Priority Encoder Circuit Diagram. The output of a priority encoder is the binary representation of the original number starting from zero of the most significant input bit. A priority encoder is a circuit or algorithm that compresses multiple binary inputs into a smaller number of outputs.
Y3 y2 y1 y0 and 2 outputs. Priority encoder a 4 to 2 priority encoder has 4 inputs. Out of the four input d3 has the highest priority and d0 has the lowest priority.
Priority is given to the input lines.
The block diagram of a 4 2 priority encoder is shown below a priority 4 2 encoder also has 4 inputs and 2 outputs but we will add another output called v which stands. Priority encoders are used extensively in digital and computer systems as microprocessor interrupt controllers where they detect the highest priority input. They are often used to control interrupt requests by acting on the highest priority interrupt input. Implementation of the 4 to 2 priority encoder using combinational logic circuits.
