Consider this program fragment:

i := 0;
sum := 0;
while i<n do
   { sum := sum + i;
     i := i + 1;
   }
a := sum;

Which of the following is a correct translation from high to low level?

Suppose R1 contains 00c6 and R2 contains 0dc1.

What is the effective address in this instruction?

lea  R2,8[R1]

Give the answer as a single hex word, with no $.

Example format of answer: f32b (four consecutive hex digits)

The variable p is a pointer to a record x. Which instruction puts p into R8?

What is the label of the instruction that will be executed

after the following code executes?

    lea   R5,JT[R0]
    lea   R4,3[R0]
    add   R4,R4,R4
    add   R4,R5,R4
    jump  0[R4]
JT  jump  placeA[R0]
    jump  placeB[R0]
    jump  placeC[R0]
    jump  placeD[R0]
    jump  placeE[R0]
    jump  placeF[R0]
placeG
