Intel XScale PXA270
The LinuxLink software distribution model enables the usage of the Intel PXA270 LinuxLink for development targeting all designs based on PXA270 processor. The Intel® PXA270 processor is designed to meet the growing demands of a new generation of leading-edge embedded products.
Processor derivatives enabled:
The Intel PXA270 LinuxLink can also be used as a starting point for Linux development for designs based on any of the processors from the PXA27x family.
Reference boards/OEM boards enabled:
The Intel PXA270 LinuxLink can also be used as a starting point for Linux development for designs derived from:
Notes:
Complete peripheral support for PXA270 derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
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 to provide industry-leading MIPs/mW performance. 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.
