The CISC architecture uses more complex instructions, where a single instruction can execute several operations, such as loading data from memory, performing an operation, and storing the result back to memory. This reduces the number of instructions per program but increases the complexity of each instruction. For example, here the ADD instruction might carry out the loading of data, the operation, and storing the result back to memory in a single instruction:
ADD 1000, 1001, 1010
This is known as a complex instruction.
Most modern desktop and laptop computers, including PCs and Intel Macs, use the CISC architecture found in Intel and AMD processors.
