Question: Assume that you are using a single error correcting, double error detecting (SEC/DED Hamming code: d. What is the minimum number of parity bits required

Assume that you are using a single error correcting, double error

Assume that you are using a single error correcting, double error detecting (SEC/DED Hamming code: d. What is the minimum number of parity bits required to protect a 128-bit word using the SEC/DED code? e. What is the minimum number of parity bits required to protect a 64-bit word using the SEC/DED code? i. Cost is the relative number of parity bits needed while performance is the relative number of errors that can be corrected Calculate the cost/performance ratio of the 128-bit SEC/DEC code versus the 64-bit code. ii. Which is better? f. Consider the SEC code that protects 8 bit words with 4 parity bits. If we read the value 0 times 375, is there an error? If so, correct the error
