The program in a computer compares two signed 2s complement numbers A and B by performing subtraction

Question:

The program in a computer compares two signed 2s complement numbers A and B by performing subtraction A - B and updating the status bits. For operands let A = 11011010 and B = 01110110,

(a) Evaluate the difference and interpret the binary result.

(b) Determine the value of status bits N (sign), Z (zero), and V (overflow).

(c) List the conditional branch instructions from Table 9-10 that will have a true condition.
