Final answer:
The ECC Generator at the I/O Controller generates a 13-bit Vector from the 8-bit Data Vector.
Step-by-step explanation:
ECC (Error Correction Code) is a technique used to detect and correct errors in data transmission. In this case, the ECC Generator at the I/O Controller is responsible for generating the 13-bit Vector from the 8-bit Data Vector. The ECC Generator combines the 8-bit Data Vector with additional parity bits to form the 13-bit Vector.
