System and method for monitoring and managing processor-internal memmories of a process-executing unit

Abstract

A system and a method for managing and monitoring processor-internal memories of a process-executing unit or program unit, having a global stack memory area (1) for executing processes and sub-processes of a program sequence comprising different sub-processes, and a monitoring unit (2) for protecting and monitoring the address space of the stack memory area (1) between an upper limit (UL) and a lower limit (LL). The monitoring unit (2) has a separate, internal stack (3), which is adapted for storing a variable logical limit, e.g., the lower limit (LL), of the global stack memory (1) on each level of a nested arrangement of the program sequence in the transition between different processes. Data of a preceding process located on the other side of a stored variable logical limit, e.g., of a current process, are protected.

Dependencies are inferred from the claim text.
