Abstract :
The power delivery system of a recent IA32 microprocessor is described. The microprocessor takes advantage of voltage positioning and selects its own operating voltage dynamically to optimize performance while maintaining reliability. This capability is used by the processor to change its operating voltage and frequency during normal operation.
