In 2000 we described a proposal for a logarithmic arithmetic unit, which we suggested would offer a faster, more accurate alternative to floating-point procedures. Would it in fact do so, and could it feasibly be integrated into a microprocessor so that the intended benefits might be realized? Here, we describe the European Logarithmic Microprocessor, a device designed around that unit, and compare its performance with that of a commercial superscalar pipelined floating-point processor. We
