Method and apparatus for providing breakpoints on a selectable address range

摘要

A method and apparatus for providing breakpoints on a selectable address range. The apparatus generally includes a processor including a first storage area, a second storage area, a circuit and an execution unit. The first storage area has stored therein a first address, while the second storage area has stored therein a mask. The first address and the mask define an address range. In response to receiving a second address, the circuit accesses the first address stored in the first storage area and the mask stored in the second storage area. The circuit transmits a signal to cause a debug event if the second address is within the address range defined by the first address and the mask.
