Abstract: A boost power conversion circuit includes an inductor, a first switch module, a second switch module, a first unilateral conduction component, a second unilateral conduction component, a flying capacitor, an upper bus capacitor, a lower bus capacitor, and a third unilateral conduction component. The power supply, the inductor, the first switch module, and the second switch module are connected in series to form a loop. The first unilateral conduction component, the second unilateral conduction component, the upper bus capacitor and the lower bus capacitor are connected in series. The flying capacitor is electrically connected between a reverse cut-off end of the first unilateral conduction component and a forward conduction end of the second unilateral conduction component. The third unilateral conduction component is configured to clamp a voltage stress of the second switch module to a lower-bus voltage.

Abstract: The present disclosure relates to a call collision processing method for a terminal device, and a terminal device. A state machine records that a current state of the terminal device is an incoming call state, an outgoing call state, or an idle state. When the terminal device is in the idle state, that the terminal device processes an incoming call or an outgoing call is determined according to occupation of the state machine by incoming call information or by outgoing call information, and a state of the state machine after the state machine is occupied by the incoming call or the outgoing call is protected by using a mutex lock.

Abstract: This application provides a service processing method and apparatus, a terminal device, and a chip, and relates to the field of communication technologies. When the terminal device carries a primary card and a secondary card, the secondary card uses one or more antennas by default to process an uplink/downlink transmission service. When the primary card is triggered to perform neighboring cell measurement (e.g., inter-frequency inter-RAT measurement), and a measurement band is the same as an operating band of the secondary card, the primary card may select an antenna different from an antenna used by the secondary card to perform neighboring cell measurement.

Abstract: Embodiments of this application disclose a channel arbitration method and an apparatus. After receiving an uplink grant for a first SIM card, a physical layer scheduler of a terminal device configures a transmission service priority of the first SIM card in a front-end arbiter as a first predicted priority, and configures PUSCH transmission information for the front-end arbiter based on the uplink grant, where if packeting for uplink scheduling is completed before an arbitration time point, the transmission service priority of the first SIM card is updated to a service priority of a MAC layer; the front-end arbiter arbitrates a transmission service of the first SIM card based on the PUSCH transmission information and the transmission service priority; and further, if the first SIM card is performing a voice service and the arbitration continuously fails, fallback to a DSDS 2.0 mode is triggered.

Abstract: A display method of a terminal device and a terminal device is provided. The display method of a terminal device includes: a framework layer sends a first touch point data; an application layer sends instruction information used to instruct to transfer slide drawing control rights to the framework layer and a generated display list to the framework layer after the application layer determines that the terminal device enters a sliding state according to acquired first touch point data; and the framework layer acquires second touch point data from a shared memory according to the instruction information, and draws an image according to the second touch point data and the display list. In this way, in an operation with repetitive image composition, the slide drawing control rights are transferred from an application module to a framework module, improving a response speed of a terminal system.

Abstract: Embodiments of the present invention disclose a CDR circuit and a terminal, where the CDR circuit is configured to perform clock synchronization in a terminal with EEE function, and the CDR circuit includes: a phase detector, a first phase signal selector, a loop filter, a numerical controlled oscillator, a second phase signal selector, a phase signal generator, and a state machine. In the embodiments of the present invention, after the terminal enters a REFRESH state from a QUIET state, the CDR circuit can implement clock synchronization with a peer end without waiting for the loop filter and the numerical controlled oscillator to be converged, but the phase signal generator generates a phase signal satisfying a preset clock synchronization condition, and the second phase signal selector selects the phase signal satisfying the preset clock synchronization condition as the phase selection signal of the CDR.
