The AVR CPU combines a rich instruction set with 32 general purpose working registers. All the 32
registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers
to be accessed in one 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.
