TP 2.1: A Foveated Visual Tracking Chip

This chip uses both biological motivation and compact focal-plane processing to solve a real commercial problem such as 2D camera pointing [1]. This system is unique in its use of a spatially variant layout and arbitration between smooth pursuit (in fovea) and acquisition (in periphery) to improve the tracking process (similar to primate visual tracking). Furthermore, with the exception of the motor drivers, little additional circuitry is required for successful visual tracking. A micrograph of the chip is shown in Figure 1, highlighting the two functional regions.
