What is loop instruction in 8086?
LOOP ? Used to loop a group of instructions until the condition satisfies, i.e., CX = 0. LOOPE/LOOPZ ? Used to loop a group of instructions till it satisfies ZF = 1 & CX = 0. LOOPNE/LOOPNZ ? Used to loop a group of instructions till it satisfies ZF = 0 & CX = 0. JCXZ ? Used to jump to the provided address if CX = 0.
What is looping instructions?
There are two types of looping instructions: repetitive loops and conditional loops . All loops, regardless of the type, begin with the DO keyword and end with the END keyword. Repetitive loops let you repeat instructions a certain number of times. Conditional loops use a condition to control repeating.
What is the use of loop instruction in microprocessor?
The LOOP instruction assumes that the ECX register contains the loop count. When the loop instruction is executed, the ECX register is decremented and the control jumps to the target label, until the ECX register value, i.e., the counter reaches the value zero.
Operand types: REG: AX, BX, CX, DX, AH, AL, BL, BH, CH, CL, DH, DL, DI, SI, BP, SP. SREG: DS, ES, SS, and only as second operand: CS.
