The Hardware refers to the components or devices used to form computing machine in which the software can be run and tested. The Software is a set of instructions or commands needed for performing a specific task by a programmable device or a computing machine. The basic units or blocks of a microprocessor are The result is either stored back into memory or displayed on an output device.The microprocessor reads one instruction at a time, matches it with its instruction set, and performs the data manipulation specified.The microprocessor can be programmed to perform functions on specified/given data by writing specific instructions into its memory.Microcontrollers are also known as single microcomputers. Block Diagram of MicrocomputerĪ microcontroller is a programmable device that includes microprocessor, memory and I/O signal lines on a single chip, fabricated using VLSI technology. A microcomputer consists of microprocessor, memory, input device and output device. The microprocessor can be embedded in a larger system and can function as the CPU of the computer called a microcomputer. What are the applications of microcontroller Microcontrollers are intended for embedded devices, in comparison to the microprocessors which are used in PCs or.
Note: A microprocessor cannot perform any task on its own. This instruction set defines what the microprocessor can and cannot do. This group of operations is called an instruction set.
Nowadays many communication, digital entertainment, portable devices, are controlled by them.Įach microprocessor is designed to execute a specific group of operations. A microprocessor is an electronic device that has computing and decision-making capability. It is an electronic device that fetches instructions from memory, execute them and provide results.
