Problem #4

Use the register and memory values in the table below for the next questions. Assume a 32-bit machine. Assume each of the following questions starts from the table values; that is, DO NOT use value changes from one question as propagating into future parts of the question.

a) Give the values of R1, R2, and R3 after this instruction: add R3, R2, R1

b) What values will be in R1 and R3 after this instruction is executed: load R3, 12(R1) c) What values will be in the registers after this instruction is executed: addi R2, R3, #16
