Abstract of the Disclosure A microprogrammed control unit of an information processing system having a control sequencer with dual microprogram counters for performing microdiagnostics simultaneously with performing macroprograms. The micro- diagnostics comprise background and operability tests, the background tests being interleaved with macroinstruction operations under the control of the two independent micro- program counters. The background tests are run during processor idle time and the operability tests are executed at processor or turn-on. The organization of the micro- diagnostics into a hierarchical structure allows the use of the same microprogrammed test module for both the background and operability microdiagnostic tests. A prediction/residual coding technique provides fault detection for address and data information within the control sequencer.
