PROBLEMS 235
(b) Obtain the optimized two-level SOP results for the two functions and compare
them with the results of part (a) by using the gate/input tally (including inverters)
assuming that the inputs and outputs are all active high.
(c) Construct the logic circuits for the circuits of parts (a) and (b).
5.16 (a) Use subfunction partitioning of the following function for CRMT/two-level min-
imization in minterm code. To do this, collapse this function into a third-order
K-map of axes A, B, C and follow the discussion given in Section 5.11. Choose
{A, B, C} as the bond set for the CRMT portion.
F(A, B, C, D, E) =
m(4, 7, 10–12, 14, 16–19, 21, 23, 24–27, 28, 30)
(b) Without partitioning, use the CRMT method to obtain a gate-minimum for this
function. ...
