In contrast to all other microprocessors, which use floating-point for their real arithmetic, the European Logarithmic Microprocessor is the world's first device to use the logarithmic number system for this purpose. Simulation work has already suggested that this can deliver approximately twofold improvements in speed and accuracy. This paper describes the ELM device, and illustrates its operation using an example from a class of RLS algorithms.
