Stephen Byram Furber CBE FRS FREng (born 21 March 1953) is a British computer scientist, mathematician and hardware engineer, currently the ICL Professor of Computer Engineering in the Department of Computer Science at the University of Manchester, UK. After completing his education at the University of Cambridge (BA, MMath, PhD), he spent the 1980s at Acorn Computers, where he was a principal designer of the BBC Micro and the ARM 32-bit RISC microprocessor. As of 2018, over 100 billion copies of the ARM processor have been manufactured, powering much of the world's mobile computing and embedded systems. In 1990, he moved to Manchester to lead research into asynchronous systems, low-power electronics and neural engineering, where the Spiking Neural Network Architecture (SpiNNaker) project is delivering a computer incorporating a million ARM processors optimised for computational neuroscience.
