<processor> (RISC) A processor whose design is based on the
rapid execution of a sequence of simple instructions rather
than on the provision of a large variety of complex
instructions (as in a Complex Instruction Set Computer).
Features which are generally found in RISC designs are uniform
instruction encoding (e.g. the op-code is always in the same
bit positions in each instruction which is always one word
long), which allows faster decoding; a homogenous {register
set}, allowing any register to be used in any context and
simplifying compiler design; and simple addressing modes
with more complex modes replaced by sequences of simple
arithmetic instructions.
Examples of (more or less) RISC processors are the {Berkeley
RISC}, HP-PA, Clipper, i960, AMD 29000, MIPS R2000
and DEC Alpha. IBM's first RISC computer was the RT/PC
(IBM 801), they now produce the RISC-based {RISC
System/6000} and SP/2 lines.
Despite Apple Computer's bogus claims for their
PowerPC-based Macintoshes, the first RISC processor used
in a personal computer was the Advanced RISC Machine (ARM)
used in the Acorn Archimedes.

In computer engineering, a reduced instruction set computer (RISC) is a computer designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more code) in order to accomplish a task because the individual instructions are written in simpler code.
Atmel AVR instruction set
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.
