Question

What is indirect program memory addressing? Explain the working of the following instructions?

Answer 1

• Indirect main memory addressing is described as the method in which the variable's address is stored in a mind register and also a command is utilized to point towards the memory registers which hold the register.
• Instruction is used to direct towards a register that displays the results of the variables.
• The register, in turn, refers to that variable's address in simplistic words. As just a result, it is indeed considered a passive program, memory address.

The instructions operate as follows:

a)

JMP AX :

• The JMP instruction is being used to execute an unconditional jump.
• AX is indeed the label's name.
• JMP AX codes are being used to transfer control of the flow program to the AX label.

b)

JMP LIST:

• The JMP command can be used to execute an unconditional jump, JMP LIST[DX] is the label's name.  
• The JMP LIST[DX] program is being used to transfer control of its flow programs to the specified section.
• It is the segment to which the flow control is transmitted.

c)

JMP NEAR PTR[DI+3]: 

• Unconditional jumps could be done with the JMP command as you'll see, the label is JMP NEAR PTR[DI+3].
• It's being used to transmit flow control to a particular section, throughout this case [DI+3].
• The close keyword indicates that perhaps the code segment would be in the line of code being nearby.
