A multimedia-enhanced x86 processor

Abstract

This x86 compatible CPU with multimedia functionality includes DRAM controller, accelerated graphics controller, and PCI bus interface. The integer pipeline and L1 cache of the CPU are enhanced to accelerate graphics and multimedia applications, and take advantage of the on-chip peripherals. Modules integrated onto the die are chosen because they are high-value functions with compelling performance or reduced complexity when integrated with the CPU. Graphics and video functions benefit from a tight integration with the CPU since partitioning of functions between hardware and software can differ from a traditional architecture without hurting performance.
