ABSTRACT:
An encoding circuit (10) receives data by way of a bus (12) and stores it in one of two read/write memories (22 and 24). An error-correction-code generator (50) generates codes from groups of the stored words, the members of each group being selected in a complicated fashion. In order to supply the words of the groups to the error-correction-code generator (50) in the proper sequence, a read-only memory (40) contains in successively addressed locations the addresses of the words in the intended sequence. The storage of the address sequence in the read-only memory (40) enables the error-correction coding to be generated in real time with a minimum of complicated addressing hardware.
