Abstract:
A method is disclosed for detecting a memory stack fault. The method may include reserving a memory stack for executing software instructions. The method may also include enabling a debug unit and as the software instructions are execute, utilizing the debug unit to monitor a memory space adjacent to the memory stack. The method may further include identifying a memory stack fault if a write operation to the memory space is attempted.
