ABSTRACT:
A specialized circuit set is included in a data processing system wherein the circuit set registers can be configured into a serial array. A clock signal distribution system delivers controlled clock signals to selected serial arrays. A maintenance data processor provides predetermined signal groups and addressing apparatus responsive to the predetermined signal groups loads and unloads register arrays in response to the predetermined signals. A predetermined signal group is entered into the serial register array, a predetermined number of clock cycles are applied, and the resulting signals shifted from the serial register array are applied to the maintenance data processor for display or analysis. By comparing the expected result for a given initial state with the actual result of an operation sequence, the accuracy of the operation of the data processing system, or any portion thereof, is thereby determined.
