CPU (Central processing Unit) The Arithmetic logic Unit (Arithmetic logic Unit) Control Unit Registers, three units that, in the early days of computer hardware development, were not in the chip of an integrated circuit.
Microprocessor Microprocessor: The three parts of the CPU and a small amount of peripheral circuits are integrated into a chip, but it is separated from the memory and peripheral interfaces. Microprocessors are divided into special and general purpose, special microprocessors such as DSP, GPU and so on.
