Jim Keller, a veteran chip designer who started with Digital Equipment Corporation's Alpha processor before eventually starting P.A. Semi and subsequently joining Apple, has left the company to join Advanced Micro Devices (AMD). Keller will help lead the company in an effort to develop lower-power but more-efficient processors based on the ARM design, similar to the work he did with P.A. Semi and Apple. AMD recently noted it was now licensing ARM's processor designs.
