The String Instructions. Module 11. CS 272. Sam Houston State University Dr. Tim McGuire. String Instructions. A string is simply an array of bytes or words; Here are some operations which may be performed with string instructions. copy a string into another string; search a string for a particular byte or word; store characters
Strings are usually arrays of bytes, words, or (on 80386 and later processors) double words. The 80x86 microprocessor family supports several instructions specifically designed to cope with strings. This chapter explores some of the uses of these string instructions. The 80x86 CPUs can process three types of strings: byte
The 8086 microprocessor supports 8 types of instructions ?. Data Transfer Instructions; Arithmetic Instructions; Bit Manipulation Instructions; String Instructions; Program Execution Transfer Instructions (Branch & Loop Instructions); Processor Control Instructions; Iteration Control Instructions; Interrupt Instructions. Let us now
String Instructions. The string instructions facilitate operations on sequences of bytes or words. None of them take an explicit operand; instead, they all work implicitly on the source and/or destination strings. The current element (byte or word) of the source string is at DS:SI, and the current element of the destination string is

one of 8086 processor control flags. controls the direction of string operations: DF = 0 => forward (left to right) processing; DF = 1 => backward (right to left) Moving (Copying) Strings. Instructions: MOVSB - copies contents of BYTE given by DS:SI into ES:DI MOVSW - copies contents of WORD given by DS:SI into ES:DI
String Manipulation Instructions. A series of data byte or word available in memory at consecutive locations, to be referred as Byte String or Word String. A String of characters may be located in consecutive memory locations, where each character may be represented by its ASCII equivalent. The 8086 supports a set of more
21 Dec 2015 Strings and String Handling Instructions : The 8086 microprocessor is equipped with special instructions to handle string operations. By string we mean a series of data words or bytes that reside in consecutive memory locations. The string instructions of the 8086 permit a programmer to implement
