ICT 114 Computer Architecture

PLEASE PROVIDE WORKING AND FORMULA

(b) Given X= 5510 and Y = -6610. (1) Express the value of X and the value of Y in 8-bit binary if sign-magnitude representation is used for integers. (2 marks) Express the value of X and the value of Y in 8-bit binary if 2's complement signed integer representation is used. (5 marks) (iii) Find the result of X + Y by performing the computation in 2's complement arithmetic. Convert the result to decimal and show it is equal to -11. (4 marks) The hexadecimal number COFE represents a 16-bit floating point number. Its representation is given in Figure Q1(c). What is the decimal value? Show your working. (c) Bit 15 87 0 8 bits 8 bits Mantissa (M) is an unsigned Exponent (E) is in 2's fixed-point fraction complement Decimal value (0.M)* 2E Figure Q1(c)
