Abstract: A semiconductor chip includes a hardware performance monitor (HPM) unit and an HPM controller. The HPM unit is driven during an initial operation period, a first operation period, and a second operation period, outputs initial HPM data, first HPM data, and second HPM data in the initial operation period, the first operation period, and the second operation period, respectively. The HPM controller performs a first compensation operation of compensating a driving voltage of the semiconductor chip using the initial HPM data and the first HPM data, and a second compensation operation of compensating the driving voltage using the initial HPM data and the second HPM data. The HPM unit provides the initial HPM data, the first HPM data, and the second HPM data, which are correlated with performance of the semiconductor chip, to the HPM controller in a first mode, and does not provide this data in a second mode.

Abstract: A system for creating a service account includes a first server associated with a first application, a second server associated with a second application, and an electronic device that is capable of communicating with the first server and the second server. The electronic device is configured to receive user information by executing the first application and verify or generate a first account corresponding to the first application through interaction with the first server, based on the user information. The electronic device is also configured to generate a second account corresponding to the second application through interaction with the second server, based on at least a portion of the user information if the second application is executed in response to a specified event.
