Overview What does ARM stand for? Who created it The RISC approach Difference from other CPUs Current uses New applications Raspberry Pi Future uses Final Remarks Resources Arm Architecture. Group 17: Amber Luu, Paul Lewis

ARM stands for Advanced RISC Machine Originally Acorn RISC Machine Reduced Instruction Set Computer Acorn- British computer company ARM architecture describes a family of computer processors designed in accordance with a RISC CPU design Arm Architecture. Group 17: Amber Luu, Paul Lewis

Who Created It? Developed by the advanced research and development team at Acorn Computers Was one of the leading names in British personal computer market At the time it was considered to be the British version of Apple Originally conceived for use in their personal computers.

Rethinking Their Approach Their original architecture worked great until IBM started building much more powerful computers. They tried many different designs but none were suitable for a graphics based user interface. After reading about the Berkeley RISC project, they decided that if a class of graduate students could create a competitive processor, they could too. Arm Architecture.

The RISC Approach The official Acorn RISC Machine project started in October 1983 The core ARM processor requires significantly fewer transistors than processors that would typically be found in a traditional computer. Benefits include: – – – Lower costs Less heat Less power usage Arm Architecture. Group 17: Amber Luu, Paul Lewis

Acorn No More The company was incorporated in 1990, the acronym was changed to stand for "Advanced RISC Machines. " Then, at the time of the IPO in 1998, the company name was changed to "ARM Holdings. " Arm Architecture. Group 17: Amber Luu, Paul Lewis

Difference From Other CPUs Marketing and Production – ARM itself doesn't make chips - it licenses the IP needed to make ARM-based processors. – This lets Samsung, Qualcomm, Nvidia and up to 15 other outfits to bring in their own tech and that of third parties to create a product tailored for an application. – Instead of AMD and Intel where they create a one-size-fits-all chip designed and manufactured by a single company.

Current Usage In 2011, ARM's customers reported 7. 9 billion ARM processors shipped, representing: 95% of smartphones 90% of hard disk drives 40% of digital televisions and set-top boxes 15% of microcontrollers 20% of mobile computers Arm Architecture. Group 17: Amber Luu, Paul Lewis

You Have Probably Used One Today Most notable current uses: Apple i. Pad / i. Phone Microsoft Surface ASUS Eee Transformer Nintendo DS Tom Architecture. Group 17: Amber Luu, Paul Lewis

What Does This Mean For You? Increased competition for leading chip manufacturers. With how easily they can be custom designed, there will be more and more options for people who want them as they become more powerful. Best example: Raspberry Pi Arm Architecture. Group 17: Amber Luu, Paul Lewis

Raspberry Pi Credit card sized computer Weighs 45 g Invented to encourage a new generation of young people to get into computing Plugs into TV or monitor 512 MB RAM, HDMI, SD, LAN, 2 USB, Audio, RCA Video, GPIO Runs Debian/Arch/etc. Cost $25 or $35 Arm Architecture. Group 17: Amber Luu, Paul Lewis

What Can You Do With It? Make a HTPC Can play 1080 p video Create a fully functional SNES emulator Mini webserver Arm Architecture. Group 17: Amber Luu, Paul Lewis

Growing Support Apple to dump Intel? Apple engineers are becoming confident that the ARM chip design they use for i. Phones/i. Pads will become powerful enough for PCs. Most major Linux distros support it. Google added ARM support to Chrome's Native Client. Arm Architecture. Group 17: Amber Luu, Paul Lewis

The Next Generation Cortex-A-50 series Energy-efficient 64 -bit processing technology. Will provide performance up to three times that of today's superphones without increasing power usage. Arm Architecture. Group 17: Amber Luu, Paul Lewis

Final Remarks Will it ever replace AMD or Intel? Emerging use in servers. The usefulness of the Raspberry Pi project. Arm Architecture. Group 17: Amber Luu, Paul Lewis
