As a decoder, this circuit takes an n-bit binary number and generates an output on one of the 2n output lines. It is therefore usually described by the number of addressing i/p lines & the number of data o/p lines. Typical decoder ICs might include two 2-4 line circuits, a 3-8 line circuit, or a 4-16 line decoder circuit.

A binary encoder is the dual of a binary decoder. For example, a 4-to-2 simple encoder takes 4 input bits and produces 2 output bits. The illustrated gate level example implements the simple encoder defined by the truth table, but it must be understood that for all the non-explicitly defined input combinations (i.e., inputs containing 0, 2, 3, or 4 high bits) the outputs are treated as don't cares A block diagram of decoder consists input lines, one or more enable inputs and maximum number of output lines. To construct a decoder, we require to know the number of all possible output lines that totally depends on the given input. So, if n represents given input lines then possible output lines would be 2 n . Decoder with two inputs would give 4 outputs (n=2,2 2 that is 4). Step 1. Now we know possible outputs for 2 inputs, so construct 2 to 4 decoder , having 2 input lines, a enable. A 4:2 Priority Encoder If two or more inputs are given at the same time, the input having the highest priority will take precedence . [1] An example of a single bit 4 to 2 encoder is shown, where highest-priority inputs are to the left and x indicates an irrelevant value - i.e. any input value there yields the same output since it is superseded by higher-priority input
A 4:2 priority encoder has four inputs and two outputs like a normal binary encoder. The difference lies in the truth table. For a priority encoder, the output is dependant on the highest priority bit. For example, if I7, I6, and I0 bits of an 8-bit input are high, then the output (111) will be for I7. Let's write the truth table for a 4:2 priority encoder 4 to 2 Line Encoder. This encoder has 4 input lines and 2 output lines. A single input line can be high at a time otherwise the output will be ambiguous. Block diagram of 4 to 2 line binary encoder is given below logic circuit for priority encoder. We have to structurize each gate with their respective module. Structural Modeling of 4:2 Priority Encoder. To start with code, we will first structurize the OR gate. We declare the module as or_gate. Then, we declare input and output ports. module or_gate(c,a,b); input a,b output c The four-bit encoder allows only four inputs such as A0, A1, A2, A3 and generates the two outputs F0, F1, as shown in below diagram 4 to 2 priority encoder. A 4-to-2 priority encoder takes 4 input bits and produces 2 output bits. In this truth table, for all the non-explicitly defined input combinations (i.e. inputs containing 2, 3, or 4 high bits) the lower priority bits are shown as don't cares (X). Similarly when the inputs are 0000, the outputs are not valid and therefore they are XX. From the above truth table, we can.

Therefore, the outputs of 2 to 4 decoder are nothing but the min terms of two input variables A 1 & A 0, when enable, E is equal to one.

VHDL Code for 4 to 2 encoder A priority encoder is an encoder circuit in which inputs are given priorities. When more than one inputs are active at the same time, the input with higher priority takes precedence and the output corresponding to that is generated. Let us consider the 4 to 2 priority encoder as an example. From the truth table, we see that when all inputs are 0, our V bit or the valid bit is zero and outputs. Circuit Description.
