ARM Inventor Steve Furber on SpiNNaker 1, 2, and Beyond
Professor Steve Furber, co-designer of the ARM architecture and BBC Micro, discusses the SpiNNaker neuromorphic computing platform, explaining its massively parallel, multicast routing design intended to model biological neural networks in real time. He details the transition from SpiNNaker 1, which used software-defined neuron models on ARM cores, to SpiNNaker 2, which adds hardware accelerators for exponentials, random numbers, and matrix operations to support hybrid spiking and artificial neural networks. Furber notes that while SpiNNaker 1 served as a critical simulator for the Human Brain Project, SpiNNaker 2 aims to bridge the gap toward practical, low-power embedded robotics applications.
