  • Patent number: 11954527
    Abstract: A resource allocation method comprises using resources with a used resource quantity of a machine learning system to execute a first experiment which has a first minimum resource demand, receiving an experiment request associated with a target dataset, deciding a second experiment according to the target dataset, deciding a second minimum resource demand of the second experiment, allocating resources with a quantity equal to the second minimum resource demand for an execution of the second experiment when a total resource quantity of the machine learning system meets a sum of the first minimum resource demand and the second minimum resource demand and a difference between the total resource quantity and the used resource quantity meets the second minimum resource demand, determining that the machine learning system has an idle resource, and selectively allocating said the idle resource for at least one of the first experiment and the second experiment.

  • Patent number: 8148971
    Abstract: A layout of a voltage/current reference system is disclosed. A first voltage/current reference circuit (for example, a bandgap reference circuit) and a second voltage/current reference circuit are respectively laid out on either side of a substrate, such as edges or perimeter sides of the substrate. A reference voltage/current is derived by averaging respective output reference voltage/current values of the first and the second voltage/current reference circuits. Accordingly, the noise influence on the voltage/current reference system is minimized.

  • Patent number: 7952229
    Abstract: A power distribution system is disclosed. The system includes a first power line and a second power line laid out on a substrate. The first power line is spaced apart from the second power line. The system also includes at least one conductive connecting line that electrically couples the first power line at one end and the second power line at another end. A power supply supplies power to the first power line and the second power line. A supply node on the conductive connecting line is then used to provide the supplied power.
