Energy efficient multi-core microprocessors require on-chip voltage regulation according to researchers at IBM, Columbia University and Cornell. Look for on-chip voltage regulators in major microprocessors within three years. R.C.J.
The U.S. Department of Energy (DoE) has awarded Columbia University $2.8 million in Recovery Act economic stimulus funding to design power converters that efficiently regulate voltage for multi-core processors right on the chip, which could save U.S. data centers billions of kilowatts of energy yearly. IBM Research and Cornell University will also participate in the program to design on-chip voltage regulator modules using advanced magnetic induction methods.
