Overview
The Atmel AVR XMEGA is a family of low power, high performance, and
peripheral rich 8/16-bit microcontrollers based on the AVR enhanced
RISC architecture. By executing instructions in a single clock
cycle, the AVR XMEGA devices achieve CPU throughput approaching one
million instructions per second (MIPS) per megahertz, allowing the
system designer to optimize power consumption versus processing
speed.
The Atmel AVR CPU combines a rich instruction set with 32 general
purpose working registers. All 32 registers are directly connected
to the arithmetic logic unit (ALU), allowing two independent
registers to be accessed in a single instruction, executed in one
clock cycle. The resulting architecture is more code efficient
while achieving throughputs many times faster than conventional
single-accumulator or CISC based microcontrollers.
