[PDF] assume directive in 8086

The ASSUME directive tells the assembler to assume, that a certain register contains the base of some structure(in your case: segments). In your case, CS and DS point to the code segment and the data segment respectively, both the one and only of their respective kind.

  • What is assume directive?

    The ASSUME directive is. used to tell the assembler that the name of the logical segment. should be used for a specified segment. The 8086 works. directly with only 4 physical segments: a Code segment, a data.

  • What is assume assembler directive in 8086?

    ASSUME : The ASSUME directive is used to inform the assembler the name of the logical segment it should use for a specified segment. Ex: ASSUME DS: DATA tells the assembler that for any program instruction which refers to the data segment ,it should use the logical segment called DATA.

  • What is an example of assume assembler directive?

    The example of assume directive is as follows: ASSUME CS: Code, DS: Data, SS: Stack: ASSUME statement can assign up to 4 segment registers in any sequences. In this example, DS: Data means that the assembler is to associate the name of data segment with DS register.
  • Assembler directives are the commands to the assembler that direct the assembly process. They indicate how an operand is treated by the assembler and how assembler handles the program. They also direct the assembler how program and data should arrange in the memory.
