  • Patent number: 11042321
    Abstract: A memory controller that controls a nonvolatile memory in response to commands from a host, includes a normal transfer queue and a priority transfer queue, a transfer packet priority determination unit, a transfer queue selector, and a transfer packet selector. The transfer packet priority determination unit determines whether a transfer packet is a priority packet based on transmission information of the transfer packet. The transfer queue selector selects the priority transfer queue and stores the transfer packet in the priority transfer queue when the transfer packet is determined as the priority packet, and selects the normal transfer queue and stores the transfer packet in the normal transfer queue when the transfer packet is not determined as the priority packet. The transfer packet selector transfers to a host a priority packet stored in the priority transfer queue preferentially with respect to a normal packet stored in the normal transfer queue.

  • Patent number: 10513999
    Abstract: An engine controller according to one aspect of the invention is applied to a cylinder injection engine including a fuel injection valve that directly injects fuel into a cylinder. The engine controller determines whether knocking is occurring based on a signal from a knocking sensor. When the knocking is occurring, the engine controller performs partial lift fuel injection at a predetermined timing close to an ignition timing. The partial lift fuel injection is performed with a lift amount of a valve body of the fuel injection valve limited within a range between a minimum lift amount (0) and a partial lift amount, which is smaller than a maximum lift amount.
