RISC (reduced instruction set Professional Website Design computer) is a microprocessor that is designed to perform a smaller number of types of computer instructions so that it can operate at a higher speed (perform more millions of instructions per second, or MIPS). Since each instruction type that a computer must perform requires additional transistors and circuitry, a larger list or set of computer instructions tends to make the microprocessor more complicated and slower in operation.

The RISC concept has led to a more thoughtful design of the microprocessor. Among design considerations are how well an instruction can be mapped to the clock speed of the microprocessor (ideally, an instruction can be performed in one clock cycle); how "simple" an architecture is required; and how much work can be done by the microchip itself without resorting to software help.

Besides performance improvement, some advantages of RISC and related design improvements are: A new microprocessor can be developed and tested more quickly if one of its aims is to be less complicated. Operating system and application programmers who use the microprocessor's instructions will find it easier to develop code with a smaller instruction set. The simplicity of RISC allows more freedom to choose how to use the space on a microprocessor. Higher-level language compilers produce more efficient code than formerly because they have always tended to use the smaller set of instructions to be found in a RISC computer.

Heh, I see what you did there. Nice try.

nice post.
personally the only assembly I have programmed in is hcs12.
you should look at my thread on the fetch executre cycle and tell me what you think, great to finally have foudn a forum with people who know what an architecture is.
