    Abstract: The invention relates to a network processor for managing communication between a central processing unit running tasks on one or more partitions, and a PPA logic circuitry. Management portals pass messages to and from the central processing unit. A management portal communicates with one of the partitions. A resource state manager is arranged to manage resources of the PPA logic circuitry and to communicate states of the resources to the tasks via the management portals. A controller driver drives the PPA logic circuitry using information received from the resource state manager and the instructions from a data interface. The networking device does not need a separate master partition, and is allowing a programmer to deploy the system fast and with minimal risk or effort on different integrated systems.

  • Publication number: 20150277973
    Abstract: A data processing system includes a processor core and a hardware module. The processor core performs tasks on data packets. The hardware module stores a first ordering scope identifier at a first storage location of the ordering scope manager. The first ordering scope identifier indicates a first ordering scope that a first task is operating in. The ordering scope manager increments the first ordering scope identifier to create a new ordering scope identifier. In response to determining that the processor core is authorized to transition the first task from the first ordering scope to a second ordering scope associated with the new ordering scope identifier, the ordering scope manager provides hint information to the processor core. The processor core transitions from the first ordering scope to the second ordering scope without completing a task switch in response to the hint information.

  • Patent number: 9148056
    Abstract: An integrated circuit (IC) with voltage regulation includes high power and low power domains, low and high voltage regulators and a low power regulator. The low voltage regulator powers the high and low power domains when the IC is in a HIGH power mode. The low power regulator receives a voltage from a high voltage regulator and powers the low power domain when the IC is in a LOW power mode. The IC includes a switching module that disconnects the low voltage regulator from the low power domain when the output voltage of the high voltage regulator is lower than a threshold voltage during power-up and connects the low voltage regulator to the low power domain when the voltage regulated by the high voltage regulator exceeds the threshold voltage.

  • Patent number: 9145104
    Abstract: An airbag apparatus connected with a battery includes activation circuits each of which has a squib and a high-side switching element, a safing switching element connected between the battery and the activation circuits, a safing switch control circuit controlling the safing switching element to provide a target voltage to the activation circuits, a terminal voltage acquiring circuit that acquires a terminal voltage of each squib, and a target voltage setting circuit that sets the target voltage. When a maximum-terminal voltage is lower than a reference voltage, the target voltage setting circuit sets the target voltage to be equal to the reference voltage. When the maximum-terminal voltage is higher than the reference voltage, the target voltage setting circuit sets the target voltage to correspond to the maximum-terminal voltage so that a reverse current is avoided in the high-side switching element.
