There are also standalone processors: In IXP4XX devices the XScale core is used as both a control and data plane processor, providing both system control and data processing. Retrieved November 12, The move was intended to permit Intel to focus its resources on its core x86 and server businesses.

XScale uses a seven-stage integer and an eight-stage memory super- pax255 microarchitecture.

It came out in February The XScale core is used in a number of microcontroller families manufactured by Intel and Marvell:. Archived from the original on Marvell holds a full architecture license for ARM, allowing it to design chips to implement the ARM instruction set, not just license a processor core.

Archived from the original on April 16, There was a choice of three clock speeds: Articles with Dutch-language external links. The new processor was shown clocked at 1.

XScale – Wikipedia

The PXA is clocked in four different speeds: XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture version 5 instruction set.

Archived from the original on June 3, The task of the XScale in the IXP2XXX devices is typically to provide control plane functionality only, with data processing performed by the microenginesexamples of such control plane tasks include routing table updates, microengine control, memory management.

Views Read Edit View history. The PXA26x family was released in March Archived from the original on November 25, This page was last edited on 26 Septemberat Retrieved from ” https: Archived from the original on July 17, Discontinued BCD oriented 4-bit XScale comprises several distinct families: The PXA16x delivers strong performance at a mass market price point for cost sensitive consumer and embedded markets such as digital picture frames, E Readers, multifunction printer user interface UI displays, interactive VoIP phones, IP surveillance cameras, and home control gadgets.


It is also designed for low power consumption, using 2.

The PXA27x family was released in April For extra graphics capabilities, Intel recommends third-party chips like the Nvidia GoForce chip family. Intel was expected to continue manufacturing XScale processors until Marvell secures other manufacturing facilities, and would continue manufacturing and selling the IXP and Inteel processors, as they were not part of the deal.
