Unlike JMP instruction that does an unconditional jump, there are instructions that do a conditional jumps (jump only when some conditions are in act). These
The JA instruction will check if CF is 0. Even if you don’t use this instruction in the code given below, it will not affect the program execution as if the
operand (as set by CMP instruction). Unsigned. Algorithm: if CF = 1 then jump. Example: include ‘emu8086.inc’. ORG 100h. MOV AL, 1. CMP AL, 5. JB label1.
Program flow control · unconditional jumps. The basic instruction that transfers control to another point in the program is JMP. · Short Conditional Jumps Unlike
8086/8088MP JB N1. SUB AL , [SI + 4000H]. JMP N2. N1: MOV BL , [SI + 4000H] instructions and the operations they perform are listed below:.
For exam ple: memory, immediate 8086 instructions Page 2 of 53 REG, CF = 1 then jump Exam ple: include ‘emu8086.inc’ ORG 100h MOV AL, 1 JB label CMP AL,JB – 8086. Short Jump if first operand is Below second operand (as set by CMP instruction). Unsigned. Algorithm: if CF = 1 then jump
First, looking in array above, we see that several jumps have same flag conditions and would get same opcode. That’s why a JE instruction is equivalent to a
Description: Jumps to the destination label mentioned in the instruction if the result of previous instruction (generally compare) causes both CF and ZF to have
➢CMP Instruction. -. Compare byte or word – CMP destination, source. When 8086 executes the near CALL instruction it decrements the stack pointer by.
The JB instruction branches to the address specified in the second operand if the value of the bit specified in the first operand is 1.
JA – JZ instructions. case is executed without a jump since the actual jump takes longer to execute than falling through the test.
JA – JZ instructions. case is executed without a jump since the actual jump takes longer to execute than falling through the test.
JZ, label, Short Jump if Zero (equal). Set by CMP, SUB, ADD, TEST, AND, OR, XOR instructions. Algorithm: if ZF = 1 then jump. Example: include ‘emu8086.inc’ ORG
Short Jump if first operand is Less or Equal to second operand (as set by CMP instruction). for Signed. Jump carry (JC).
8086 will automatically generate a type 0 interrupt. When dividing a signed double word AF, OF, SF, ZF, PF, and CF are updated by the CMP instruction.
