Abstract: A method of controlling discard operations is performed in a system that includes a host device and a data storage device. The method includes providing a shared discard bitmap accessed commonly by the host device and data storage device. The shared discard bitmap includes discard bits in one-to-one correspondence with target sectors of a nonvolatile memory device in the data storage device. The method also includes setting bit values of the discard bits stored in the shared discard bitmap, the bit values indicating whether data stored in each of the target sectors are discardable. An asynchronous discard operation may then be performed with respect to the target sectors based on the bit values of the discard bits stored in the shared discard bitmap.

Abstract: A shift control method can be used for a vehicle with a dual-clutch transmission (DCT). A controller determines whether or not a power-on upshift is initiated in a state in which a high performance mode has been selected. The controller performs a torque phase in which a coupling-side clutch torque is gradually increased and a release-side clutch torque is gradually released. The coupling-side clutch torque is gradually increased to a target coupling-side clutch torque corresponding to a value obtained by adding a push feel torque to a base torque. The controller performs an inertia phase in which the coupling-side clutch torque is gradually increased while tracing an engine torque such that an engine speed is synchronized with a coupling-side clutch speed. The controller completes speed change through gradual decrease of the coupling-side clutch torque.
