Study Notes
Microprocessor and Microcontroller
- A microprocessor is a controlling unit of a microcomputer wrapped inside a small chip.
- It performs Arithmetic Logical Unit (ALU) operations and communicates with other devices connected to it.
- A microprocessor is a single Integrated Circuit (IC) that combines several functions, including a computer's central processing unit (CPU).
Microcomputer
- A microcomputer is an electronic device with a microprocessor as its central processing unit (CPU).
- It was formerly a commonly used term for personal computers, particularly any of a class of small digital computers whose CPU is contained on a single integrated semiconductor chip.
Microcontroller
- A microcontroller is a chip optimized to control electronic devices.
- It is stored in a single integrated circuit dedicated to performing a particular task and executing one specific application.
- It contains memory, processor, and programmable I/O.
- Microcontrollers are widely used in automatically controlled electronic devices.
Embedded System
- An embedded system is a microcontroller or microprocessor-based system designed to perform a specific task.
- It can be an independent system or part of a larger system.
- Examples of embedded systems include fire alarms, which sense only smoke.
Difference between Microprocessor and Microcontroller
- Microprocessor only has a CPU in the chip, whereas Microcontroller has RAM, ROM, and other peripherals along with the CPU or processor.
- Microprocessor and Microcontroller have different applications, advantages, and disadvantages.
- They can be differentiated in terms of applications, structure, internal parameters, power consumption, and cost.
Structure of Microprocessor and Microcontroller
- Microprocessor is used in very intensive processes and only contains a CPU.
- External parts like RAM, ROM, I/O ports, timers, and serial interfaces are connected to the microprocessor chip.
- Microcontroller has a fixed structure, with all parts integrated with the CPU in a single chip, making it smaller compared to the microprocessor.
Internal Parameters of Microprocessor and Microcontroller
- Microprocessor and Microcontroller differ in internal parameters like clock speed, memory (RAM and ROM), peripheral interface, etc.
- Microprocessor has higher clock speeds (1 GHz to 4 GHz) compared to Microcontroller (1 MHz to 300 MHz).
- Microprocessor has larger memory requirements (512 MB to 32 GB RAM and 128 GB to 2 TB ROM) compared to Microcontroller (2 KB to 256 KB RAM and 32 KB to 2 MB ROM).
Applications of Microprocessor and Microcontroller
- Microprocessor is used in applications where the task is not predefined and is assigned by the user (e.g., computers, mobiles, video games, TVs).
- Microcontroller is designed for a specific task and is used in electronic appliances like washing machines, microwave ovens, and timers.
- Microprocessor is used where intensive processing is required, whereas Microcontroller is used for specific tasks with fixed processing.
