Abstract
A built-in self-test (BIST) diagnostic system tests the execution of a processor. The processor is arranged to execute a normal application for controlling a process that is external to the processor. The normal execution is executed in normal execution timeslots that have idle timeslots that are interspersed in time between the normal execution timeslots. A BIST controller is arranged to detect the presence of an idle timeslot in the execution of the processor and to use a scan chain to scan-in a first test pattern for a test application for testing the processor. The first test pattern is executed by the processor during the detected idle timeslot and a first result pattern generated by the execution of the first test pattern is scanned-out. The scanned-out first test pattern is evaluated to determine the presence of an error. The first test pattern application is conditionally interruptible.
