A Complex Instruction Set Computer is a processor designed with complete computer instruction set to provide maximum capabilities in the most efficient way. These were developed to support high-level languages instructions like looping, procedure calls and return and also allowing complex addressing modes for array and data structures in single instructions. These processors can execute several low-level operations like arithmetic operations, fetch from memory, store memory etc. and various multi-step instructions and complex addressing modes in fewer instructions. Examples include the Intel Pentium and Motorola 680×0 families.
