Write a verilog program for 2 to 4 decoder A decoder is a multiple input, multiple output logic circuit that converts coded inputs into coded outputs where the input and output codes are different. The enable inputs must be ON for the decoder to function, otherwise its outputs assumes a ‘disabled’ output code.

Since I am using two 3-8 decoders to develop a 4-to-16 decoder, I want to use 4 inputs out of the two 3-8 decoders. So I'll use all three of the first and the first of the second, and connect the last two inputs to ground, since they won't be used. Write a verilog program for 2 to 4 decoder A decoder is a multiple input, multiple output logic. So here consuming e to end up being 4, t is also, so we will possess $2^t$ therefore $2^4 = 16$ AND entrance amp; 2 decoders each of size $2^k/2$ so $2^2 = 4$. So we have 16 AND entrance amp; two 2x4 decoders In case then-bit coded data has idle bit combinations, the decoder may have less than 2n outputs. 2-to-4, 3-to-8 line decoder or 4-to-16 decoder are other examples. The parallel binary number is an input to a decoder, used to notice the occurrence of a particular binary number at the input

How to build a 4x16 decoder using ONLY two 2x4 decoders? Following the steps we took in the lecture, we are supposed to build a 4x16 decoder. So here taking k to be 4, k is even, so we will have $2^k$ so $2^4 = 16$ AND gates & 2 decoders each of size $2^{k/2}$ so $2^2 = 4$. So we have 16 AND gates & two 2x4 decoders Decoder Design Using Predecoding •Example: 256-output (8 input bits) with predecode -Ex: take groups of 2 input bits •Four possibilities; activate one of four wires (use 2 INVs, 4 ANDs) -Wires along array: 22 * (8/2) = 4 groups of 4 = 16 (same as non-predecoded) -Each output uses a 4-input AND gate (much faster Binary decoder has n-bit input lines and 2 power n output lines. It can be 2-to-4, 3-to-8 and 4-to-16 line configurations. Binary decoder can be easily constructed using basic logic gates.

Assignment specifications • Use JK flip-flops and suitable logic gates to design a 4-bit binary Gray code generator. • Use the output of the Gray code generator as inputs to a combinational logic circuit to decode the Gray code to produce the normal binary counting sequence
  • In a 4:2 encoder, the circuit takes in 4 bits of data as input. It then codes the data to give an output of two bits. Here, we will be writing the VHDL code for a 4:2 encoder using the behavioral modeling style of architecture
  • As there are 32 outputs in 5-to-32 decoder so I will have to use 32/4 = 8, 2-to-4 decoder. But then I have total 16 inputs. As I want to create 5-to-32 decoder so I need only 5 inputs, what do I do.

Using only three 2-to-4 decoders with enable and no other additional gates, implement a 3-to-8 decoder with enable. The inputs of the resulting 3-to-8 decoder should be labeled X[2.0] for the code input and E for the enable input. the outputs should be labeled Y[7.0]. Here's my current solution Create a Verilog module called decoder_3_8 with inputs I and output Y as follows: 1 module decoder_3_8 ( 2 input [2:0] I, 3 output [7:0] Y . 4 ); The most efficient way to describe the behavior of a decoder is to use a case statement in an always block. 1 reg [7:0] Y; 2 . 3 always @ (I) 4 begin . 5 case (I) 6 3'd0 Verilog source codes Low Pass FIR Filter Asynchronous FIFO D FF without reset D FF synchronous reset 1 bit 4 bit comparator Binary counter BCD Gray counter T,D,SR,JK FF 32 bit ALU Full Adder 4 to 1 MUX DEMUX binary2Gray converter 8to1 MUX 8to3 Encoder Logic Gates Half adder substractor 2to4 decoder
