Abstract :
In this paper, we introduce our CMOS block matrix transform imager architecture (MATIA). This imager is capable of performing programmable matrix operations on an image. The imager architecture is both modular and programmable. The pixel used in this architecture performs matrix multiplication while maintaining a high fill-factor (46%), comparable to active pixel sensors. Floating gates are used to store the arbitrary matrix coefficients on-chip. The chip operates in the subthreshold domain and thus has low power consumption (0.23 mW).
