Abstract

The invention of low-cost computers based on integrated circuits revolutionised modern society. The ‘Microprocessors (µP)’ can now be found in complex systems like spacecraft electronics to household devices such as smart refrigerators and to a simple toy. A microprocessor plays a vital role in programming an IoT based system. It is the core central unit responsible for computing and processing the on-board tasks. Microprocessors are usually embedded on a single integrated circuit or a small number of ICs. Combinational and sequential logic, both can be computed by a microprocessor. It performs operations with an ALU (Arithmetic Logical Unit) and also runs communication with multiple devices in a connected network.
