Desiping Low-Power/High-Performance Handheld Systems

摘要

Selecting a microprocessor for PDAs, PICs, and HPCs involves careful evaluation in a three-dimensional space. HPCs greatly resemble laptops, so they need to be expandable, have a broad base of ISVs targeting their customers, and have a standard operating system and GUI. Additionally, product differentiation depends on CPU speed, "user-perceived" performance, amount of memory, and cost. Finally, increasing density levels achieved by current CMOS processes allow the implementation of systems-on-silicon geared to optimizing performance, with minimum cost and power consumption.
