The function table shows different functions this ALU performs for different values of F (a 3-bit control signal). A multiplexer (or mux) is a common digital circuit used to mix a lot of signals into just one.If you want multiple sources of data to share a single, common data line, you'd use a multiplexer to run them into that line. By signing up, you are agreeing to our terms of use. If n is 4, then it becomes a 4-bit shift register. 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). University of Maryland, College Park. sum[31:0]). The code follows Behavioral modelling. The easy solution is to create a rotate left unit, a rotate right unit, a shift left unit, and a shift right unit and finally an output select mux.
