Reduced Instruction Set Computing. Pronounced "risk." Unlike CISC, RISC reduces the number of instructions as much as possible. RISC chips are generally cheaper to develop and manufacture. Typically, a similar RISC processor can process operations up to 75% faster than a comparable CISC processor at the same clock speed. RISC computers originate from IBM research in the early 1970's. See CISC.
A computer architecture using a small set of instructions at the hardware level. RISC enables a complex processor to be built from very high-speed, simple components.

educed nstruction et omputing is one of the two main types of processor design in use today, the other being CISC. The fastest processors in the world today are all RISC designs. There are several popular RISC processors, including Alphas, ARMs, PA-RISCs, PowerPCs, and SPARCs.
processor a processor implementing the computer design philosophy of a relatively simple control unit design with a reduced number of instructions (selected to be simple), data and instructions formats, and addressing modes. The processor is pipelined. One of the particular features of a RISC processor is the restriction that all memory accesses should be by load and store intructions only (the so-called load/store architecture). All arithmetic logic operations in a RISC are register-to-register, meaning that both the sources and destinations of all operations are CPU registers. All this tends to reduce CPU-to-memory data traffic significantly, thus improving performance. In addition, RISC s usually have the following properties: most intructions execute within a single cycle, all instructions have the same size, the control unit is hardwired (to increase the speed of operations), and there is a CPU register file of considerable size.

reduced instruction set computer. A microprocessor designed to perform a smaller number of types of computer instructions. It can operate at a higher speed so it is therefore cheaper and faster than standard processors.
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.

hardware:(Reduced instruction set computing) - Processor architecture that runs much faster by relying on a reduced set of simplified instructions. The goal is that one CPU instruction can be performed every clock cycle. Although more instructions (therefore longer programs) are necessary to carry out complex processor tasks, RISC still is faster because the bulk of all computing is simple instructions. Apple's new PowerPCs are RISC processors, and it is the prospect of greatly increased speed (as well as lower cost) that drove the decision to change from the CISC Motorola 680x0 line.

Reduced instruction set computer. A computer processing architecture that requires fewer instructions to run applications, thus increasing processing speed.
(Reduced Instruction Set Computer) Used with advanced engineering workstations along with other computers. The RISC processor is designed to optimize a CPU's processing speed by using a smaller instruction set. That is, they use a smaller number of the basic machine instructions that a processor is capable of executing. This enables a RISC processor to reduce the time needed to execute program instructions. RISC processors have been widely used in the computational-intensive applications in engineering and the physical sciences. [Articles

Reduced Instruction Set Computer. Computer architecture using a very small set of instructions at the hardware level. The idea is to find the small set of instructions that are used most frequently, and then to design a chip that implements just these instructions, and executes them extremely quickly. More complex instructions are implemented in firmware and/or compiler s. IBM invented the RISC concept, first used it in the RT PC, and then in the RS/6000. It also licenses the technology to third parties, including Sun Microsystems, which makes the Sparc RISC chip. RISCs are also used as auxiliary ( channel, firmware) processors in the mainframe. There are good reasons to believe that the ultimate (literally) IBM architecture will be a parallel CEC using from one to thousands of RISC chips depending on how big a machine you want. Don’t believe that reduced means fewer – the RISC chip used in the RS/6000 has more instructions than the 370 had. See also VLIW.

Reduced Instruction Set Computer. An architecture that shifts the analytical process of a computational task from the execution or run time to the preparation or compile time. By using less hardware or logic, the system can operate at higher speeds. A processor architecture that cuts down on the number and complexity of instructions, on the theory that each one can be accessed and executed faster, and that less semiconductor circuitry is required to process them. The result is that for any given semiconductor technology, a more powerful microprocessor can be produced with RISC than with CISC (complex instruction set computer) architectures. However, the compilers role becomes critical, and the effective throughput of the system will heavily depend on them.
