I have to complete this circuit with the necessary address resolution circuitry (using the required address, control pins and necessary logic gates). Connections should be the following values:
1011 1110 value to 74LS373
1011 1111 value to 74LS245
I need help please, someone help. Thanks.

 

Can't understand the request.

Post the full text of the problem and your work.

There are even number 10111110B and odd number 10111111B.
I need to complete the necessary address resolution circuitry with logic gates, control lines etc.
Even number should be connected to 74LS343(top right in the pic). Odd number should be connected to 74LS245 component(bottom right in the pic).
When I press A button and left it, LEDs on the OUTPUT unit must be shifted to the right. When I press B button and left it, LEDs on the OUTPUT unit must be shifted to the left.
That's all. Could you help me, please

 

I'd give you a clue...

Since A7 to A0 is 1011111X binary only different is the A0 bit. You can use an 8 input NAND gate plus a NOT gate to decode the leftmost 7 bits.

M/IO should be low as they are IOs.
RD should be low for the switches and WR should be low for the LEDs.
Not sure about BHE but I think it should be low too. Read the datasheet of 8088 and see what it does.
