    摘要： A mechanism is provided for managing hardware breakpoints within a computing environment comprising a processor and a memory unit with addressable words being extended using metadata. A setting or deleting of a breakpoint is issued at a specific address within the memory unit by forwarding from the processor to the memory unit the metadata. An addressable word is requested from the memory unit by forwarding a physical address of the addressable word via an address bus from the processor to the memory unit. The physical address is decoded to find the addressable word within the memory unit. Responsive to the metadata associated with the addressable word being available, the metadata is provided to the processor. A checking is made as to whether a breakpoint is set in the metadata. Responsive to the breakpoint being found in the metadata, an interrupt is triggered thereby executing the breakpoint.
