![]() This is a special type of encoder, used to eliminate the problem associated with normal encoders. ![]() Thus, this is all about an overview of the priority encoder. Using a PPC (parallel prefix computation), improves calculation as well as circuit timing. These are frequently used once several components share a common resource otherwise within interrupt controllers.Priority encoder converts several binary inputs into the binary depiction of the active input bit index through the maximum priority.So priority encoder defeats this drawback of the encoder and it provides a coded output through allocating a priority toward the input bits. In that situation, the encoder changes to a digital code from the angular location of a compass. Another common application is magnetic positional control which is utilized in the positioning of the robotic arm as well as navigations of the ship.This also controls the interrupt requests by performing on the maximum priority demand to encode the flash analog output to the digital converter.For example, suppose a microcomputer wants to read the standard QWERTY keyboard that includes 104 keys wherever simply one key would be pushed either LOW or HIGH at any one time. ![]() In electrical and electronic circuits, priority encoder is used to reduce the requirement of connecting wires or application that includes several inputs.Thus, this kind of encoder is used to decrease the number of required connections within a specific application where there are several inputs. A larger priority encoder can be designed through cascading different priority encoders. A priority encoder is used in different applications as compared with the normal digital encoder.The applications of the priority encoder include the following. An encoder includes several input lines however only one of them is turned on at a specified time whereas a priority encoder includes above one input turned on at the same time.Once input through a maximum priority is there, then all the remaining inputs through a lesser priority will be neglected. ![]()
