- Using the SEC-DED Hamming code given in class (for 4 bit words), determine whether there is no error, an error in one bit, or an error in two bits for the following 8 bit word fetched from memory. If there is an error in one bit, indicate which bit is in error. 0011 1011arrow_forwardPlease give me correct solution.arrow_forwardDoes the Hamming code follow a particular pattern? Explainarrow_forward
- 2. Assume we are using the simple model for floating-point representation as given in this book (the representation uses a 16-bit format, 5 bits for the exponent with a bias of excess-15, a normalized mantissa of 10 bits, and a single sign bit for the number): Show how the computer would represent the numbers a) +3.53125 and -3.34375 using this floating-point format. a) +3.53125 b)-0.09375arrow_forward1 a. If the last operation performed on a computer with an 8-bit word was an addition in which the two operands were 00000010 and 00000011, what would be the value of the following flags? ● Carry • Zero • Overflow Sign • Even Parity ● Half-Carry b. Repeat for the addition of -1 (twos complement) and +1.arrow_forwardPerform the arithmetic operation (+13) + (-6) and (-13) - (-6) in the signed numbers?arrow_forward
- H - For the IEEE 754 single-precision floating point, write the hexadecimal representation for the following decimal values: (i)–1.0 (ii)– 0.0 (iii)256.015625arrow_forwardUsing bitwise operators, what would be the best way to multiply/divide 208 and 416.Show your steps clearly to receive credit. Also, express your solution in C logic. You donot need to write the whole code. you may utilize addition and subtractionoperations. However, majority of the computations must be done using bitwise operations.arrow_forwarddigital logic . please solve the parts A, B and Carrow_forward
