A microprocessor is an integrated circuit (IC) which incorporates core functions of a computer’s central processing unit (CPU). It is a programmable multipurpose silicon chip, clock driven, register based, accepts binary data as input and provides output after processing it as per the instructions stored in the memory.
A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC). The integration of a whole CPU onto a single or a few integrated circuits greatly reduced the cost of processing power. Integrated circuit processors are produced in large numbers by highly automated metal-oxide-semiconductor (MOS) fabrication processes, resulting in a low unit price than cpu.
A microprocessor is a general-purpose entity. Several specialized processing devices have followed:
- A digital signal processor (DSP) is specialized for signal processing.
- Graphics processing units (GPUs) are processors designed primarily for realtime rendering of images.
- Other specialized units exist for video processing and machine vision. (See: Hardware acceleration.)
- Microcontrollers integrate a microprocessor with peripheral devices in embedded systems.
- Systems on chip (SoCs) often integrate one or more microprocessor or microcontroller cores.
