  • Publication number: 20240143060
    Abstract: Systems, methods, and circuitries are disclosed generating a dynamic clock signal having a dynamic clock signal frequency for a data processing system from an input clock signal having an input clock signal frequency. In one example, adaptive frequency scaling circuitry includes scaling control circuitry and clock gating circuitry. The scaling control circuitry includes hardware configured to receive a performance indicator value indicative of an operating parameter of the data processing system and select a dynamic clock gating control value based at least on the performance indicator value. The clock gating circuitry is configured to receive the dynamic clock gating control value, and in response, selectively gate the input clock signal based on the dynamic clock gating control value to generate the dynamic clock signal.

  • Publication number: 20240081418
    Abstract: A liquid injection device includes: an accommodating cavity for detachable mounting of an electronic vaporization device; a liquid storage tank; a liquid supply mechanism; and a control assembly. The control assembly is connected to the liquid supply mechanism and detects whether the electronic vaporization device is mounted in the accommodating cavity. The liquid supply mechanism is in communication with the liquid storage tank to: be connected to the electronic vaporization device and supply liquid to the electronic vaporization device when the electronic vaporization device is mounted in the accommodating cavity, and be disconnected from the electronic vaporization device and stop supplying liquid to the electronic vaporization device when the electronic vaporization device is removed from the accommodating cavity.

  • Patent number: 9239787
    Abstract: A system includes an internal memory configured to store data, a memory access controller, logic, and a processor. The memory access controller is operable to read data from a peripheral device in response to an event external to the system, write the data to memory external to the system and forward the data or a portion of the data to the internal memory. The logic is operable to track which portion of the data is stored in both the external memory and the internal memory. The processor has one or more caches logically and physically separated from the internal memory. The processor is operable to retrieve the data forwarded to the internal memory and use the retrieved data to begin servicing the event.

  • Patent number: 8588244
    Abstract: An Ethernet switch has at least one ingress/egress port which is operable in two modes, in a first mode as a GE port and in a second mode as a plurality of FE ports. The port has 8 MAC interfaces each of which is capable of receiving/transmitting FE packets, and at least one of the MAC interfaces can be configured to receive/transmit GE packets. Thus, the port has two modes of operation. The port further includes receive and transmit modules which receive GE and FE packets from, and transmit GE and FE packets to, the interfaces.

  • Patent number: 8463954
    Abstract: Data is processed in an embedded system by writing data read from a peripheral device in response to an event to memory external to the embedded system. The data or a portion of the data is copied to memory internal to the embedded system. Which portion of the data is stored in both the external memory and the internal memory is tracked. The copied data is retrieved from the internal memory by a processor included in the embedded system. The processor has one or more caches logically and physically separated from the internal memory. The processor uses the copied data it retrieved to begin servicing the event.

  • Patent number: 8064471
    Abstract: An Ethernet switch has at least one ingress/egress port 1 which is operable in two modes, in a first mode as a GE port and in a second mode as a plurality of FE ports. The port has 8 MAC interfaces 3 each of which is capable of receiving/transmitting FE packets, and at least one of the MAC interfaces can be configured to receive/transmit GE packets. Thus, the port has two modes of operation. The port further includes receive and transmit modules 5, 7 which receive GE and FE packets from, and transmit GE and FE packets to, the interfaces. If there are 8 such ports in the Ethernet switch, then by switching different numbers of the ports between the two modes, the switch may operate in 9 different modes: as 8 GE ports, 7 GE ports and 8 FE ports, 2 GE ports and 48 FE ports, 1 GE port and 56 FE ports, or simply as 64 FE ports.
