High-Performance FPGA Implementation of Fully Connected Networks of SAM Neurons

Neuromorphic computers have been presented as alternatives to traditional von Neumann systems. Neuromorphic systems mimic neural structures of the human brain to make the energy-efficient and high-performance computations. This paper proposes high-speed with no DSP resources FPGA implementation of the SAM neuron model and its fully connected networks with random synaptic weights. The synthesis reports of the implemented SAM neuron with 50, 100, 500, 1000, 2000, 4000, 6000, and 8000 random inputs have been presented. Also, the results of the synthesized fully connected populations comprising 50, 100, 500, 1000, and 1500 SAM neurons have been reported. Accordingly, the FPGA synthesis results of the proposed spiking neuron and networks are noteworthy compared to the state of the arts in terms of performance and DSP resources.
