Calculator Logic Inputs

I've already started this mini project with the 4x1 Mux, it just needs to be finished. This shouldn't take very long, please serious bids only.


For the calculator, it will need a 4x1 multiplexor (mux) with four 8-bit inputs and an 8-bit output. For this project, however, 4-bit inputs and a 4-bit output are sufficient. In other words, using a pair of selector bits your mux should be able to pass through a single 4-bit input as the 4-bit output. To start, it should implement a 4x1 mux with 1-bit inputs and a 1-bit output in as a subcircuit.

A 4x1 mux with 2-bit inputs can be made using a pair of 4x1 muxes with 1-bit inputs where each bit of the output is selected by a different mux. A 4x1 mux with 4-bit inputs can then similarly be made using a pair of 2-bit 4x1 muxes.

Priority Encoder:

A priority encoder takes a specific number of input bits and represents the position (meaning the power of two exponent) of the most significant bit that is set (the bit farthest to the left that has a value of 1) in binary. Your priority encoder will have four 1-bit inputs and three 1-bit outputs: two bits used for the representation, in binary, of the position of the highest bit set and a valid bit that is 1 if at least one input bit is set.

As one example of a potential input and expected output, suppose all 4 input bits are merged into a single binary representation of 01102. In this case the binary output should be 102 (which is equal to 210) and the valid bit should be 1. This output is generated because the bit in the 22 position is set.

Although the 21 position bit is also set, it does not affect the output because it is not the most significant set bit. As another example, if the input is 00102 then the output would be 012 (= 110).

For the person chosen, I will give further details.
