Microprocessor is an IC which has only the CPU inside them i.e. The Microprocessor helps in performing the commands of computer processing. Microcontrollers are embedded devices, typically being optimized for the specific tasks they are designed for. Microcontroller. The lecture also covers common circuit that is used in microprocessors and microcontrollers which is the adder circuit. Microcontrollers, meanwhile, are limited in power and functionality, but can perform simple functions independently. Microprocessor is designed to be general purpose. For serial communication operations, FPGA’s are no so useful as compare to microprocessors. A microprocessor and a microcontroller are both essentially processors that are designed to run computers. Both microprocessor and microcontroller are often used in synonymous with each other because of the fact that they share common features and they are specifically designed for real time applications. What is a Microprocessor. Micro Controller has a processor along with internal memory and I/O components. The microcontrollers are cost-effective than microprocessors. It is not efficient. It performs Arithmetic Logical Unit (ALU) operations and communicates with the other devices connected with it. However, a microcontroller cannot be used in place of microprocessor and using a microprocessor is not advised in place of a microcontroller as it makes the application quite costly. A microprocessor cannot be used stand alone. A microcontroller sometimes uses abbreviated uC, µC, or MCU, is fundamentally a specialized variety of microprocessor that is intended to be self-satisfactory and lucrative. What are the basic units of a microprocessor ? All peripherals need to to connected separately. The microprocessor has one or two types of bit handling instruction. The microprocessor only comes with an internal controlling unit and all the memory and I/O components have to be externally installed. Microprocessor is solely used in personal computers, Microcontroller, on the other hand, is mainly used in cleaning machine like MP3 players. 2.
