  • Patent number: 11656675
    Abstract: A method of operating an application processor including a central processing unit (CPU) with at least one core and a memory interface includes measuring, during a first period, a core active cycle of a period in which the at least one core performs an operation to execute instructions and a core idle cycle of a period in which the at least one core is in an idle state, generating information about a memory access stall cycle of a period in which the at least one core accesses the memory interface in the core active cycle, correcting the core active cycle using the information about the memory access stall cycle to calculate a load on the at least one core using the corrected core active cycle, and performing a DVFS operation on the at least one core using the calculated load on the at least one core.

  • Patent number: 11271897
    Abstract: An electronic apparatus includes a first translation table that stores information of a first address and a second address; a second translation table that, in response to a condition being satisfied, stores the information of the first address and the second address based on the first translation table; at least one processor configured to translate the first address of a first packet to the second address based on the first translation table; and a forwarding manager that, in response to a second packet including the first address being received and the information of the first address and the second address being stored in the second translation table, translates the first address of the second packet to the second address based on the second translation table, prior to allocating the second packet to the at least one processor.

  • Patent number: 9880608
    Abstract: An application processor includes a central processing unit (CPU), intellectual properties (IPs), a hardware power management unit (PMU) configured to determine whether the application processor is in system idle based on a first idle signal output from the CPU and output control signals as a result of the determination, and a clock signal supply control circuit configured to change an output signal supplied to the CPU and the IPs from clock signals to an oscillation clock signal, based on the control signals. The oscillation clock signal has a frequency lower than that of the clock signals.
