A bio-inspired model for an analog programmable array processor (APAP), based on studies on the vertebrate retina, has permitted the realization of complex programmable spatio-temporal dynam- ics in VLSI. This model mimics the way in which images are pro- cessed in the visual pathway, rendering a feasible alternative for the implementation of early vision applications in standard tech- nologies. A prototype chip has been designed and fabricated in a 0.5(cid:22)m standard CMOS process. Computing power per area and power consumption is amongst the highest reported for a single chip. Design challenges, trade-o(cid:11)s and some experimental results are presented in this paper.
