Abstract

The invention relates to an embedded system for real-time detecting memory, and relative method for real-time detecting memory and picking up the memory cross mistake, wherein said method comprises: starting one real-tie memory detecting proxy mission module, and initializing the memory detection; receiving background user instruction, and setting memory detecting point; then transmitting said user instructions to the real-time memory detecting proxy mission module; and when the trigger conditions are met, adjusting abnormal interruption.

Description

technical field [0001] The invention relates to an embedded system for real-time memory monitoring and a processing method for real-time memory monitoring and catching memory out-of-bounds errors, in particular to a real-time memory monitoring method in an embedded system engineering version. Background technique [0002] Embedded system, that is, a special computer system embedded in the object system, has been widely used and developed today. "Embedded", "specialized" and "computer system" are the three basic elements of embedded systems. Embedded software usually runs in an embedded operating system, and the hardware platform of an embedded system usually uses a dedicated processing chip. Therefore, the development and debugging of embedded systems need to be supported by special hardware or software tools, and a special debugging version needs to be generated by the compiler. In the engineering version of the software used by the user after the development is completed,...
