ARM architecture

ARM is a family of instruction set architectures for computer processors based on a reduced instruction set computing (RISC) architecture developed by British company ARM Holdings. ARM Holdings develops the instruction set and architecture for ARM-based products, but does not manufacture products. The company periodically releases updates to its cores. Current cores from ARM Holdings support a 32-bit address space and 32-bit arithmetic; the ARMv8-A architecture, announced in October 2011,[6] adds support for a 64-bit address space and 64-bit arithmetic. Instructions for ARM Holdings' cores have 32-bit-wide fixed-length instructions, but later versions of the architecture also support a variable-length instruction set that provides both 32-bit and 16-bit-wide instructions for improved code density. Some cores can also provide hardware execution of Java bytecodes. History[edit] Microprocessor-based system on a chip The ARM1 second processor for the BBC Micro Acorn RISC Machine: ARM2[edit]

GTA04 News: The codename GTA04 was picked up in 2010 by Golden Delicious Computers to develop a new motherboard for our open smartphone that follows the original idea and goals. There is a new project page: , which houses the wiki specific to the GTA04 project at Golden Delicious. GTA04A4 is a new motherboard, that replaces the one inside your Neo 1973 ( GTA01 ) or Neo Freerunner ( GTA02 ). ARM9 ARM9 is an ARM architecture 32-bit RISC CPU family. Overview[edit] There are two subfamilies, implementing different ARM architecture versions. Differences from ARM7 cores[edit] Key improvements over ARM7 cores, enabled by spending more transistors, include:[1]

Patented Dual-Crossbar Architecture for 32-bit ARM Microcontrollers Silicon Labs’ Precision32™ mixed-signal 32-bit microcontroller devices use a patented dual-crossbar architecture that allows designers to choose peripherals and pinout placement without worrying about pre-set limitations and pin conflicts — simplifying PCB routing, minimizing PCB layers and ultimately reducing design time and system cost. Here's what sets the 32-bit ARM microcontroller apart from the rest: Put Practically Any Peripheral On Any Pin Openmoko Beagle/Panda Hybrid - Beagleboard or Pandaboard with Openmoko Display News: We have been choosen by the PandaBoard Early Adopter Program and will receive a PandaBoard (OMAP4 / ARM Cortex A9) board soon. The Openmoko Beagle/Panda Hybrid is a PCB to connect an Openmoko Freerunner display (TD028TTEC1) through some connectors with a Beagle or Panda Board. It became the basis for a new Openmoko device and can therefore also be referenced as "GTA04A1".

ARM11 ARM11 is a family of ARM architecture 32-bit RISC microprocessor cores. Overview[edit] The ARM11 microarchitecture (announced 29 April 2002) introduced the ARMv6 architectural additions which had been announced in October 2001. These include SIMD media instructions, multiprocessor support and a new cache architecture. The implementation included a significantly improved instruction processing pipeline, compared to previous ARM9 or ARM10 families, and is used in smartphones from Apple, Nokia, and others. The initial ARM11 core (ARM1136) was released to licensees in October 2002. Math, Physics, and Engineering Applets Oscillations and Waves Acoustics Signal Processing
