Atmel AVR is the industry standard for
the AVR architecture in microprocessors. The company picked up on the
new design from a couple of Norwegian students, and then chose to
advance and expand upon the capabilities of the new chip. The AVR was
the first of its kind to full use flash memory for the storage of
programs on the chip, and it eliminated the necessity for external
memory to be provided for its usage. Devices can still supply extra
memory through their buses to the AVR microprocessor, but it is a
little wonder when it comes to self-sufficiency. The Atmel AVR is low
powered and has good storage capacity,
through being able to integrate flash, EEPROM (Electrically Erasable
Programmable Read Only Memory) and SRAM (Static Random Access Memory).
The Atmel AVR is derived from the architecture of a Harvard 8bit RISC
single chip microprocessor. A RISC (reduced instruction set computer)
is a method in which instructions and commands can be executed at a
very fast rate, due to the simplicity of the language. By stripping
away anything unnecessary, and utilizing basic processes, the AVR is
able to operate at a high proficiency and reliability. This is
something that Atmel prides itself on. The Atmel AVR is able to handle
the demands of both 8 and 16 bit applications
that are put upon it.
It's efficiency works in a linear progression of company cycle, for it
automatically fetches the next one, which it is in the process of
executing another. The Atmel AVR is fully customizable through AVR
Studio, which links up a software user interface to get into the core
of the microprocessor. This allows the operator or designer to specify
their demands for the chip. The programs on the chip are small and
efficient with finely tuned instructions built for efficiency. With the
AVR Studio it is possible to write and reprogram the code for the
microprocessor instantly without having to disconnect the chip from any
circuitry. This, along with the readily available development kids, has
helped to push Atmel AVR's to the fore of micro controllers.
There are many varieties of the Atmel AVR microprocessor available,
covering a wide range of uses. The technology has come a long way from
its inception back in 1997, and there should be an AVR that will
exactly meet your demands. You can then build upon that architecture
with your own programming skills to achieve your goals and get the very
best out of the Atmel AVR. The structure is there along with
reliability, speed and efficiency.
