Microprocessor understands only machine level language. We will develop the source code using higher-level programming languages like C or any other Assembly language into an Integrated Development Environment (IDE). The IDE will covert our source code into machine level language which the microprocessor will understand.

Let us now learn how to program a microprocessor step by step.

Selection of a suitable programming language: Firstly, you need to select a language for developing your source code. You need to choose a suitable high-level programming language like C  or Assemble level language. 

Integrated Development Environment (IDE): After selecting the suitable programming language, the next step involves writing the source code in an IDE. IDE consists of different types of tools like code editors, compilers, various debugging tools, etc. IDE compiles the code written by us into a machine-understandable code. 

Test Run: After embedding the source into the IDE, now you need to perform a test run of the developed code using the IDE simulation package. IDE simulator scans our source code line by line for any errors. In case of any errors, IDE performs all necessary debugging to make our source code ready for execution.

Attaching freestanding program: After necessary debugging, now you need to add a freestanding (standalone program) to your computer which is used for booting the bootstrap mechanism of our concerned processor.

Embedding the developed source code: Now its time for us to embed our program into our microprocessor. This is done with the help of IDE. Select the developed program from the dropdown list and add it to the microprocessor. If you are using old microprocessors, then firstly you need to erase the pre-installed program before adding the new one.

In spite of all the debugging, several run time errors may pop-up. You need to modify your source code and perform all necessary debugging until the program becomes completely error-free.
