神经网络对脉冲模式处理的兴趣越来越大，这鼓励了分布在多个芯片上的集成和激发神经元的大规模并行网络的硬件实现的发展。地址事件表示（AER）一直被认为是一个方便的传输协议的尖峰基于神经元形态设备。基于AER的系统的一个缺失的、长期需要的功能是从复杂的神经形态系统获取数据并使用合适的数据来刺激它们的能力。我们以软件支持的外围组件互连（PCI）板（PCI-AER板）的形式实现了通用解决方案。我们描述了PCI-AER板的主要特点，以及相关的支持软件。为了展示PCI-AER基础设施的功能，我们展示了一个可重构的多芯片神经形态系统的功能选择性模型的方向调整性能的皮层神经元。
The growing interest in pulse-mode processing by neural networks is encouraging the development of hardware implementations of massively parallel networks of integrate-and-fire neurons distributed over multiple chips. Address-event representation (AER) has long been considered a convenient transmission protocol for spike based neuromorphic devices. One missing, long-needed feature of AER-based systems is the ability to acquire data from complex neuromorphic systems and to stimulate them using suitable data. We have implemented a general-purpose solution in the form of a peripheral component interconnect (PCI) board (the PCI-AER board) supported by software. We describe the main characteristics of the PCI-AER board, and of the related supporting software. To show the functionality of the PCI-AER infrastructure we demonstrate a reconfigurable multichip neuromorphic system for feature selectivity which models orientation tuning properties of cortical neurons.
