Processing system with stack management and method for stack management
摘要
The invention provides a processing system, comprising a memory comprising a processor call stack; a stack space usage register configured to determine the stack space usage of the processor call stack and to store a usage parameter indicative of the determined stack space usage; a first threshold register configured to store a pre-determinable first stack level threshold; and a first comparator configured to compare the usage parameter with the first stack level threshold and to output a first interrupt blocking signal, if the usage parameter exceeds the first stack level threshold, the first interrupt blocking signal being configured to block the decoding of interrupt signals input to the processing system and having interrupt priorities lower than or equal to or just lower than a first interrupt priority threshold. The invention further provides a method for stack management, especially in a processing system.
