- True/False In Floating Point Addition, the exponents of the two numbers being added need to be made equal before the mantissa fields can be added, as this ensures that the bit positional values are now alignedA 4-bit data word (1101)2 is encoded using Hamming ECC for single error correction. Write the corresponding 7-bit codeword that is stored in memory below. Enter your answer hereASCll code x/y=m odd polarity, leftmost position in 7. bits in hexadecimal are x78, y79, m6D, /2F, =3B
- True/False The number of distinct values represented in a 32-bit sign-magnitude binary representation is identical to the number of numbers represented in a 32 bit 2's complement notation.5 Find the bitwise OR, bitwise AND, and bitwise XOR of each of these pairs of bit strings:a) 11 1111 1111, 00 0000 0000b) 1111 0000, 1010 1010 c) 00 0111 0001, 10 0100 1000If an integer value of 43 is stored in ieee754 double precision format what binary bits are saved in the format (a) 101011 (b) 01011 (c) 1011 (d) 0101011
- The 16 bit signed fixed point representation using 4 bits after decimal point of -2345.125 is given in hexadecimal as: Ox__ (don't display decimal point)1- If the information bits are unchanged in their values, the code can be supposed: Systematic and Nonsystematic codes in the same time O Nonsystematic codes O systematic codes O Could not be decideThe base 10 representation of the largest signed value that can be stored using only 6 bits is: 63 126 31 011111
- Character P is encoded as 1010000 in a computer. Usually, a parity bit will be sent together with a character. What is the odd parity bit for character P?Using an 8-bit floating-point format in which the most significant bit is the sign bit, the next three bits represent the exponent field in excess notation, and the last four bits represent the mantissa, write the bit pattern that represents the value 1 3/4. (Use normalized form.)2. Convert the IEEE 754 single precision binary representation to a decimal number 1001 1001 1011 0000 0000 0000 0000 0000 Note: make sure that in final answer the fraction is in base 10 (at most 3 digits). You don't need to change the power of 2 in a power of 10.
