  • Method for verifying that a processor is executing instructions in a proper endian mode when the endian mode is changed dynamically
    Patent number: 6279126
    Abstract: A method verifies that a processor is executing instructions in a proper endian mode when the endian mode is changed dynamically. In accordance with the present invention, a test suite written and compiled in big endian mode is loaded into memory. The test suite is converted to little endian mode and stored back to memory. Next, the processor status is changed from big endian mode to little endian mode, and the test suite is executed. Finally, the results of the test suite are examined to ensure that the processor properly executed the instructions in little endian mode.
