XScale is Intel's implementation of the 5th generation of the ARM architecture. XScale is a RISC microprocessor.
It is the successor to the Intel StrongARM microprocessors and microcontrollers, which Intel acquired from DEC's Digital Semiconductor division as the side-effect of a lawsuit between the two companies. Intel used the StrongARM to replace their ailing line of outdated RISC processors, the i860 and i960.
