  • System and method for calculating a checksum address while maintaining error correction information
    Patent number: 8370705
    Abstract: One or more embodiments of the invention set forth techniques to perform integer division using addition operations in order to provide address translation capabilities to a processor. The processor supports a memory that maintains checksum information such that address requests received by the processor need to be translated to a checksum address and an actual data address that accounts for use of portions of the memory to store checksum information. Once the checksum address and the actual data address are computed, the processor can confirm the integrity of the data stored in the actual data address and correct any errors if need be, based on the checksum information stored in the checksum address.

  • Memory-based error recovery
    Patent number: 8365015
    Abstract: The present disclosure provides memory level error correction methods and apparatus. A memory controller is intermediate the memory devices, such as DRAM chips or memory modules, and a processor, such a graphics processor or a main processor. The memory controller can provide error correction. In an example, the memory controller includes a buffer to store instructions and data for execution by the controller and a replay buffer to store the instructions such that operations can be replayed to prior state before the error. An error detector receives data read from the memory devices and if no error is detected outputs the data. If an error is detected, the error detector signals the memory controller to replay the instructions stored in the replay buffer.

  • Probe monitoring system for riverbed elevation monitoring at bridge piers
    Patent number: 8352213
    Abstract: A probe monitoring system for riverbed elevation monitoring at bridge piers is revealed. The system includes a housing, a measuring rod, a moving member, a control module, a photographic unit and a sensing unit. The housing is fixed on the pier. Both the moving member for driving the measuring rod and the control module for control of the moving member are mounted in the housing. When the control module drives the measuring rod to move downward and the sensing unit on the bottom of the measuring rod approaches the riverbed, a sensing signal is sent to the control module. Thus the moving member stops moving the measuring rod and the photographic unit takes pictures of the measuring rod to generate an image. Then the riverbed elevation is obtained according to the image or the movement of the moving member and is sent to a remote monitor unit for real-time monitoring.
