Role of an emulator in microprocessor:

 Role of an emulator in microprocessor:

1. It is used to test and debug the hardware and software of an external system, such as the prototype of a microprocessor – based instrument.
2. Part of the hardware of an emulator is a multiwire cable which connects the host system to the system being developed. A plug at the end of the cable is plugged into the prototype system in place its microprocessor.
3. Through this connection the software of the emulator allows you to download your object code program into RAM in the system being tested and run it.
4. Link a debugger, an emulator allows you to load and run programs, examine and change the contents of memory locations, insert breakpoints in the program.
