The AVR family
The AVR32 Microprocessor Architecture
AVR32
AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for cost-sensitive
embedded applications, with particular emphasis on low power consumption and high code den-
sity. In addition, the instruction set architecture has been tuned to allow for a variety of
microarchitectures, enabling the AVR32 to be implemented as low-, mid- or high-performance
processors. AVR32 extends the AVR family into the world of 32- and 64-bit applications.
The AVR family was launched by Atmel in 1996 and has had remarkable success in the 8-and
16-bit flash microcontroller market. AVR32 is complements the current AVR microcontrollers.
Through the AVR32 family, the AVR is extended into a new range of higher performance appli-
cations that is currently served by 32- and 64-bit processors
To truly exploit the power of a 32-bit architecture, the new AVR32 architecture is not binary com-
patible with earlier AVR architectures. In order to achieve high code density, the instruction
format is flexible providing both compact instructions with 16 bits length and extended 32-bit
instructions. While the instruction length is only 16 bits for most instructions, powerful 32-bit
instructions are implemented to further increase performance. Compact and extended instruc-
tions can be freely mixed in the instruction stream.
The AVR32 is a new innovative microprocessor architecture. It is a fully synchronous synthesis-
able RTL design with industry standard interfaces, ensuring easy integration into SoC designs
with legacy intellectual property (IP). Through a quantitative approach, a large set of industry
recognized benchmarks has been compiled and analyzed to achieve the best code density in its
class of microprocessor architectures. In addition to lowering the memory requirements, a com-
pact code size also contributes to the core’s low power characteristics. The processor supports
byte and half-word data types without penalty in code size and performance.
Memory load and store operations are provided for byte, half-word, word and double word data
with automatic sign- or zero extension of half-word and byte data. The C-compiler is closely
linked to the architecture and is able to exploit code optimization features, both for size and
speed.
In order to reduce code size to a minimum, some instructions have multiple addressing modes.
As an example, instructions with immediates often have a compact format with a smaller imme-
diate, and an extended format with a larger immediate. In this way, the compiler is able to use
the format giving the smallest code size.
Another feature of the instruction set is that frequently used instructions, like add, have a com-
pact format with two operands as well as an extended format with three operands. The larger
format increases performance, allowing an addition and a data move in the same instruction in a
single cycle.
Load and store instructions have several different formats in order to reduce code size and
speed up execution:
• Load/store to an address specified by a pointer register
• Load/store to an address specified by a pointer register with postincrement
