摘要

建立了海马结构功能特性的非线性模型。所提出的硬件实现的架构具有与海马解剖结构高度相似的拓扑结构,其组件的动态特性基于单个海马神经元的实验表征。模拟细胞神经网络的设计方案得到了广泛的应用。采用1-/spl mu/m的CMOS技术,设计了5/spl次/5的神经元阵列及其测试模块。根据SPICE-3电路模拟器,每个记忆4个时间单位的神经元的响应时间约为0.5 /spl mu/sec。

VLSI implementation of the hippocampus on nonlinear system model
The nonlinear model of the functional properties of the hippocampal formation has been developed. The architecture of the proposed hardware implementation has a topology highly similar to the anatomical structure of the hippocampus, and the dynamical properties of its components are based on experimental characterization of individual hippocampal neurons. The design scheme of a analog cellular neural network has been extensively applied. By using a 1-/spl mu/m CMOS technology, the 5/spl times/5 neuron array with some testing modules has been designed for fabrication. According to the SPICE-3 circuit simulator, the response time of each neuron with memorizing 4 time units is around 0.5 /spl mu/sec.<>
