Abstract: Provided are a Peripheral Component Interconnect Express (PCIe) device and a method of operating the same. The PCIe device may include a performance analyzer, a delay time information generato and a command fetcher. The performance analyzer may measure throughputs of a plurality of functions, and generate throughput analysis information indicating a comparison result between the throughputs of the plurality of functions and throughput limits corresponding to the plurality of functions. The delay time information generator may generate a delay time for delaying a command fetch operation for each of the plurality of functions based on the throughput analysis information. The command fetcher may fetch a target command from a host based on a delay time of a function corresponding to the target command.

Abstract: A foldable device includes: a flexible display configured to display an execution screen of an application; and a controller configured to control the flexible display to display an execution screen of at least one first application on a first surface of the flexible display that is used as a display of the foldable device when the flexible display is folded, and control, in response to the flexible display being unfolded, the flexible display to display the execution screen of the at least one first application and an execution screen of at least one second application related to the at least one first application to be displayed on a second surface of the flexible display that is used as a display of the foldable device when the flexible display is unfolded.

Abstract: A method of measuring a 3D shape, which can measure a 3D shape of target objects on a board by searching a database for bare board information when a measuring object is not set to a normal inspection mode or by performing bare board teaching when the board is supplied from a supplier having not the bare board information is provided.

Abstract: A method of measuring a 3D shape includes the steps of measuring a brightness of a first illumination source 41a, measuring a phase-to-height conversion factor, measuring a 3D shape of a circuit board 62 according to the normal inspection mode, and determining whether bare board information about the circuit board 62 is included. If the information is not included, performing bare board teaching to acquire the information. Then, the 3D shape of target objects on the circuit board 62 are measured, when the bare board information is included or bare board teaching information is generated. Next, the circuit board 62 is analyzed to determine if it is normal or abnormal by using 3D shape information.
