How power can be optimized at the program level?

Beyond eliminating obvious antipatterns, some code level optimizations decrease maintainability. Optimization will generally focus on improving just one or two aspects of performance: execution time, memory usage, disk space, bandwidth, power consumption or some other resource.

How does the assembly language improve our programming skills?

By learning assembly language, the programmer can write the code to access registers and retrieve the memory address of pointers and values. It mainly helps in speed optimization that increases efficiency and performance. Assembly language helps in understanding the work of processors and memory.

Why would you write a program in assembly language?

Assembly-language allows the designer to program in terms of the machine instructions that a specific processor can perform. Since binary machine-code instructions are difficult to understand directly, assembly-language programs are expressed in a symbolic notation.

How many assembler instructions does it take to write a program?

If an average production program has say 100k lines of code, and each line is about 8-12 assembler instructions, that would be 1 million of assembler instructions. Even if you could write all this by hand at a decent speed (remember, its 8 times more code that you have to write), what happens if you want to change some of the functionality?

What is the advantage of using assembler over writing the program?

While writing the program, if a typographical error occurred due to oversight, then also it is much easier to debug the code and find the error and rectify it. Assembler program can detects errors and can produce required error messages accordingly.

Is assembly programming more difficult to program in than C?

It seems to be a mainstream opinion that assembly programming takes longer and is more difficult to program in than a higher level language such as C. Therefore it seems to be recommend or assumed that it is better to write in a higher level language for these reasons and for the reason of better portability.

Why should I learn to write in Assembly?

When you are writing in assembly, you don’t have to write just in instruction codes. You can use macros and procedures and your own conventions to make various abstractions to make programs more modular, more maintainable and easier to read. This is where being familiar with how to write good assembly comes in.
