Question 1 The static RAM 6264 is located starting at address 9E000 of the 8086 address space as shown in the figure below. a) What is the value of n? (see the notes below) b) Show the address decoding circuitry adding external logic gates if necessary. You can use the table below to analyze the address. • You must show all the connections to A, B, C, (G2A), (G2B), and G1. • The address lines connected to the 6264 are indicated by n and the data lines are indicated by d. You must also show the connection between the 74LS138 and the 6264 clearly on the figure below. 7415138 G2A GZB GI S Outputs n 1888 CE 6264 A19 A18 A17 A16 A15 A14 A13 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 AO

Design a combinational circuit using multiplexer for a car chime based on thefollowing system: A car chime or bell will sound if the output of the logic circuit(X) is set to a logic ‘1’. The chime is to be sounded for either of the followingconditions:• if the headlights are left on when the engine is turned off and• if the engine is off and the key is in the ignition when the door is opened.Use the following input names and nomenclature in the design process:• ‘E’ – Engine. ‘1’ if the engine is ON and ‘0’ if the engine is OFF• ‘L’ – Lights. ‘1’ if the lights are ON and ‘0’ if the lights are OFF• ‘K’ – Key. ‘1’ if the key is in the ignition and ‘0’ if the key is not in the ignition• ‘D’ – Door. ‘1’ the door is open and ‘0’ if the door is closed• ‘X’ – Output to Chime. ‘1’ is chime is ON and ‘0’ if chime is OFF
