ABSTRACT:
A data processing system is composed of three data processing modules each of which comprises mutually corresponding processing means. The results are applied to all other data processing modules via an interconnection network. For the interconnection an encoder is connected in at least two data processing modules. Encoding envolves the multiplication of the multi-bit quantities received by respective, regular matrices which differ from the identity matrix as well as from one another. By a suitable choice of these matrices, one code symbol or two bit errors in different code symbols can be corrected for a width of 4 bits. In an erasure mode one further bit error is correctable outside the ignored symbol. For larger values of k, the maximum error protection capability can be increased further.
