VCET-EEE Dept created by C.GOKUL AP/EEE Instruction set of 8086 Microprocessor STD: o It sets the The co-processor will treat normal 8086 instructions as NOP.
Instruction Set of 8086 An instruction is a binary pattern designed inside a microprocessor to perform a specific Processor Control Instructions STD:
After a CMP instruction, OF, SF, ZF and CF are set appropriately. For example, (using STD) then the 8086 will decrement SI and DI after each iteration.
Strings and Character Sets Chapter 15 This chapter explores some of the uses of these string instructions. The 8088, 8086, or std before a string instruction:
'std', 'cld, affect direction flag OR, AND, NOT can toggle the bits in a direction flag
Clear Direction Flag (cld) cld Operation. 0 -> DF . Description. Clears the direction flag; affects no other flags or registers. Causes all subsequent string
This chapter explores some of the uses of these string instructions. The 80x86 CPUs can process three types of strings: and STD (set direction flag) instructions.

In case it is set to 1 (using the set-direction-flag instruction STD) — the string is processed from highest to lowest address.This is called auto-decrementing mode.
