PXA270 processor
The ZEUS board is based on a PXA270 processor. The PXA270 processor is an
integrated system-on-a-chip microprocessor for high performance, low power portable
handheld and handset devices. It incorporates the Intel XScale technology with on-the-
fly voltage and frequency scaling and sophisticated power management.
The PXA270 processor complies with the ARM Architecture V5TE instruction set
(excluding floating point instructions) and follows the ARM programmer’s model. The
PXA270 processor also supports Intel Wireless MMX integer instructions in
applications such as those that accelerate audio and video processing.
The features of the PXA270 processor include:
• Intel XScale core.
• Power management.
• Internal memory - 256KB of on-chip RAM.
• Interrupt controller.
• Operating-system timers.
