Prelab

Prelab for this week is optional. However, it needs to be completed after the material is taught in the lab section.

Review ROM based design of combinational circuits.
Complete the following:

• A truth table illustrating the relationship between [I7,...I0]  as inputs, and [X2, G2,...A2], [X1, G1, ....A1], [X0, G0,...A0] as outputs that drive the 3 7-segment displays for the following five input combinations:  [I7,...I0] =  0000 0000;   0000 1010;  0010 0100;  1000 1000;  1111 1111;
• Create a table that contains the address of the memory location [I7,...I0], and the contents [X2,G2,...X1,G1,...,X0,G0,...A0]of that specific location in hexadecimal form for the above five combinations.
