In the game of 10-pin bowling the bowler has two attempts to knock down pins for every frame of 10-pins, and scores a point for each pin knocked down. If all the pins are knocked down with two attempts, the bowler gets a bonus - whatever score they obtain with their next bowl is doubled. If all the pins are knocked down on the 1st attempt, no 2™d attempt is allowed, and the bowler gets a bonus – whatever score they obtain on their next two bowls are doubled. A student attempts to capture this scoring system in VHDL code, a fragment of which is shown in Figure Q4. Q4 (a) Draw the state transition diagram described by the VHDL of Figure Q4.

Question
In the game of 10-pin bowling the bowler has two attempts to knock down pins for every frame of 10-pins, and scores a point for each pin knocked down. If all the pins are knocked down with two attempts, the bowler gets a bonus - whatever score they obtain with their next bowl is doubled. If all the pins are knocked down on the 1st attempt, no 2nd attempt is allowed, and the bowler gets a bonus – whatever score they obtain on their next two bowls are doubled. A student attempts to capture this scoring system in VHDL code, a fragment of which is shown in Figure Q4. Q4 (a) Draw the state transition diagram described by the VHDL of Figure Q4. Discuss whether the VHDL of Figure Q4 correctly scores a game of 10-pin bowling. (b) elsif CLK='1' and CLK'event and UPD='1' then case present state is when throwl => frame := frame + 1; + resize (unsigned (N), 9) score := score if N = w1010" then present state <= throwl-strike; else present_state <= throw2; end if; when throw2 => score := score + resize (unsigned (N), 9) present state <= throwl; if N = "1010" then present_state <= throwl-spare; end if; when throwl-spare frame := frame + 1; score := score + resize (unsigned (N),9) => + resize (unsigned (N),9) if N = "1010" then present_state <= throw1-strike; else present state <= throw2; end if; when throwl-strike => frame := frame + 1; score := score + resize (unsigned (N),9) size (unsigned (N), if N = "1010" then present_state <= throwl-strike; else present-state <= throw2; end if; end case; end if; Figure Q4
