3. 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

4. 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.

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

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

7. 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
