Consider the two 8-bit numbers A = 10110110 and B = 00110111. (a) Give the decimal equivalent

Question:

Consider the two 8-bit numbers A = 10110110 and B = 00110111.

(a) Give the decimal equivalent of each number, assuming that (1) they are unsigned and (2) they are signed 2s complement.

(b) Add the two binary numbers and interpret the sum, assuming that the numbers are (1) unsigned and (2) signed 2s complement.

(c) Determine the values of the C (carry), Z (zero), N (sign), and V (overlow) status bits after the additions.

(d) List the conditional branch instructions from Table 9-8 that will have a true condition for each addition.
