CISC - Complex Instruction Set Computer
Processors designed with full set of instructions to provide functions in the most efficient way.
CISC has the capacity to perform multi-step operations or addressing modes within one instruction set. It is the CPU design where one instruction works several low-level acts. For instance, memory storage, loading from memory, and an arithmetic operation.
Unlike RISC, CISC instructions can perform
complex tasks that take more than one cycle to execute. These can include
floating-point mathematical calculations and graphics-handling instructions. CISC
can be highly efficient in terms of the number of instructions per program, resulting
in lower demand for code storage and RAM compared to RISC. On the other hand, a
CISC processor must contain more transistors to handle the complexity of the
