The movs instruction takes four basic forms. Movs moves bytes, words, or double words, movsb moves byte strings, movsw moves word strings, and movsd moves double word strings (on 80386 and later processors). These four instructions use the following syntax: {REP} MOVSB {REP} MOVSW {REP} MOVSD;Available only on 80386 and later processors {REP} MOVS Dest, Source The movsb (move string, bytes) instruction fetches the byte at address ds:si, stores it at address es:di, and then increments or decrements the si and di registers by one. If the rep prefix is present, the CPU checks cx to see if it contains zero. If not, then it moves the byte from ds:si to es:di and decrements the cx register. This process repeats until cx becomes zero. In this assignment, you will implement the X86 Prefix instruction REP MOVS in all forms using any high level language
