iVisual

Abstract

iVisual, an intelligent visual sensor SoC integrating 2790fps CMOS image sensor and 76.8GOPS, 374mW vision processor, is implemented on a 7.5mmx9.4mm die with 0.18μm CIS process. The light-in, answer-out SoC architecture avoids privacy problems of intelligent visual sensor. The feature processor and inter-processor synchronization scheme together increase 51% of average throughput. The 205GOPS/W power efficiency and 1.16GOPS/mm2 area efficiency are achieved.
