Designing low-power multiprocessor chips Design How-To 2/12/2007 Post a comment
Just 10 years ago, the challenge chip designers faced was to design logic blocks with as few gates as possible to fit all the functions in a target die size. Today, advancements in semiconductor process technologies let designers easily pack millions of gates and complex mixed-signal components into a single chip. Nonetheless, chip designers still face the challenge of reducing the number of gates and imple-
