受脊椎动物视网膜视觉多敏感模型的启发，利用信号处理工具，设计了一种二维CMOS VLSI芯片，提取相应的场景属性，并成功进行了测试。根据内部参数的不同，这个早期视觉系统的原型对边缘、对比和运动很敏感。亚阈值模拟VLSI技术已被用于设计这种低功耗和快速的硅视网膜。重点介绍了该芯片的测试和仿真结果。
Inspired by a visual multi-sensitive model for the vertebrate retina, by using signal processing tools, a two-dimensional CMOS VLSI chip, extracting the appropriate properties of the scene, is designed and then successfully tested. Depending on the internal parameters, this prototype of an early vision system is sensitive to edges, contrasts and motion. Subthreshold analog VLSI techniques have been used to design this low-power and fast silicon retina. Tests on the chip and its simulations results are emphasized.
