From a university spin-off company in the North of England comes a microprocessor that is claimed to be the first to operate directly on numbers that it holds in a logarithmic representation. The device is aimed at applications that involve heavy computation loads, and would essentially replace today's floating-point processors or co-processors. It's designers say that it offers a performance gain in such mathematically-intensive algorithms.
When numbers are represented as logarithms, multiplying or dividing two numbers is carried out by addition or subtraction. Clearly, ...
