  • Patent number: 12261620
    Abstract: An example apparatus includes: controller circuitry configured to: provide switch signals to capacitive digital to analog converter (C-DAC) circuitry, the C-DAC circuitry including switches; configuring the switches into a third configuration begin an Auto Zero (AZ) phase with a third switch in a closed state; configuring the switches into a fourth configuration to repeat the transition of the third switch to the open state corresponding to a first configuration; configuring the switches into a fifth configuration to repeat the transition of a first switch and a second switch to the open state corresponding to a second configuration; configuring the switches into a sixth configuration to repeat the transition of the third switch to the closed state corresponding to a second configuration; and performing an AZ decision with the switches in the sixth configuration.

  • Publication number: 20190005349
    Abstract: This invention transforms a list of feature points in raster scan order into a list of maxima suppressed feature points. A working buffer has two more entries than the width of the original image. Each entry is assigned to an x coordinate of the original image. Each entry stores a combined y coordinate and reliability score for each feature point in the original list. This process involves a forward scan and a backward scan. For each original feature point its x coordinate defines the location within the working buffer where neighbor feature points would be stored if they exist. The working buffer initial data and the y coordinates assure a non-suppress comparison result if the potential neighbors are not actual neighbors. For actual neighbor data, the y coordinates match and the comparison result depends solely upon the relative reliability scores.
