The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage.
NanoVM is an open-source implementation of the Java virtual machine. The NanoVM was initially developed to run on the Atmel AVR ATmega8 used in the Asuro Robot. It was ported to run on the C't-Bot and the Nibo-robot and can easily be ported to other AVR-based systems.
The AVR Dragon provides in-system serial programming, high-voltage serial programming and parallel programming, as well as JTAG or debugWIRE emulation for parts with 32 KB of program memory or less. ATMEL changed the debugging feature of AVR Dragon with the latest firmware of AVR Studio 4 - AVR Studio 5 and now it supports devices over 32 KB of ...
For example, LPM (Load Program Memory) and SPM (Store Program Memory) instructions in the Atmel AVR implement such a modification. Similar solutions are found in other microcontrollers such as the PIC and Z8Encore!, many families of digital signal processors such as the TI C55x cores, and more. Because instruction execution is still restricted ...
In 2007, Atmel launched the second AVR32: The AVR32 UC3 core. This is designed for microcontrollers, using on-chip flash memory for program storage and running without an MMU (memory management unit). The AVR32 UC3 core uses a three-stage pipelined Harvard architecture specially designed to optimize instruction fetches from on-chip flash memory ...
Examples include the PIC by Microchip Technology, Inc. and the AVR by Atmel Corp (now part of Microchip Technology). Even in these cases, it is common to employ special instructions in order to access program memory as though it were data for read-only tables, or for reprogramming; those processors are modified Harvard architecture processors.
NanoVM – developed to run on the Atmel AVR ATmega8 used in the Asuro Robot, can be ported to other AVR-based systems. SableVM – first free software JVM to support JVMDI and JDWP. Makes use of GNU Classpath. LGPL. Version 1.13 released on March 30, 2007. Squawk virtual machine – a Java ME VM for embedded systems and small devices. Cross ...
TinyOS applications are written in the programming language nesC, a dialect of the C language optimized for the memory limits of sensor networks. [1] Its supplementary tools are mainly in the form of Java and shell script front-ends. Associated libraries and tools, such as the nesC compiler and Atmel AVR binutils toolchains, are mostly written ...
