iVisual integrates a high-speed CMOS image sensor and vision processor to improve throughput and efficiency.
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.
