Steve Furber is the ICL Professor of Computer Engineering in the Department of Computer Science at Manchester University. Prior to this appointment he was in charge of the hardware development group within the R&D department at Acorn Computers Ltd, and was a principal designer of the BBC Microcomputer and the Acorn RISC Machine (a 32-bit RISC microprocessor for low-cost applications), both of which earned Acorn Computers a Queen's Award for Technology. He also led the team which developed the hardware architecture and VLSI components for the Acorn Archimedes. Since moving to the University of Manchester in 1990 he has established a research group with interests in asynchronous logic design. This group has developed (amongst other things) an asynchronous implementation of the ARM microprocessor based on Sutherland's micropipelines.
