CISC
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.

CISC
Complex Instruction Set Computer (CISC)
A CISC microprocessor design provides many instructions in order to ease programming. Of course, the many similar yet different instructions complicates instruction decoding by the microprocessor, so you pay the semplification in program writing with lower performances and higher costs.Complex Instruction Set Computer.
