- 62. For the base and offset addresses in problem 61, how many words of data are cur- rently held in the stack?Q-6: A main program consists of two procedures begins at memory address 7000H. Procedure-1 begins at begins at 6000H and Procedure-2 begins at 8000H respectively. Procedure-1 is called within Procedure-2 at memory address 8050H. In the main program Procedure-1 is called at 7040H and Procedure-2 is called twice: first at 7060H and then at 70AOH. Please note that Stack is used to save return addresses at the instants of procedure calls. Show the state of Stack while the program runs.Let us assume that, the stack pointer ($sp) has value Y, just before the procedure starts. Give the value, of the stack pointer, with respect to Y, after the procedure saves the appropriate registers on stack. Give the value and explain why. Give the value, of the stack pointer, with respect to Y, after the procedure restores the saved registers from stack. Give the value and explain why.

If the current values in the stack segment register and stack pointer are C00016 and FF0016, respectively, what is the address of the current top of the stack?3. The table below represents a stack stored in a contiguous block of memory cells (as discussed in the text). If the base of the stack is at address 0x10 and the stack pointer contains the value 0x12, what value is retrieved by a pop instruction? What value is in the stack pointer after the pop operation?

Contrast the difference between a compiler, assembler, and linker What is the difference between the data segment and the text segment of in an assembly language program? What register is used as the stack pointer? What is a ebreak instruction in the sample program? How would you define a constant named 'BLUE' and assign it to the value OX00F in assembly language? Describe how to implement the psuedo-instruction li t1, e using a native instruction.ADD [R1], R2, [R3]; Here [R1] and [R3] indicate memory locations pointed by R1 and R3 register respectively. Here the operand field next to opcode will hold the result at the end. Assume that the machine code of this instruction is loaded at address 1020H of the main memory. Also assume that the contents of registers R1, R2 and R3 are 2001H, 2002H and 2003H respectively.
