Abstract :
A 25 MHz 5×7 spatial filter chip has been developed using CMOS 2 μm process for realtime image processing. The filtering coefficients are specified in a 12-bit floating-point format for higher precision arithmetic. Each multiplier has three coefficient registers for changing the coefficient values in realtime. It contains about 71000 transistors on a 11.7×13.3 mm2 die
