Abstract
A system and method of stopping program execution includes tagging an entry in a virtual cache with an indicator bit where the virtual address of the entry corresponds to a virtual address range in a break point register, in response to a second virtual cache data access demand matching the entry tagged with the indicator bit, determining whether the second data access demand matches the virtual address range of the breakpoint register, and in response to the second data access demand matching the virtual address range of the break point register, flagging an exception and stopping execution of the program. In an embodiment, the method or system enters a slow-mode in response to the second data access demand matching the virtual cache entry with the indicator bit, and performs a full comparison between the second data access demand and the break point register virtual address range.
