Q32.
In which addressing mode, the effectives address of the operand is generated by adding a constant value to the content of a register?Q33.
Which of the following is/are true of the auto-increment Addressing Modes? I. It is useful in creating self-relocating code II. If it is included in an Instruction Set Architecture, then an additional ALU is required for effective address calculation III. The amount of increment depends on the size of the data item accessedQ36.
Match each of the high level language statements given on the left hand side with the most natural Addressing Modes from those listed on the right hand side. 1 A[1] = B[J]; a Indirect addressing 2 while [*A++]; b Indexed, addressing 3 int temp = *x; c AutoincrementQ37.
Which of the following Addressing Modess are suitable for program relocation at run time? (i) Absolute addressing (ii) Based addressing (iii) Relative addressing (iv) Indirect addressingQ39.
The most appropriate matching for the following pairs is: \begin{array}{ll} \text{X: Indirect addressing} & \text{1: Loops } \\ \text{Y: Immediate addressing } & \text{2: Pointers} \\ \text{Z: Auto decrement addressing } & \text{3: Constants } \\ \end{array}Q40.
A certain processor supports only the immediate and the direct addressing modes. Which of the following programming language features cannot be implemented on this processor? a) Pointers b) Arrays c) Records d) Recursive procedures with local variables
