ABSTRACT:
A data processing system includes a plurality of units coupled to transfer information over a common bus having an address portion and a data portion. The use of parity bits is made unnecessary by use of both the address and data portion to essentially transfer the same information during a two cycle operation wherein information is transferred from one unit to the other and in response thereto information is transferred back to the first unit. Such information transferred by the first unit over the data portion is effectively returned by the receiving unit over the address portion. Such first unit includes logic for determining whether or not the transferred information is effectively the same as that received from the other unit.
