically designed for embedded vision, features multiple data pre-processing, filtering and formatting functions, variable MIPI and CPI interfaces and a hierarchy of power modes, facilitating operability in power-sensitive vision
applications.
