The next jump in processor capabilities may come from number crunching rather than from micron splitting.
A new twist on age-old logarithms may hold the key to faster computer microprocessors. An improved approach to logarithmic arithmetic is finally allowing it to compete with current algorithms used in the central processing units of computers.
Previous processor speeds largely owed their advances to new chip designs. Engineers constantly design chip architectures to permit operation at higher speeds. Similar advances have been achieved by shrinking the semiconductor’s detail resolution progressively to below 1 micron.
