The Medfield Smartphone: Intel Architecture in a Handheld Form Factor

Medfield is the code name for the first Intel smartphone platform that delivers an Intel Architecture (IA) processor into a handheld form factor. Medfield is built around the Intel Atom Z2480 Processor. The platform uses the Intel Hi-K 32 nm process technology to deliver a compelling end-user experience within the low power constraints demanded by the form factor. This article covers platform and system-on-a-chip (SoC) design constraints ranging from board layout to chip packaging, silicon design to software architecture. The authors emphasize the hardware and software power-management techniques that allowed the product to meet smartphone compatible battery life targets.
