Contents About ARM & History Backbone Technology- RISC ARM- Core & Extensions ARM Families & Applications Future Scope

What Is ARM? Advanced RISC Machine developed by ARM Ltd. 32-bit RISC-ISA Used in embedded systems and consumer electronics Dominant in mobile electronics market

History Acorn computers Ltd started making Acorn RISC Machine in 1983 Apple Computers and VLSI Technology Inc. joined in 1990 Advanced RISC Machine Ltd. Sells cores to licensees Key licensees: Alcatel, Atmel, Intel, IBM, Nintendo, Samsung, Sharp, Texas Instruments, VLSI Inc.

Backbone Technology-RISC Reduced Instruction Set Computer Reduced instruction size, increased instruction set Simple pipelining Load or store architecture Simple addressing modes

ARM-ISA CORE::: Load or store architecture 16 by 32 bit register file 32 bit fixed instruction width Single-cycle execution

Extensions TRUST ZONE JAZELLE DSP THUMB High code density 16-bit opcodes 40% usage 30% less space Thumb2, ThumbEE JAVA bytecodes Increase speed of games etc. Signal processing tasks DSP instruction set NEON Security extention 2 virtual processors

ARM Families ARM Families ARM processor range ARM7 ARM9 ARM9E ARM10E SecureCore Cortex family- market specific applications

ARM Processor system categories 1 Embedded real-time systems: storage, automotive, power train, industrial, networking 2 Application systems: Entertainment, imaging 3 Secure Applications: Smart cards, SIM cards, banking payments

Future Scope Palm-Pre and Apple I-phone currently use Cortex A8 Multi-core ARM processors by next year Next generation dual-core ARM processor is Cortex A9
