  • Patent number: 8918748
    Abstract: A method for performing latency optimization on a system design to be implemented on a target device includes inserting a variable latency indicator in the system design at a place where latency can be varied. The system design includes pipeline registers at the place where the variable latency indicator is inserted. Latency optimization is then automatically performed on the system design, during a computer aided design flow performed by an electronic Design Automation (EDA) tool, by varying the number of the pipeline registers at the variable latency indicator to obtain optimized latency without affecting system performance of the system design.

  • Patent number: 8897083
    Abstract: An integrated circuit may include memory interface circuitry for communicating with off-chip memory. The memory interface circuitry may receive data signals and data strobe signals from different memory devices via respective data ports and data strobe ports. The memory interface circuitry may be operable in at least first and second modes. In the first mode, data signals from each memory device may be received at two respective data ports while the data strobe signal from one memory device is used to clock the data signals at two corresponding read capture registers. In the second mode, data signals from first and second memory devices may be received via first and second data ports, respectively. The data strobe signal from the first memory device may be ignored while the data strobe signal from the second memory device is used to clock the data signals at two corresponding read capture registers.

  • Patent number: 8813018
    Abstract: A logic design system operable to configure an integrated circuit device using custom logic design data is disclosed. The disclosed logic design system includes a computer-aided design tool that may be used to determine a memory space estimate based on a custom logic design data analysis. A memory size analysis may be performed on the custom logic design data to determine the maximum amount of stack memory that is required to execute procedures in the device. The logic design system may also monitor for changing memory requirements of the custom logic design. The logic design system may configure the device with the custom logic design data based on the memory space estimate.

  • Patent number: 8499201
    Abstract: Mechanisms for measuring, analyzing, and presenting performance data associated with a memory controller system are described. The mechanisms include a performance monitor that detects and analyzes performance including efficiency and latency of a memory controller system. In addition to determining performance, the systems identifies reasons for loss of memory controller system efficiency. Moreover, the reasons, the efficiency, and the latency are analyzed and presented in a manner easily understandable to a user.

  • Publication number: 20120260032
    Abstract: Systems and methods for using memory commands are described. The systems include a memory controller. The memory controller receives a plurality of user transactions. The memory controller converts each user transaction into one or more row and column memory commands. The memory controller reorders the memory commands associated with the plurality of user transactions before sending the memory commands to a memory device.
