In addition, functional units in the embodiments of the present disclosure may be integrated into one processing unit, or each unit may exist alone physically, or two or more units are integrated into one unit.
The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. In the description corresponding to the flowcharts and block diagrams in the figures, operations or steps corresponding to different blocks may also occur in different orders than disclosed in the description, and sometimes there is no specific order between the different operations or steps. For example, two sequential operations or steps may in fact be executed substantially concurrently, or they may sometimes be executed in the reverse order, depending upon the functionality involved. Each block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.

1. A method for obtaining system stack utilization, comprising:
filling a system stack by using preset initial data;
acquiring the number of stack data different from the initial data in the system stack;
and determining the utilization rate of the system stack according to the number.
2. The method of claim 1, wherein obtaining the amount of stack data in the system stack that is not the same as the initial data comprises:
determining a first stack address to be detected corresponding to the system stack, and acquiring stack data corresponding to the first stack address to be detected;
comparing stack data corresponding to the first stack address to be detected with the initial data to obtain a comparison result;
determining a search area according to the comparison result;
and determining the number of stack data which is different from the initial data in the system stack according to the search area.
3. The method of claim 2, wherein determining a search area based on the comparison comprises:
determining the first stack address to be detected as an alternative termination address and acquiring a start address of the system stack under the condition that the comparison result is that stack data corresponding to the first stack address to be detected is the same as the initial data;
and determining a system stack area between the starting address and the alternative terminating address as a search area.
4. The method of claim 2, wherein determining a search area based on the comparison comprises:
determining the first stack address to be detected as an alternative starting address and acquiring the growth direction of the system stack under the condition that the comparison result is that the stack data corresponding to the first stack address to be detected is different from the initial data;
and determining a system stack area in the same direction along the growing direction from the alternative starting address as a search area.
5. The method of claim 4, wherein determining the amount of stack data in the system stack that is not the same as the initial data based on the lookup area comprises:
determining a search stop address from the search area; stack data corresponding to the search stopping address is different from the initial data, and a previous group of stack data of the search stopping address along the same direction as the growth direction is the same as the initial data;
acquiring a data group number of initial data corresponding to the search stop address;
and determining the data group number as the number of stack data which is different from the initial data in the system stack.
6. The method according to any of claims 1 to 5, wherein determining the usage of the system stack based on the number comprises:
acquiring the number of filling groups of the initial data;
and calculating by utilizing the number and the filling group number according to a second preset algorithm to obtain the utilization rate of the system stack.
7. An apparatus for deriving system stack utilization, comprising:
the filling module is configured to fill the system stack with preset initial data;
an obtaining module configured to obtain the number of stack data in the system stack that is different from the initial data;
a determining module configured to determine a usage rate of the system stack according to the number.
8. An apparatus for acquiring system stack usage, comprising a processor and a memory storing program instructions, wherein the processor is configured to perform the method of any of claims 1 to 6 when executing the program instructions.
9. An electronic device comprising means for deriving system stack usage according to claim 8.
10. A storage medium storing program instructions which, when executed, perform the method for deriving system stack usage of any of claims 1 to 6.
