The Alternate Architecture (AA) represents CSC’s newest generation analog image processor (AIP) and realizes the concept of an Integrated Sensor Processor (ISP). The AA-ISP advances the programmable spatial filtering capability of earlier resistive grid processors by including multiple programmable isotropic & oriented anisotropic lowpass spatial filters to be combined within a single chip and providing individual filter response gain weighting and summation for performing complex spatial filtering operations. The AA-ISP also includes multiple programmable lowpass, bandpass, and highpass temporal filtering processing which can be optionally combined in parallel or in series with the output from the spatial filters. All spatial, temporal or spatio-temporal filtering operations are performed in the analog domain under digital supervisory control. This third generation is a dramatic advancement over previous generations which implemented a single lowpass spatial filter or a single bandpass temporal filter as separate devices.
