Synchronous digital implementation of the AER communication scheme for emulating large-scale spiking neural networks models

摘要

In this paper we shall present a fully synchronous digital\udimplementation of the Address Event Representation\ud(AER) communication scheme that has been used in the\udPERPLEXUS chip in order to permit the emulation of\udlarge-scale biologically inspired spiking neural networks\udmodels. By introducing specific commands in the AER\udprotocol it is possible to distribute the AER bus among a\udlarge number of chips where the functionality of the\udspiking neurons is being emulated. A careful design of the\udAER encoder module using compact Content Addressable\udMemories (CAMs) allows for a feasible realization of\udlarge-scale models.
