Abstract: A storage controller, storage device, and host-storage system are provided. The storage controller includes a physical function allocated to a physical machine of a host that processes first data; a first virtual function allocated to a first virtual machine of the host that processes second data; a second virtual function allocated to a second virtual machine of the host that processes third data; a rescheduling unit configured to assign priority tokens to each of the physical function, the first virtual function, and the second virtual function; and a multi-tenant power control unit configured to receive sub-power states of the physical function, the first virtual function, and the second virtual function, and allocate a power budget to each of the physical function, the first virtual function, and the second virtual function based on the assigned priority tokens and the sub-power states.

Abstract: The present invention relates to a safety board system. The safety board system of the present invention is installed on a pedestrian crossing to assist individuals with reduced mobility in safely crossing the pedestrian crossing, the safety board system including: a pair of lift platforms that are formed on sidewalks on both sides of the pedestrian crossing; one or more shuttles that move along a predetermined travel path within a travel area set on the pedestrian crossing to travel back and forth between the pair of lift platforms and transport passengers to the opposite lift platforms; a driving device that moves the shuttles; and a control device that selectively operates the driving device. Therefore, the present invention can directly assist the movement of mobility disadvantaged persons crossing the pedestrian crossing, leading to rapid and safe crossing.

Abstract: A memory controller, a memory system and a method of operating a memory controller controlling a memory device are described. The memory controller may include a workload manager in communication with the memory device in which data is written and is read, the workload manager configured to acquire an amount of write data written to the memory device during a preset reference time, calculate a workload parameter indicating a ratio of the amount of write data to a reference write amount, and store the workload parameter for the preset reference time, and a performance manager configured to control, based on the workload parameter, a certain background operation performed by the memory device during a period corresponding to the workload parameter.
