Raykumar, it is very hard to expect that somebody else will solve your dilemma, your problem is very easy, you need to search on google and read datasheet for 74HC194, it is 4bit bidirectional Sh. R.,
but probably will be better and much easier to use 74HC595 for led moving display,
you also ask for code in asm, without your schematic it is not possible to make a code....
best regards
