StrongARM is a microprocessor based on the ARM architecture . The processor was jointly developed by Digital Equipment Corporation (DEC) and ARM Limited . After Intel had bought the chip design part from DEC, Intel later also licensed ARM's StrongARM. In the following, Intel developed its own processor core XScale based on the ARM architecture.

In 1995 the first version of the StrongARM SA-100 was ready and, thanks to its power-saving mode, the Newton 2100 allowed comparatively longer battery life. These features of the successor SA-1110 via an LCD - Interface , an MCP-Audio / touchscreen interface, PCMCIA support, IrDA , USB and DMA controllers. The StrongARM microprocessor was often used in the first PDAs such as the Newton , Pocket PCs or the Sharp Zaurus SL 5500.

The StrongARM has an ARMv4 core and separate caches for data and instructions, similar to the Motorola 68000 family.

The StrongARM was also used in the experimental amateur radio satellite AMSAT OSCAR 40 .

Software support

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