How can you write a VHDL code for full adder using two half adders?
Since a fulladder can be obtained by using 2 halfadders & 1 OR gate.....so we have to call an halfadder program as well as an OR program......this can be implemented easily with the help of structural model rather than dataflow and behavoioural model

How many different four figure numbers can be made using the digits 1 9 9 1?
4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6

What is the basics of VHDL?
VHDL is a hardware description language. You can describe the hardware in three different ways using VHDL. 1. dataflow model 2. behavioral model 3. structural model
How do you construct half adder using 2 1 multiplexer?
Use the multiplexer to choose the correct output based on the inputs (use the truth table).

How can you implement an 8 to1 multiplexer by using two 4 to1 multplexers?
You don't need two 4-to-1 multiplexers. You only need one 4-to-1 multiplexer, and something that functions as a 2-to-1, like a single 2-input OR gate with one input grounded.

How many 2 input multiplexers are required to construct a 1024 input multiplexer?

Construct a 16-to-1-line multiplexer with two 8-to-1-line multiplexers and one 2-t0-1-line multiplexer?
Type your answer here... D0-D7 on 1st 8to1, D8-D15 on 2nd 8to1, S0,S1,S2 to both. The output from 1st 8to1 is D0 on the 2to1, the output from the 2nd 8to1 is D1 on the 2to1 and S3 to the 2to1. The 2to1 provides the final 16to 1 mutiplexed output, OK?
