There are some questions why we should understand that the present assembly language programming is there an easier and efficient. in this tutorial explains the basic structure in addition to assembly, the write that is why we use the assembly and what are the benefits?.
Why Assembly?
Assembly has several features that make it a good choice many some situations.
Assembly has several features that make it a good choice many some situations.
- It's fast – Assembly programs are generally faster than programs created in higher level languages. Often, programmers write speed-essential functions in assembly.
- It's powerful – You are given unlimited power over your assembly programs. Sometimes, higher level languages have restrictions that make implementing certain things difficult.
- It's small – Assembly programs are often much smaller than programs written in other languages. This can be very useful if space is an issue.
An assembler takes the written assembly code and converts it into machine code. Often, it will come with a linker that links the assembled files and produces an executable from it. Windows executables have the .exe extension. Here are some of the
popular ones:
- MASM – This is the assembler this tutorial is geared towards, and you should use this while going through this tutorial. Originally by Microsoft, it's now included in the MASM32v8 package, which includes other tools as well. You can get it from http://www.masm32.com/.
- TASM – Another popular assembler. Made by Borland but is still a commercial product, so you can not get it for free.
- NASM – A free, open source assembler, which is also available for other platforms. It is available at http://sourceforge.net/projects/nasm/. Note that NASM can't assemble most MASM programs and vice versa.
