  • Scheme for implementing breakpoints for on-chip ROM code patching
    Patent number: 6925521
    Abstract: The present invention relates to a system and a method for preventing address conflicts when establishing breakpoints and applying one or more patches to code residing on a read only memory (ROM) device. The system and method generally comprises identifying one or more program addresses which require patching, whereby one or more patch addresses are defined; evaluating address bits of the patch addresses and determining index bit positions, whereby address bits occupying the index bit positions define one or more unique tag indices; and storing the index bit positions in a tag programming memory.
