Architectures and their assembly

Simply put, the processor, also known as the central processing unit (CPU), is quite similar to a calculator. If you look at the instructions (whatever the assembly language is), you will find many of them dealing with numbers and doing some calculations. However, multiple features differentiate processors from usual calculators. Let’s look at some examples:

• Modern processors support a much bigger memory space compared to traditional calculators. This memory space allows them to store billions of values, which makes it possible to perform more complex operations. Additionally, they have multiple fast and small memory storage units embedded inside the processors’ chips called registers.
• Processors support many instruction types other than arithmetic instructions, such as changing the execution flow based on certain conditions.
• Processors can work in conjunction with other peripheral devices such as speakers, microphones...
