The company is best known for its processors, although it also designs, licenses and sells software development tools underdesigns, licenses and sells software development tools under the RealViewand KEIL brands, systems and platforms, system-on-a-chip infrastructure and software. ARM do not make ICs !!! ARMgrant license of core to different silicon vendors likegATMEL, NXP, Cirrus logic etc These companies make ICsp Examples are: LPC2148 from NXP, AT91RM9200 from ARM processors are used ARM processors can be used in any domain MainlyARMprocessors are used in Handheld devices Mainly ARMprocessors are used in Handheld devices, Robotics, Automation, Consumer Electronics.
