b) What is the maximum “stack depth” – that is, the maximum number of stack frames on the stack at any one time during the execution above? ____4____

Assume memory and registers contain the values shown at the left. Show the result in registers and memory after executing each of the MIC-1 microinstructions involved in an IJVM ILOAD 0 instruction, starting from the Main1 microinstruction.

Main1: PC=PC+1; fetch; goto (MBR)

ILOAD1: H = LV

ILOAD2: MAR=MBRU+H; rd

ILOAD3: MAR=SP=SP+1

ILOAD4: PC=PC+1; fetch; wr

ILOAD5: TOS=MDR; goto Main1
