Question
Consider the problem of implementing signed overflow detection for an integer subtraction operation c = a - b. Denote the leftmost bits of the operands by a31 and b31, and the leftmost bit of the computed result by c31. Complete the following logic equation: аз1. + (not a31). so that it has value 1 if signed overflow has occurred and has value 0 otherwise. Do this by dragging two items from the below list into the correct spaces. (Here the "not" operator is denoted with the word "not" rather than with an overbar, e.g. (not A) rather than Ā.) (not b31) . (not c31) b31. (not c31) b31. с31 not (b31 . c31) (not b31) . c31
