To understand the working of an Integrated Circuit, we need to first understand what an Embedded System is.  It is basically a conjunction of Hardware and Software parts. Embedded System is a stripped-down version of a mainstream computer, specializing in a single task. They are connected either as a standalone device, or as part of a larger electrical or mechanical system. Mainly in consumer electronics like fridges or microwaves, they have low power rating and, is economical to build. Embedded system performs complex mathematical calculations at any specific time. This is done thru a Central Processing Unit (CPU) , mostly a Microcontroller or at times, a Microprocessor. A Sensor is used to collect data from the external environment Eg: Temperature, atmospheric pressure etc. This is then fed into an Analog to Digital (ADC) converter. The digital signal thus obtained is stored in memory and, decoded by the CPU.  The output of the operation is then fed to a Digital to Analog...
