我们描述了一个多芯片模拟 VLSI 系统，该系统模拟初级视觉皮层中简单细胞的方向选择性响应。该系统由两个模拟芯片、一个硅视网膜和一个定向芯片组成，模仿大脑中视觉系统的并行和分层架构。系统的空间分辨率为100/spl次/100像素。硅视网膜以类似拉普拉斯-高斯的感受野接收输入图像。视网膜的输出图像被传输到方向选择芯片。两个芯片之间的图像传输是使用模拟信号进行的。定向芯片选择性地聚集硅视网膜的多个像素，模仿了为解释简单细胞的定向选择性感受野而提出的前馈模型。定向芯片并行提供具有不同优选定向的三个输出图像。本研究中使用的模拟多芯片架构可用于模拟初级视觉皮层中高级细胞的反应。
We describe a multi-chip analog VLSI system which emulates the orientation selective response of the simple cell in the primary visual cortex. The system consists of two analog chips, a silicon retina and an orientation chip, which mimic the parallel and hierarchical architecture of the visual system in the brain. The spatial resolution of the system is 100/spl times/100 pixels. The silicon retina receives the input image with a Laplacian-Gaussian-like receptive field. The output image of the retina is transferred to the orientation selection chip. The image transmission between two chips is carried out using analog signals. The orientation chip selectively aggregates multiple pixels of the silicon retina, mimicking the feed-forward model proposed to explain the orientation-selective receptive field of the simple cell. The orientation chip provides three output images with different preferred orientation in parallel. The analog multi-chip architecture used in the present study is useful to mimic the responses of higher order cells in the primary visual cortex.
