Patent number: 10992132Abstract: A power control system provides multiple supply voltages that are guaranteed not to violate boundary conditions regardless of the timing of voltage change commands. A first voltage (Vlogic in the embodiments described herein) is controlled conventionally, and a second voltage (Vmemory) is either selected or generated by adding a selected offset to the first voltage. Both the size of the offset, and the absolute value of the second voltage, are constrained at all times, by constraint values specific to the current voltage zone. The invention ensures a smooth transition between different voltage operating points, and ensures that the trajectory of change between specified operating points remains within predefined boundaries.Type: GrantFiled: July 18, 2019Date of Patent: April 27, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Joni Jäntti, Cecilia Andersson, Bengt Edholm, Masao Naruse, Harri Nissi, Marko Pessa, Mikko Pulkkinen

Patent number: 10070390Abstract: A power management method of a wireless communication device is disclosed. The wireless communication device comprises a modem for wireless communication and a battery for supplying power to the modem. The method comprises obtaining information regarding a power consumption of the modem as a function of time (the information being provided by the modem during wireless communication), forming power consumption statistics from the obtained information (wherein the power consumption statistics comprise an average power consumption during wireless communication as a function of one or more time parameters), and controlling use of the modem by one or more applications of the wireless communication device based on the power consumption statistics. Corresponding computer program product, arrangement and wireless communication device are also disclosed.Type: GrantFiled: October 24, 2014Date of Patent: September 4, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Bhavinkumar Patel, Masao Naruse

Publication number: 20020019898Abstract: It is possible to provide a data-processing system wherein a single device such as a microprocessor is capable of selectively making an access to one of high-speed and low-speed devices each operating synchronously with a clock signal peculiar to the device, and clock control can be executed with ease in an operation to switch the external device to be accessed from one to another. Clock signals each having a required frequency are provided individually through separate clock wires to high-speed and low-speed devices to be accessed by a microprocessor. Since control is executed to switch a synchronous clock signal of an external bus interface control circuit embedded in the microprocessor in accordance with an external device or an address area being accessed by the microprocessor, there is exhibited an effect of easy clock control in an operation to switch the external device to be accessed from one to another without the need to switch the clock signal itself which is to be supplied to the external device.Type: ApplicationFiled: July 5, 2001Publication date: February 14, 2002Applicant: Hitachi, Ltd.Inventors: Isamu Hayashi, Masao Naruse
