complex instruction set computing. A processor that can recognize and execute well over 100 different assembly-language instructions. See also RISC.
processor a processor with a large quantity of instructions, some of which may be quite complicated, as well as a large quantity of different addressing modes, instruction and data formats, and other attributes. A CISC processor usually has a relatively complicated control unit. Most CISC processors are microprogrammed. [SILC99
Intel x86 chips are CISC chips because of the complexity of the instruction set. On the other side of the coin, you have RISC chips that use a reduced instruction set. RISC chips split big operations into lots of simple, tiny instructions that are processed very quickly. Some people argue that RISC chips have the edge. Several Intel competitors such as Cyrix and AMD use RISC chips with CISC converters to compete against Intel's chips.
(adj.) Complicated instruction set computer; a computer that provides many powerful but complicated instructions. This term is also applied to software designs that give users a large number of of complex basic operations. See also RISC.
Stands for "Complex Instruction Set Computing." This is a type of ...
(computer science) a kind of computer architecture that has a large number of instructions hard coded into the cpu chip
Design used by the CPU that supports a large number of instructions. 4.6 Cisco Certified Internetwork Expert (CCIE), 16.21, 16.22, 16.23 Cisco Certified Network Professional (CCNP), 16.22
(Complex Instruction Set Computing). A design approach that attempts to achieve performance gains with complex instruction and data types and hardware controlled memory management.
(Complex Instruction Set Computing) Older form of processor that uses large, complex instructions to manipulate data. At this time, only the Pentium- and Celeron-class processors use this technology. (See also: RISC)
(Complex Instruction Set Computer) Describes the architecture of a processor family. CISC processors generally feature variable-length instructions, multiple addressing formats, and contain only a small number of general-purpose registers. Intel's 80x86 family is the quintessential example of CISC. Contrast with RISC.

An abbreviation for omplex nstruction et omputer. A design philosophy for computers whereby the processor is designed to execute a relatively large number of different instructions, each taking a different amount of time to execute (depending on the complexity of the instruction). Contrast with RISC.
The term "CISC" (complex instruction set computer or computing) refers to computers designed with a full set of instruction that were intended to provide needed capabilities in the most efficient way. Later, it was discovered that, by reducing the full set to only the most frequently used instructions, the computer would get more work done in a shorter amount of time for most applications. Since this was called reduced instruction set computing (reduced instruction set computer), there was now a need to have something to call full set instruction computers thus, the term CISC.
Complex Instruction Set Computer. The opposite of RISC, a processor which supports a large number of often complex assembly instructions. The X86 architecture is a CISC architecture.
Complex Instruction Set Computers. A category of computer processors based around a set of fairly high-level, powerful instructions; cf. RISC.
An acronym for the Complex Instruction Set Computer. The central processing unit designed to support the direct execution of very complex operations in one (or very few) processor cycles
The standard processor for IBM compatible PC executing large instructions slowly. The other processor standard is the RISC processor.
hardware:(Complex Instruction Set Computer) - Processor architecture that is capable of handling lengthy, complex instructions (code) which often require more than one clock cycle to complete. Program file length is kept to a minimum; the trade-off is that this type of processing runs slower than comparable RISC (reduced) processing. Motorola's 680x0 chips, and Intel's -86 chips are popular CISC devices. Until the introduction of the PowerPC, all desktop computers used CISC architecture.
Pronounced sisk, and stands for Complex Instruction Set Computer. Most personal computers use a CISC architecture, in which the CPU supports as many as two hundred instructions. An alternative architecture used by many workstations and also some personal computers, is RISC (reduced instruction set computer), which supports fewer instructions.
complex instruction set computer. A central processing unit that can recognize as many as 100 or more instructions and carry out most computations directly.
(Complex Instruction Set Computing) -A chip architecture that uses a robust complement of instructions. Although a CISC-based computer instruction can perform a lot of work, the instruction can require many CPU cycles to do it. (See RISC).
Complex Instruction Set Computer. Intel® Pentium® processors are built using CISC architecture. CISC instructions are generally longer and more complex. Not as many can be completed per second, but each instruction does more work in comparison to the more streamlined RISC instructions.
Complex Instruction Set Computer. A computer processor with a rich and varied instruction set. This enables it to be suitable for supporting a variety of operating systems and compilers and to have many different uses.
Complex Instruction Set Computer (CISC ) is a computer architecture that has a large number of instructions hard coded into the CPU chip.
Complex instruction set computing. Includes numerous variable-length machine instructions that are more complex than RISC. See also RISC and VLIW.
(Complex Instruction Set Computer) A type of processor that recognises and processes a large number of complex and powerful instructions without the need for additional software.
Complex Instruction Set Computer. A computer in which individual instructions may perform many operations and take many cycles to execute , in contrast with reduced instruction set computer. Examples include IBM System/370, Digital Equipment Corp. VAX, Motorola 68020 and Intel 80386.
Complex Instruction Set Computer. A microprocessor which implements users instructions at an assembly language level. These instructions are made up of multiple "sub-instructions" known as microcode that actually drive the hardware state machines of the microprocessor. Typical complex instructions require multiple clock cycles for execution as the microcode is processed.
Complex Instruction Set Computing. A CPU architecture in which a large number of instructions are hard coded into the chip. Most older CPUs are CISC chips, like the Motorola 680x0, the Intel 80x86, etc. The Pentium chips have some RISC like features, but are still basically CISC chips. Contrast with RISC.
