It is believed that the 8-bit AVR architecture and first AVR microcontroller was conceived and designed by two students at the Norwegian Institute of Technology.

The ELF file format is also used with the Atmel AVR ( 8-bit ), AVR32 and with Texas Instruments MSP430 microcontroller architectures.

Most notably this technique is used by Atmel AVR microcontrollers, and by others as well.

This technique is used in some microcontrollers, including the Atmel AVR.

The AVR is a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996.

Atmel says that the name AVR is not an acronym and does not stand for anything in particular.

However, it is commonly accepted that AVR stands for Alf ( Egil Bogen ) and Vegard ( Wollan )' s Risc processor.

The AVR is a modified Harvard architecture machine where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions.

The instruction set is similar to other RISC cores, but is not compatible with the original AVR or any of the various ARM cores.

There is no provision for off-chip program memory ; all code executed by the AVR core must reside in the on-chip flash.

In most variants of the AVR architecture, this internal EEPROM memory is not mapped into the MCU's addressable memory space.

GCC has included AVR support for quite some time, and that support is widely used.

* pAVR, written in VHDL, is aimed at creating the fastest and maximally featured AVR processor, by implementing techniques not found in the original AVR processor such as deeper pipelining.

* The SwinSID is hardware emulation of SID on the Atmel AVR processor and real SID player using Atmel AVR processor.

* ERIKA Enterprise ( ERIKA Enterprise, external link ) is an implementation of the OSEK OS ( BCC1, BCC2, ECC1, ECC2 ), OIL, ORTI specifications, provided with an Eclipse plugin and support for Microchip dsPIC, PIC32, AVR, Nios II, ARM7, S12XS, Tricore1, Mico32, PPC z7, esi-RISC, MSP430.

The concept is based on the AVR reactor and THTR in Germany, but modified to drive a Brayton closed-cycle gas turbine turbine.

Many computers ( such as x86 and AVR ) have one special-purpose register called the stack pointer which is implicitly incremented or decremented when pushing or popping data from the stack, and the source or destination effective address is ( implicitly ) the address stored in that stack pointer.

The Avon Valley Railway ( AVR ) is a three-mile-long heritage railway based at Bitton station in South Gloucestershire, England, not far from Bristol and is run by a local group: The Avon Valley Railway Company Ltd.

Unlike Peach Bottom, Dragon, AVR, HTTR, and HTR-10, all of which represent successful tests proving the principle of the HTGR technology, Fort St. Vrain was arguably doomed by the engineering mistake to use a first of a kind engineered, high-complexity steam turbine helium circulator with multiple fluid bearings instead of a simple, commercial off the shelf, KISS principle, low-complexity electric motor-based helium circulator, such as the electrical coolant circulators successfully used for decades in the UK's AGCR, which have stood and do stand the test of time in a similar, yet far more chemically hostile environment than that of a helium-cooled reactor core.

The New York Life Insurance Company ( NYLIC ) is one of the largest mutual life-insurance companies in the United States, and one of the largest life insurers in the world, with about $ 287 billion in total assets under management, and more than $ 15 billion in surplus and AVR.

The polarity of the < span style =" text-decoration: overline "> RESET </ span > line was opposite ( 8051's having an active-high RESET, while the AVR has an active-low < span style =" text-decoration: overline "> RESET </ span >) but other than that, the pinout was identical.

While considerably less powerful than the newer AT90 series of AVR RISC microcontrollers, new product development has continued with the AT89 series for the aforementioned advantages.

In most variants of the AVR architecture, the working registers are mapped in as the first 32 memory addresses ( 0000 < sub > 16 </ sub >– 001F < sub > 16 </ sub >) followed by the 64 I / O registers ( 0020 < sub > 16 </ sub >– 005F < sub > 16 </ sub >).

Three open-source keyer / keyset designs are available: The pickey a ps / 2 device based on the PIC microcontroller, the spiffchorder a USB device based on the Atmel AVR family of microcontrollers, and the GKOS keypad driver for Linux as well as the Gkos library for the Atmel / Arduino open source board.

* Atmel AVR family microcontrollers

The AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time.

Almost all AVR microcontrollers have internal EEPROM for semi-permanent data storage.

* Atmel AVR, a family of microcontrollers

Its products include microcontrollers ( including 8051 derivatives, AT91SAM and AT91CAP ARM-based micros, and its own Atmel AVR and AVR32 architectures ), radio frequency ( RF ) devices, EEPROM and flash memory devices ( including DataFlash-based memory ), and a number of application-specific products.

Today, QRG-based capacitive touch solutions using AVR microcontrollers form a large part of Atmel's product marketing efforts.

* Atmel AVR, family of 8-bit microcontrollers

However, in recent years, the ability to receive as well as send using cheap microcontrollers ( such as the Atmel AVR or the Motorola 68HC08 families ) have been demonstrated.

In Contiki 2. 6, platforms with the TI MSP430 and Atmel AVR microcontrollers can be emulated.

Released on December 26, 2008, the XGS AVR 8-Bit and XGS PIC 16-Bit development systems are embedded system development kits, meant to be very competitive entry / midrange development kits for their respective microcontrollers.

The AVR Butterfly comes preloaded with software that demonstrates many of the capabilities of the AVR microcontrollers.

A long but still not exhaustive list of common architectures are: 65816, 65C02, 68HC08, 68HC11, 68k, 78K0R / 78K0, 8051, ARM, AVR, AVR32, Blackfin, C167, Coldfire, COP8, Cortus APS3, eZ8, eZ80, FR-V, H8, HT48, M16C, M32C, MIPS, MSP430, PIC, PowerPC, R8C, RL78, SHARC, SPARC, ST6, SuperH, TLCS-47, TLCS-870, TLCS-900, TriCore, V850, x86, XE8000, Z80, AsAP and others.

Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus.

Examples include, the AVR by Atmel Corp, the PIC by Microchip Technology, Inc. and the ARM Cortex-M3 processor ( not all ARM chips have Harvard architecture ).

* The Atmel AVR and the PIC microcontroller each have a 2-stage pipeline.

Lamothe's latest next generation gaming products are the XGS AVR 8-Bit and XGS PIC 16-Bit, these systems are designed to be used as AVR / PIC development kits targeting engineers, hobbyists, and students.
