Does anyone have the knowledge of assembly language programming?  

Assembly language program is, by its nature, processor specific. If you know what processor you want to program for, there is a good list of links to tutorials in the page I give below.

While there is some value in understanding the basics of programming in assembly language, your time would probably be better spent learning an object-oriented language such as C++. This will allow you to write cross-platform programs which can be compiled for whatever OS and processor you require.

Here's the list of tutorials for assembly language: http://www.freeprogrammin...

Assembly language is not used very often as 20 years ago, but if you want to learn computer architecture or engage in embeded work, Knowing assembly language is very helpful. Learn assembly language needs more effort than other languages, because it is a little hard. But if you spend enough time on it, you will master it. Good luck!
