A 450 MHz IA32 P6 family microprocessor
Joseph Schutz, Robert Milo Wallace · 2002
A 1.4 V to 2.2 V 450 MHz CMOS 1.5 M transistor microprocessor in 131 mm/sup 2/ makes use of a five-layer-metal 0.25 /spl mu/m process technology. This is the third generation implementation of this microprocessor. This microprocessor implements the full Intel instruction set, including MMX(TM) technology instruction set extensions. This implementation adds new support for back side bus caches that transfer data at the core clock rate in 1 MB and 2 MB implementations to support 4-way servers.
