A storage device comprises a first non-volatile memory, a storage controller configured to receive a memory command for writing data in the first non-volatile memory or reading the data from the first non-volatile memory from a processor of a host device through a first channel, a microcontroller configured to receive a command related to a firmware update executed in the storage device from a baseboard management controller (BMC) of the host device through a second channel different from the first channel, and a second non-volatile memory configured to receive and store firmware data from the BMC of the host device.

Storage device and host device

A method of operating a CPU including a memory for storing a load tracker and a booster and a core for executing the load tracker and the booster includes determining, by the load tracker, whether an idle task is executed in the core, generating, by the load tracker, an event corresponding to a result of the determination, broadcasting, by the load tracker, a generated event to the booster, and setting, by the booster, a QoS minimum value of the core based on the event. The method of operating a CPU may further include registering, by the load tracker, an idle start worker callback and an idle end worker callback in an idle module when the CPU is initialized, and generating, by the load tracker, an idle start worker and an idle end worker when the CPU is initialized.

Method of operating CPU and method of operating system having the CPU

An application processor includes a first core and a second core. The first core is configured to implement a scheduler which monitors a workload of a task of the first core, and the first core is further configured to implement an idle checker which determines whether the second core is idle.
