An autodiagnostic system known as adaptive integrated microdiagnostics (AIM) integrates test techniques under microcode control so that it can automatically move a microcode break point for the purpose of collecting hardware test data. Break point is the location in a program where a stop is made to transfer control. The host for AIM is a bubble memory unit (BMU), an avionic mass memory which operates under distributed multi-microprocessor control. These microprocessors are arranged such that each has access to the others for testing purposes. AIM is not dependent on the BMU and could be implemented on any processor-controlled host. AIM treats BMU system level autodiagnostics as a two-tier problem, performing card-level, then board level fault detection and isolation.
