Emulators and simulators

Microcontrollers are developed to perform arithmetic and logical operations at relatively faster rate. Emulators in a microcontroller perform some tasks which are used for developing some advanced applications. A programmer can probe the functional aspects of a microcontroller using emulators. Emulators also allow the execution and monitoring of software in small steps. This process is known as single stepping mode. This procedure helps to put break in the program whenever we want to test sections of software at a time. The emulators also consist of performance analyzers which indicate the efficiency of the programs and gives suggestion for corrections. Simulators are software tools loaded in a microcontroller which allows testing simple arithmetic manipulations and mathematical algorithms. Since hardware is not required for a simulator in a microcontroller, this method turns out to be a safe method for testing programs especially for the beginners in this field.
