Q31.
Two eight bit bytes 11000011 and 01001100 are added. What are the values of the overflow, carry and zero flags respectively, if the arithmetic unit of the CPU uses 2's complement form?Q32.
Consider the following representation of a number in IEEE 754 single-precision floating point format with a bias of 127. S:1E:10000001F:11110000000000000000000 Here, S,E and F denote the sign, exponent, and fraction components of the floating point representation. The decimal value corresponding to the above representation (rounded to 2 decimal places) is ____________.Q33.
