Due to the large number of bits needed to encode the three registers of a 3-operand instruction, RISC processors using 16-bit instructions are invariably 2-operand machines, such as the Atmel AVR, the TI MSP430, and some versions of the ARM Thumb.

RISC processors using 32-bit instructions are usually 3-operand machines, such as processors implementing the Power Architecture, the SPARC architecture, the MIPS architecture, the ARM architecture, and the AVR32 architecture.

ARM processors accounted for approximately 90 % of all embedded 32-bit RISC processors and were used extensively in consumer electronics, including personal digital assistants ( PDAs ), tablets, mobile phones, digital media and music players, hand-held game consoles, calculators and computer peripherals such as hard drives and routers.

Most companies developing software with VRTX use ARM, MIPS, PowerPC or other RISC microprocessors.

MIPS, PA-RISC, ETRAX CRIS, SuperH, and SPARC are RISC architectures that each have a single branch delay slot ; PowerPC, ARM, and the more recently designed Alpha do not have any.

Despite being initially written for a single computer architecture, Open64 has proven that it can generate efficient code for CISC, RISC, and VLIW architectures, including MIPS, x86, IA-64, ARM, and others.

There are many differences in the core architecture between Blackfin / MSA and XScale / ARM or SHARC, but the combination provides improvements in performance, programmability and power consumption over traditional DSP or RISC architecture designs.

CORE Immolator, a level 1 defense tower that was supposed to be the CORE's response to the ARM Energy Machine Gun or EMG.

However, ARM have chosen to remain quiet on the exact execution environment details ; the documentation provided with Sun's HotSpot Java Virtual Machine goes as far as to state: For the avoidance of doubt, distribution of products containing software code to exercise the BXJ instruction and enable the use of the ARM Jazelle architecture extension without agreement from ARM is expressly forbidden ..

In 1992 Acorn once more won the Queen's Award for Technology for the ARM.

In the late 1980s Apple Computer and VLSI Technology started working with Acorn on newer versions of the ARM core.

In 1994, Acorn used the ARM 610 as the main central processing unit ( CPU ) in their Risc PC computers.

Acorn had originally expected ARM CPUs to progress from the 30 MHz ARM6 to the 40 MHz ARM7, and then onto the ARM8 cores, which at the time were clocked at around 50-80 MHz.

The Acorn Archimedes was Acorn Computers ' first general purpose home computer to be based on their own ARM architecture.

Its design was heavily influenced by work on the Modula-2 + language in use at SRC and at the Acorn Computers Research Center ( ARC, later ORC when Olivetti bought out Acorn ) at the time, which was the language in which the operating system for the DEC Firefly multiprocessor VAX workstation was written and in which the Acorn Compiler for Acorn Modula-2 Extended Language ( CAMEL ) at ARC for the ARX operating system project of ARM based Acorn Archimedes range of computers were written.

The ARM is the police force of the United Nations.

ARM originated as an acronym for " Amalgamation of Regional Militia ", though this is not a term in current usage by the time of the Known Space novels.

An agent of the ARM, Gil Hamilton, is the protagonist of Niven's sci-fi detective stories, a series-within-a-series gathered in the collection Flatlander ( Confusingly, " Flatlander " is also the name of an unrelated Known Space story.

* most processors ( including those of the Intel / AMD x86-32 / x86-64 family, the Motorola 68000 family, the AIM PowerPC family, the ARM family, and the Sun SPARC family ) set the signaled / quiet bit to non-zero if the NaN is quiet, and to zero if the NaN is signaling.

Darwin is now only available as source code, except for the ARM variant, which has not been released in any form separately from iOS.

Some of Acorn's former subsidiaries live on today — notably ARM Holdings, which is globally dominant in the mobile phone and PDA microprocessor market.

A slave interface is similar to programmed I / O through which the software ( running on embedded CPU, e. g. ARM ) can write / read I / O registers or ( less commonly ) local memory blocks inside the device.

This modification is widespread in modern processors such as the ARM architecture and X86 processors.

The ARM architecture is the most widely used 32-bit instruction set architecture in numbers produced.

The ARM architecture is licensable.

Because PE is used on Windows CE, it continues to support several variants of the MIPS, ARM ( including Thumb ), and SuperH ISAs.
