ARM Stands for Advanced RISC Machine….these are used as processors in almost all the Mobile Phones.

The main advantage of this processor over other processor is that it has a reduced instruction code, hence huge memory space is not required to store the programs….

Also that since these are designed using Hard wired control Logic i.e, these are designed using digital Circuits like logic Gates, Flip Flops, Decoders, Multiplexers etc.., hence the speed of Processing is very fast….

In 2005, about 98% of the more than one billion mobile phones sold each year used at least one ARM processor.[3] As of 2009, ARM processors account for approximately 90% of all embedded 32-bit RISC processors. ARM processors are used extensively in consumer electronics, including PDAs, mobile phones, digital media and music players, hand-held game consoles, calculators and computer peripherals such as hard drives and routers.

The ARM architecture is licensable. Companies that are current or former ARM licensees include Alcatel-Lucent, Apple Inc., Atmel, Broadcom, Cirrus Logic,Digital Equipment Corporation, Freescale, Intel (through DEC), LG, MarvellTechnologyGroup, Microsoft, NEC, Nuvoton, Nvidia, NXP (previouslyPhilips), Oki,ON Semiconductor, Qualcomm, Samsung, Sharp, STMicroelectronics, Symbios Logic, Texas Instruments, VLSI Technology, Yamaha and ZiiLABS.

ARM is the industry’s leading provider of 32-bit embedded microprocessors, offering a wide range of processors based on a common architecture that deliver high performance, industry leading power efficiency and reduced system cost. Combined with the broadest ecosystem in the industry with over 750 Partners delivering silicon, tools and software, the wide portfolio of more than 20 processors are able to meet every application challenge. With more than 20 billion processors already created and in excess of 10 million shipped every day, ARM truly is The Architecture for the Digital World®.

ARM Processors are used in….

Smart Phones( Motorola Droid, HTC desire, nokia N97 etc..,)

Smart books & Net books(Blackberry Playbook, Samsung Galaxy tablet)

Digital TV( High defnition Tv’s)

ARM is the world’s leading provider of physical semiconductor intellectual property (IP) for the design of complex System on Chip (SoC) integrated circuits. ARM is at the heart of the Smartphone in your pocket today with over three ARM powered chips in a typical device. ARM’s applications processors and Physical IP platforms, which consist of Logic IP, Embedded Memory IP and Interface IP that are optimized for a specific foundry process, combine to deliver the performance you need for the internet with great battery life that enables multi-day use.
