    摘要: 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.

    摘要: Integrated circuits such as programmable integrated circuits may include calibration circuitry for calibrating memory interface circuitry. The calibration circuitry may include processing circuitry and test circuitry. The processing circuitry may provide instructions to the test circuitry and direct the test circuitry to begin processing at a selected instruction. The test circuitry may retrieve data storage addresses and control signal storage addresses from the instructions. The test circuitry may use the data storage address to retrieve test data from data storage circuitry and may use the control signal storage address to retrieve control signal data from control signal storage circuitry. The control signal, address, and test data may be provided to the memory interface circuitry. The test circuitry may verify data received from the system memory during instruction processing.

    摘要: Systems and methods for increasing speed and reducing area for arbitration logic in an integrated circuit (IC) are provided. For example, in one embodiment, a method includes arbitrating at least one master request in a first level of arbitration blocks. A second level of arbitration blocks arbitrates at least two arbitration blocks from the first level. A first level of multiplexers multiplex at least one master payload based at least in part upon the arbitration of the first level of arbitration blocks. A second level of multiplexers multiplex at least two signals propagated from the first level of multiplexers.
