Abstract
In a code generation device for generating a code: a binary-data generation circuit generates first binary data items indicating every (m+1)th one of n successive binary numbers, where m≧1 and n≧2. A binary-data derivation circuit derives m+1 second binary data items indicating m+1 binary numbers from each of the first binary data items, where the m+1 binary numbers include the first binary data item. A first processing circuit performs a predetermined common operation on identical portions of the m+1 second binary data items, and a second processing circuit performs individually predetermined operations on non-identical portions of the m+1 second binary data items, where states of corresponding bits in the non-identical portions of the m+1 second binary data items are not identical. A combining circuit combines the outputs of the first and second processing circuits.
