e,f,g,h,i

1) Given: X 0xA4 and Y 0x95, a) Convert X and Y to 8-bit binary numbers. b) Compute the 8-bit sum X+Y of X and Y o) Compute Y the 8-bit two's complement of Y. d) Compute the 8-bit difference X"Y of X and Y. (Use two's complement addition.) o) Convert XiY, Y, and, X Y to hexadecimal. D What are the values of the condition flags z n c v upon computing X-+Y? g) What are the values of the condition flags z n c v upon computing X-y? h) TorF The unsigned 8-bit sum x Y is honest. i) TorF The signed 8-bit sum X+Y is honest. j TorF The unsigned 8-bit difference XY is honest. k) TorF The signed 8-bit difference X"Y is honest.
