  • System and method for testing for memory address aliasing errors
    Patent number: 7523291
    Abstract: Aliasing errors, occasioned by, for example, a programming error resulting in including extra or missing bits in a storage address, wrong addressing mode, or wrong address context, are detected by providing a storage address configuration including gaps in valid addresses. Such a programming error is detected and an exception is thrown (that is, an addressing error is detected and indicated) responsive to an address reference to such a gap in valid addresses. Gaps are configured at complementary address ranges to facilitate detection of such aliasing errors.
