The ARM architecture (previously, the Advanced RISC Machine, and
prior to that Acorn RISC Machine) is a 32-bit RISC processor
architecture developed by ARM Limited that is widely used in a
number of embedded designs. Because of their power saving
features, ARM CPUs are dominant in the mobile electronics
market, where low power consumption is a critical design goal.
Today, the ARM family accounts for approximately 75% of all
embedded 32-bit RISC CPUs,making it one of the most prolific
32-bit architectures in the world. ARM CPUs are found in all
corners of consumer electronics, from portable devices (PDAs,
mobile phones, media players, handheld gaming units, and
calculators) to computer peripherals (hard drives, desktop
routers). Important branches in this family include Marvell's
XScale, the Texas Instruments OMAP series, Samsungs S3C24xx
series, and NXP's Bluestreak series. |CPU Core||Pipeline
