A stack where the stack pointer is updated with every operation is more efficient than a stack where the data moves after each operation since the cost of changing the contents of the stack pointer is much less than the cost of moving all the data.

True

False

The only difference between JSR and JSRR is the addressing mode used for evaluating the starting address of the subroutine.

True

False

In the LC-3, the JSRR instruction can jump to any memory location, from x0000 to xFFFF.

True

False

Changing R7 without saving its contents during a service routine is problematic as it destroys the linkage back to the initiating program.

True

False

In a stack with a capacity of 3 elements, three pushes followed by four pops results in an overflow.

True

False

If R6 is the stack pointer and each element in the stack occupies two memory locations, a push operation on the stack requires that R6 be decremented by 2.

True

False

Given an empty stack and this sequence of operations performed on the stack, what is the last value popped?

If R6 is the stack pointer and contains the value x4001, and R0 contains the value to be pushed onto the stack, what will be the contents of R6 after this push routine:

X4002

X4001

X4000

X4003

If R6 is the stack pointer, and the stack grows towards zero, what is wrong with the following pop routine:

Nothing is wrong.

R6 should be incremented, not decremented.

the value of R6 is written to R0, not the contents of the memory location pointed to by R6

R6 should be incremented twice, not once

Assume that the stack grows towards zero, the stack pointer is R6 and contains x4000. What are the contents of R6 after the following operations:

X4002

X3FFF

X3FFE

4001

. In a FIFO data structure, the elements are inserted at the top and removed from the bottom. What is the last value removed after execution of the following:

R6 is the stack pointer. What are the contents of R0 after this operation: LDR R0, R6, #0

The stack pointer

The value of the top of the stack

The value of the bottom of the stack

. In a JSR instruction, what is the maximum offset you can jump to from the JSR instruction location:
