Abstract
An address monitor device includes a boundary address register, a stack pointer register, and a comparator. The boundary address register is configured to monitor a boundary address of a stack based on a usage state of a stack pointer. The stack pointer register is configured to obtain a usage address of the stack at present based on the usage state of the stack pointer. The comparator is configured to compare the stack pointer and the boundary address for determining whether to output an interrupt command.
Claims20
An address monitor device, comprising:
- a boundary address register, configured to monitor a boundary address of a stack based on a usage state of a stack pointer;
- a stack pointer register, configured to obtain a usage address of the stack at present based on the usage state of the stack pointer;
- and
- a comparator, configured to compare the stack pointer and the boundary address for determining whether to output an interrupt command.
