Weighted Spintronic-Nano-Oscillator-based Neuromorphic Computing System Assisted by laser for Cognitive Computing


The brain is a highly complex, high performance and low energy computing system due to its massive parallelism and intertwined network, which outperforms the current computers by orders of magnitudes, especially for cognitive computing applications. A large effort has been made into understanding the computing and mimicking the brain into an artificial implementation, so-called neuromorphic computing that has received much attention thanks to the advances in novel nanoscale technologies. The current implementation of the neuromorphic computing systems (NCS) using Complementary Metal-Oxide-Semiconductor (CMOS) technologies has 5-6 orders of magnitude lower performance (operation/sec/Watt/cm3) compared to the brain. Spintronic devices, using the spin of the electron instead of its charge, have been considered one of the most promising approaches for implementing not only memories but also NCSs leading to a high density, high speed, and energy-efficiency. The main goal of SpinAge is to realize a novel NCS enabling large-scale development of brain inspired devices outclassing the performance of current computing machines. This will be achieved by the novel structures using spintronics and memristors, on-chip laser technology, nano-electronics and finally advanced integration of all these technologies. We expect this unprecedented combination of emerging technologies will lead to at least 4-5 orders of magnitude better performance than the state-of-the-art CMOS-based NCSs.
