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). Simila...

It is easier for the typical design engineer to recognize a priority encoder when it is coded as an if-else-if statement. Guideline: Coding with case statements is recommended when a truth-table-like structure makes the Verilog code more concise and readable. Guideline: In general, do not ...
Nevertheless, we shall use the term ‘priority resolver’ in this paper to refer to such a priority encoder and to distinguish it from a conventional priority encoder that has 2N inputs and N outputs. This is because no encoding is performed in an N-bit priority resolver. An N-bit ...
