StrongARM is a microprocessor on basis of arm architecture. The processor became common by Digital Equipment corporation (DEC) and Advanced RISC Machines Ltd. (ARM) develops. After Intel had bought large parts of DEC, they have later also the StrongARM of ARM licensed. In the meantime Intel developed its own processor core on basis of arm architecture, the XScale. That did not happen however completely voluntarily, because with the assumption of DEC by Intel many developers left, among other things the company the entire designer team of the StrongARM, which had already worked on the successor StrongARM2. For XScale architecture the team, which to Intel the i960 had worked before, were therefore used.

The StrongARM developed on suggestion of Apple, in order to be able to offer in Newton, one the first PDAs, better achievement with less current consumption. 1995 were the first version of the StrongARM SA-100 and ensured by its current savings mode in Newton 2100 for sensational Akkulaufzeiten. In addition the successor SA-1110 has an LCD Touchscreen CONTROLLER, PCMCIA support, IrDA, USB and DMA (direct memory access) CONTROLLER, which makes him an interesting system on A chip for PDAs.

(The statement that the StrongARM was developed quasi on behalf of Apple, in the preceding paragraph, appears at least doubtful. Like that Acorn, who was besides also inventor of the arm processor, was a processor map with StrongARM110 already starting from 1996 available for the Risc PC, a Desktop computer of the company. Newton the MessagePad 2000 was probably only offered against it starting from 1997.)

The StrongARM microprocessor is used frequently into PDAs like Newton, the pocket PC or the Sharp Zaurus SL 5500.

The StrongARM has a ARMv4 core and separate Caches for data and instructions, similarly as Motorola 68000er family.

Software support

Linux, NetBSD, OpenBSD, Windows CE, RISC OS and VxWorks support the StrongARM processor.
