2. (a) Work out the multi-level carry lookahead scheme for doing a 32-bit number addition by 2 methods: (i) (ii) 8 numbers of 4-bit carry lookahead adders. 4 numbers of 8-bit carry lookahead adders. How many gate delays are required to do the complete addition in each of the above 2 methods? (b) Consider the use of the Hamming code to send this 8-bit message (00111101). (i) Determine the Hamming code word for this message. (ii) Suppose data bit 6 in the above question sustains an error and is changed from 1 to 0. Determine the syndrome and hence show that the Hamming code will identify the error.
