A 9GHz 65nm Intel Pentium 4 Processor Integer Execution Core

Abstract

In a 4th-generation 65nm Intel Pentiumreg4 processor, the previously low voltage swing, 2times microprocessor frequency, AGU and ALUs are replaced with domino-logic-based architectures optimized for low latency, 2times frequency, and lower power. These redesigned AGU/ALUs reduce normalized dynamic power by 50% over the previous generation, and together with the similarly optimized integer register file, enable a 9GHz 64b integer execution core at 1.3V and 70degC
