Start Sum = 0 More words? [yes] Sum = Sum + Next Word [no] Left(sum) is nonzero? Sum = Left(Sum) + Right(Sum) Iyes] [no] Notes: a. Word and Checksum are each 16 bits, but Sum is 32 bits. b. Left(Sum) can be found by shifting Sum 16 bits to the right. c. Right(Sum) can be found by ANDing Sum with (0000FFFF) 16 d. After Checksum is found, truncate it to 16 bits. Checksum = Complement (Sum) Checksum = truncate (Checksum) Stop
