Today, in this blog post, we will discuss What is Mnemonics in Microprocessors?
We all know that the microprocessor is the heart of any digital device, such as computers, smartwatches, smartphones, etc. Without a microprocessor, these devices would almost certainly not function.
These devices largely rely on microprocessor functionality, much like the human body depends on the heart. The absence of a microprocessor renders an electronic device inoperative, akin to a human body without a heart.
But have you ever wondered how a microprocessor operates? We often hear that computers understand machine language.
In reality, it is the microprocessor that understands machine language, which is the language of 0s and 1s, also known as binary numbers.
Since the microprocessor only understands machine language, the instructions for these tasks must also be given in binary form.
However, it is difficult for humans to remember binary codes like 011100000001111111 because these codes vary for each task.
Therefore, humans have created Assembly Language, in which binary signals, i.e., 0s and 1s, are replaced with words and numbers that are easier for humans to recognize and remember. These words and numbers are called mnemonics.
For example, “ADD” is used for addition, “SUB” for subtraction, and “INC” for increasing by one. This is why Assembly Language is also known as Symbol Language, and writing programs in Assembly Language becomes more accessible for programmers and easily understandable by users.
However, computers do not understand programs written in Assembly Language. Computers only understand binary signals, i.e., 0s and 1s.
Therefore, programs written in Assembly Language are translated into Machine Language. This translation is performed using a Programming Language Translator, also known as an Assembler.
An Assembler is a Language Translator who translates Assembly Language into Machine Language.
Thus, due to “mnemonic code,” programming and understanding Assembly Language becomes simpler.
