Overview

The PXA320 processor is an integrated system-on-a-chip microprocessor for high-performance,
low-power portable handheld and handset devices. It incorporates the Intel XScale® micro
architecture with on-the-fly voltage and frequency scaling and sophisticated power management
to provide industry leading MIPS/mW performance across its wide range of operating frequencies.
The PXA320 processor complies with the ARM* Architecture V5TE instruction set (excluding
floating point instructions) and follows the ARM* programmer’s model. The PXA320 processor
Multimedia coprocessor provides enhanced Intel® Wireless MMX 2 instructions to accelerate
audio and video processing.
