a) 16 pieces of 32Kx8 SRAM are connected to 8088 to address the 00000H-7FFFFH memory region. This circuit uses 3 separate decoders to select the appropriate memory regions. Draw this circuit showing the address, data and control connections. (Do not buffering.)

b) 8 pieces of 32Kx8 SRAM will be connected to the circuit in a way to form the address space C0000H-FFFFFH. Accordingly, draw the new circuit to be added to the above circuit. (You can use additional decoder or gate circuit.)
