  RISC
RISC is a CPU design philosophy that followed from the discovery that many of the features that were included in traditional CPU designs for speed were being ignored by the programs that were running on them.
It was Sun's use of a RISC chip in their new machines that demonstrated that RISC's benefits were real, and their machines quickly outpaced the competition and essentially took over the entire workstation market.
As the original RISC architectures evolved, the ones that have survived (notably the PowerPC) have acquired a variety of additional instructions, some of which are for quite elaborate operations useful for graphics.

RISC follows the logical trend of moving away from vertically integrated institutions to one of horizontal segmentation and specialization.

 Ars Technica: RISC vs. CISC: the Post-RISC Era - Page 1 - (10/1999)   (Site not responding. Last check: 2007-10-13)
RISC was not a specific technology as much as it was a design strategy that developed in reaction to a particular school of thought in computer design.
It fails because RISC and CISC are not so much technologies as they are design strategies--approaches to achieving a specific set of goals that were defined in relation to a particular set of problems.
Back in 1981 when Patterson and Sequin first proposed the RISC I project (RISC I later became the foundation for Sun’s SPARC architecture), a million transistors on a single chip was a lot [1].

 Reduced instruction set computer - Wikipedia, the free encyclopedia
RISC was tailor-made to take advantage of these techniques, because the core logic of a RISC CPU was considerably simpler than in CISC designs.
UC Berkeley's RISC project started in 1980 under the direction of David Patterson, based on gaining performance through the use of pipelining and an aggressive use of registers known as register windows.
However, despite many successes, RISC has made few inroads into the desktop PC and commodity server markets, where Intel's x86 platform remains the dominant processor architecture (Intel is facing increased competition from AMD, but even AMD's processors implement the x86 platform, or a 64-bit superset known as x86-64).

 MacKiDo/Dojo/EPICisRISC
In RISC you use "Superscalar" to load lots of single instructions, and the processor executes them in parallel (at the same time) -- all decoding (reordering, etc.) is done by the chip.
Say you are loading 4 x RISC instructions at the same time, then you want to improve the processor.
RISC does the parallelism as well -- but the compiler doesn't have to optimize (specialize) the code (as much).

 MacKiDo/Hardware/WhatIsRISC
RISC is just a name we've given on a certain design philosophy (that came from a collection of techniques to make processors better.
RISC instructions have all instructions the same size -- and everything is aligned -- but not all data sizes and instructions need the same amount of data (or instruction complexity).
RISC started as all fixed size and perfectly aligned data -- but working with legacy data was near impossible (since it wasn't perfectly aligned) -- so they added in support for misaligned data.

 RISC vs. CISC
RISC processors only use simple instructions that can be executed within one clock cycle.
RISC does the opposite, reducing the cycles per instruction at the cost of the number of instructions per program.
Although RISC chips might surpass Intel's efforts in specific areas, the differences were not great enough to persuade buyers to change technologies.

One primary benefit of RISC processors is the high performance at low power consumption at a lower cost compared with typical Pentium-level x86 processors applied to embedded applications, especially mobile applications.
RISC is always designed for a specific application; it should be compact and proprietary.
By making the hardware simpler, RISC architecture puts a greater burden on the software, which means it might not be good for some applications because of this simple structure.

 RISC   (Site not responding. Last check: 2007-10-13)
RISC computers are more efficient because the microcode layer, and its associated overhead (read: performance loss) is eliminated.
RISC keeps the instruction size constant, where CISC instruction size, on the other hand, is greatly variable.
RISC retains only the instructions that can be overlapped and made to execute in one clock cycle or less.

 RISC - a Whatis.com definition
RISC (reduced instruction set 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).
John Cocke of IBM Research in Yorktown, New York, originated the RISC concept in 1974 by proving that about 20% of the instructions in a computer did 80% of the work.
The term itself (RISC) is credited to David Patterson, a teacher at the University of California in Berkeley.

 [No title]   (Site not responding. Last check: 2007-10-13)
RISC processors, first developed in the eighties, seem predestined to dominate the computer industry in the nineties and to relegate old microprocessor architectures into oblivion.
The main difference between RISC and CISC, is that the instruction set of the first kind of processors was explicitly designed to allow the sustained execution of instructions in one cycle as average.
RISC has also been called a "scalable architecture" because it is possible to go from one technology to another with practically the same design (from CMOS to ECL, for example).

 CISC Vs. RISC   (Site not responding. Last check: 2007-10-13)
The term 'RISC' (short for Reduced Instruction Set Computer) was later coined by David Patterson, a teacher at the University of California in Berkeley.
The RISC concept was used to simplify the design of the IBM PC/XT, and was later used in the IBM RISC System/6000 and Sun Microsystems' SPARC microprocessors.
As the world enters the 21st century the CISC Vs. RISC arguments have been swept aside by the recognition that neither terms are accurate in their description.

 The Ultimate RISC
In general, RISC machines are characterized by fixed format instructions and extensive use of pipelined execution, while CISC machines have variable length instructions and extensive use of microprogramming.
A minimal implementation of the ulitmate RISC architecture requires an instruction execution unit, a memory, input-output devices, and a bus to connect these.
The minimal ultimate RISC can only be proven to be suboptimal if a processor can be found that is better when measured along at least one axis of the design space while being no worse along any other axes.
