A register stack has 256 words is shown below. The stack pointer SP points at the top item in the stack. When the stack is empty, the value of SP is 0. The stack grows with increasing addresses. The Flip-Flop FULL is set ( FULL = 1) when the stack is full, and the Flip-Flop EMPTY is set (EMPTY = 1) when the stack is empty. Answer the questions below: RTL. for PUSH and POP Address 2255 1254 FULL EMPTY PUSHI SP M[SP) SP1 DR SP POP DR SP NESP) SP-1 a. What is the size of the stack pointer SP (in bits)? b. Find the values of SP FULL and EMPTY for the different situations listed in the table below: b Find the values of SP, FULL and EMPTY for the different situations listed in the table below: Value of SP Value of FULL Value of EMPTY Situation SP = 0, EMPTY = 1 and PUSH operation is performed SP = 255 and PUSH operation is performed SP = 0, FULL = 1 and POP operation is performed SP = 12, EMPTY = 0 and POP operation is performed Il
