Demultiplexer with vhdl code 1. Title: 1:4 Demultiplexer using Xilinx Software: Xilinx ISE I. Introduction Demultiplexer (Demux) The action or operation of a demultiplexer is opposite to that of the multiplexer. As inverse to the MUX , demux is a one-to-many circuit. It is necessary because the mux assignment cover only 3 of the 2^32 possible integer values. If we try to layout the code, it is interesting to see how RTL viewer interprets the VHDL code: Altera RTL Viewer of 4-way-mux using select clause. This case is different from the previous one.

Multiplexer is one of the basic building units of a computer system which in principle allows sharing of a common line by more than one input lines. VHDL code for 8:1 Multiplexer. - Free download as PDF File (.pdf), Text File (.txt) or read online for free. 8:1 Multiplexer The multiplexer is a combinational circuit which accepts several data inputs and allows only one of them at a time to get through to the output. Design the VHDL components (Register, Decoder, and two Multiplexer 16 bit) and interconnect them to build a register file. The schematic shows only four registers. Your solution should implement eight registers. The diagram provided as a example uses a 2:1 and 4:2 multiplexer, this dealt with 4 bits.
In any case, you have to combine the outputs of the 16 AND/NAND gates to form the complete multiplexer. I see, that the popular VHDL text book enoch o. hwang, digital logic and microprocessor design with vhdl uses also a "structural" NOT gate for it's 2-to-1 multiplexer. VHDL Tutorial. 1. ...
