Abstract

A method and a device for reconstructing the sequence of processes of a control program executed by a computing device, in particular a microprocessor, from the contents of a first table and a second table. The control program is subdivided into a plurality of tasks, and each task has at least one process. During execution of the control program, for each completed task, an identifier for a process last executed before the start of the completed task is stored in the first table. The order of the respective completed tasks is stored in the second table. To reliably reconstruct the process sequence, the method and device involve the following. At first, from the contents of the first table and the second table, a third table is generated which contains, for each new task, the identifier for a process last executed before the start of the new task, and the complete process sequence of the control program is then reconstructed from the third table with the knowledge of the process sequence of the individual tasks.
