ABSTRACT: Address event representation (AER) is a neuromorphic interchip communication protocol that allows for real-time virtual massive connectivity between huge number neurons located on different chips. When building multichip mutilayered AER systems it is absolutely necessary to have a computer interface that allows (a) to read AER interchip traffic into the computer and visualize it on screen, and (b) convert conventional frame based video stream in the computer into AER and inject it at some point of the AER structure. This is necessary for test and debugging of complex AER systems. Previous work presented several software methods for converting digital frames into AER format. Those methods were not feasible for real-time conversion those days because the processor performance was insufficient. Nowadays, Multicore processor architectures and cache hierarchies have evolved and the performance is much better than Pentium 4 Mobile of those years. In this paper we study frame to AER methods for real-time video applications (40 ms per frame) using modern processor architectures, compilers, and processors oriented for stand-alone applications (mini-PC processors).
