Abstract :
iVisual, an intelligent visual sensor SoC integrating 2790fps CMOS image sensor and 76.8GOPS, 374 mW vision processor, is implemented on a 7.5 mm times 9.4 mm die with 0.18 mum 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.
