A purpose of Exercise was to demonstrate that it is not always possible to maintain consistency in active-level notation unless you are willing to define alternate logic symbols for MSI parts that can be used in different ways. Define an alternate 74x148 symbol that provides this consistency in Exercise.
Exercise
Draw the logic diagram for a circuit that resolves priority among eight active-low inputs, 10_L–17_L, where 10_L has the highest priority. The circuit should produce active-high address outputs A2–A0 to indicate the number of the highest-priority asserted input. If at least one input is asserted, then an AVALID output should be asserted. Be sure to name all signals with the proper active levels. This circuit can be built with a single 74x148 and no other gates.
We need at least 10 more requests to produce the solution.
