In this paper, we present an architecture and corresponding analysis for large-scale neuromorphic systems using a digital approach where neurons are abstracted as arithmetic logic units and communication processors. After presenting the architecture, we establish a few basic architectural principles, particularly the scaling of the system to large arrays. We demonstrate the reality of a single chip...
In this paper we present the circuits and simulation results for a silicon neuron which is based on a modified version of the Mihalas-Niebur neural model. This silicon neuron produces 15 of the 20 known neural spiking and bursting behaviors. It has low complexity and reliable matching and can thus be easily integrated into more complex neuromorphic systems. Implemented in a 0.15 mum 1.5 V CMOS process,...
We present the architecture and testing of an address event representation (AER) wireless link that uses ultra wideband (UWB) radio as the physical layer. The wireless protocol layers from high to low level are: AER events, asynchronous handshaking, PRN coding, and UWB transmission. The top three layers are implemented in digital logic in an FPGA, while the UWB physical layer is implemented using...
We present an array of dynamical digital silicon neurons implementing the Izhikevich neuron model. The FPGA based array consists of 32 physical neurons, each time multiplexing the state of 8 virtual neurons, for a total of 256 independent neurons. The neural array operates at 5,000 times faster than real time, performing over 20.48 GOPS (giga operations per second). It is intended for neural simulation...
Impulse or ultra wideband (UWB) radio is a wireless communications method, providing high bandwidth for short range communication. Address event representation (AER) is a communications protocol for conveying information in terms of events and is widely used in neuromorphic systems. Combining the two techniques, we present a method for wirelessly sending AER events between neuromorphic systems. The...
