return for 16 to one using two 8 to 1, you use an and gate to choose which multiplexer(the forth control input besides the 3 control input in the 8 to 1 mux), then connect the two 8 to 1 multiplexer output to an or gate output. Clear if CLR is asserted (overrides loading and counting). Decoder outputs and the enable inputs are active HIGH. The multiplexers should be interconnected and inputs labeled so that the selection codes 0000 through 1001 can be directly applied to the multiplexer selections inputs without added logic. Automatic Generation and Evaluation of Transistor Networks in Different Logic Styles Thesis presented in partial fulfillment of the requirements for the degree of Doctor in Microelectronics. Implement using a 4:1 multiplexer (Place A,C on the select inputs, Assume B', D' are available and use an XOR gate to form one of the inputs to the multiplexer.

Simple 4 : 1 multiplexer using case statements Here is the code for 4 : 1 MUX using case statements. While XOR or LUT based implementations o er a means to increase security, the per-gate area, power, and performance encryption overhead is high. The input signals x and y in the AND and OR gates may exist in one of four possible states: 00, 10, 11, or 01. If we choose to connect A, B,and C to the inputs of the Multiplexer, then for each combination of A, B and C, ECE 241 Logic Circuit Lab Lab #4; Page 2/11 Spring 2007 although only one Mux input is selected. If the code is 000, then I will get the output data which is connected to the first pin of MUX (out of 8 pins). buf stands for a buffer and simply transfer the value from input to the output without any change in polarity. You'l need 5 4 to 1 muxes for making a 16 to 1 mux if your inputs are say W(0)-W(15) i. The input and output sections consist of 4x1 and 2x1 multiplexers and ALU is.
