1. (a) Give means to identify on whether or not has overflow has occurred in 2s complement addition or subtraction operations. Take one example for each possible situation and explain. Assume 4 bit registers. Let If overflow register E is also considered, check whether the result is corrector not [6] (b) Represent -32.75 and 18.125 in single precision IEEE 754 representation. [10]
