XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture version 5 instruction set.

XScale comprises several distinct families: XScale uses a seven-stage integer and an eight-stage memory super- pipelined microarchitecture. It is the successor to the Intel StrongARM line of microprocessors and microcontrollerswhich Intel acquired from DEC ‘s Digital Semiconductor division as part of a settlement of a lawsuit between the two companies.

The XScale core is used in a number of microcontroller families manufactured by Intel and Marvell:. There are also standalone processors: There was a choice of three clock speeds: It came out in February The PXA26x family was released in March This revision is a huge update to the XScale family of processors. The PXA is clocked in four different speeds: The PXA27x family was released in April They demonstrated it showing its capability to play back high definition encoded video on a PDA screen.

The new processor was shown clocked at 1. An announced successor to the G graphics processor, code named Stanwood, has since been canceled. For extra graphics capabilities, Intel recommends third-party chips like the Nvidia GoForce chip family. 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. There are ten different IOP processors currently available: The processors also differ in PCI bus type, PCI bus speed, memory type, maximum memory allowable, and the number of processor cores.

In IXP4XX devices the XScale core is used as both a control and data plane processor, providing both system control and data processing.

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.

The move was intended to permit Intel to focus its resources on its core x86 and server businesses. 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.

The acquisition was completed on November 9, Intel was expected to continue manufacturing XScale processors until Marvell secures other manufacturing facilities, and would continue manufacturing and selling the IXP and IOP processors, as they were not part of the deal.
