ABSTRACT:
A system for error correction in the reading and writing of data to memory in a multiprocessor environment such as a parallel processor. The data written to and read from memory for each processor is channeled through a single error correcting system which effectively treats the data for plural memories associated with plural processors as a single data word and generates a single error correcting code for that combined data word. By applying a single error correcting methodology to a plurality of memories and associated processors, far greater efficiency is achieved in the parallel processor environment. The read and write operations for the plural memories must be accomplished substantially simultaneously in order that the read and write operations can be treated as acting on a single word and a single error correcting code generated. This ideally suits the system for use in parallel processor environments where the processing function is distributed over a multiplicity of processors and associated memories, acting in parallel.
