Main research

Power-efficient Neuro-Inspired Architectures/Chips with Fault-tolerant Scalable Interconnect for learning in Networks of Spiking Neurons

The neuro-inspired technology based on spiking neural network (SNN) is one of the efficient solutions for brain-inspired cognitive computing in both learning and inference tasks.  Hardware implementations of spiking neural network systems are power-efficient and effective methods to provide cognitive functions on a chip compared with the conventional stored-program computing style.  In SNN based systems, there is no global clock; the neurons only fire when they have reached an activation level. The challenges that need to be solved toward building such a spiking-neuron computing paradigm include building a small-size massively parallel architecture with efficient neuro-coding schemes, robust neuron on-chip interconnect, and lightweight on-chip learning algorithms. 
The goal in this project is to research and develop an ultra-low-power neuro-inspired spiking massively multicore Chip/SoC based on new deep neuronal algorithms and scalable reconfigurable interconnects. We are also investigating the computational properties of neural processing systems by developing new systems that emulate the principles of computation in the neural systems. We are researching and developing FPGA and ASIC Chips/SoCs for vision and learning for implementation in adaptive architecture/systems, cognitive IoT, and autonomous vehicles.
