Question
Problem 3 (25 points) 1.What is the difference between an encoder and a priority encoder? 2. Design a 4 to 2 priority encoder. The inputs are A, B, C and D. The outputs are X and Y. Let the codes be equivalent to 0, 1, 2 and 3 in order from highest to lowest priority. Input A has the highest priority followed by C then D then B. Show the following a. A symbolic representation of this priority encoder with a label that indicates the number of inputs and outputs and arrows showing the inputs and the outputs. b. A condensed truth table for this priority encoder e. A full truth table for this priority encoder (i.e. replace the X values).Explanation / Answer
1)Answer:
Encoder:
An encoder is a device, circuit, transducer, software program, algorithm or person that converts information from one format or code to another, for the purposes of standardization, speed or compression
Priority encoder:
A priority encoder is a circuit or algorithm that compresses multiple binary inputs into a smaller number of outputs. The output of a priority encoder is the binary representation of the original number starting from zero of the most significant input bit. They are often used to control interrupt requests by acting on the highest priority encoder.
Differences:
->An ordinary encoder has a number of input lines but only one of them is activated at a given time.
A priority encoder can have more than one input activated at the same time
->
Encoder: it is the device which transform data in to bits. it is the process of placing sequence of different format into special character in order to be able to transmission and storage.
Also In case of encoder binary code is used as an input it have more than one inputs line but only one as activated at a given time.
while In case of priority encoder the algorithm compress many binary inputs the result of which smaller number of outputs can be achieved.
