A mechanism for continually testing a first processor element in a suitable multiprocessor system in which at least first and second processor elements are connected to a common input bus to concurrently receive the same opcodes and operands. Both processors decode the opcodes; when an opcode indicates an operation to be performed by the second processor, the first processor responds by executing ...

In a data processing system, a memory (32) consists of data words and associated error-correction codes that are independently accessible; it is possible simultaneously to read a data word and write its associated error-correction code. This allows a memory-control circuit (30) immediately to store in the memory (32) a data word sent by a processor (10) while it is concurrently in the process of g...
