A complex instruction set computer ( CISC / ˈsɪsk /) is a computer architecture in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions.

O primeiro foi o CISC (Complex Instruction Set Computer), que teve muitas instruções diferentes. Na década de 1970, no entanto, a IBM fez uma pesquisa e descobriu que muitas instruções poderiam ser eliminadas. O resultado foi o RISC (Reduced Instruction Set Computer), uma arquitetura que utiliza um conjunto menor de instruções.
Em oposição, a arquitetura CISC ( Complex Instruction Set Computer, em português, "Computador com um conjunto complexo de instruções") possui um conjunto maior de instruções especializadas, algumas delas raramente usadas pelos programas. Muitos dos microprocessadores modernos são RISCs, por exemplo DEC Alpha, SPARC, MIPS, e PowerPC.
A complex instruction set computer ( acronym CISC pronounced sisk ), represents a CPU design method in which each instruction can execute several low-level operations, such as a load from memory, an arithmetic operation, and a memory store, all in a single instruction.
