Description

Clock control method and electronic device therefor

Various embodiments disclosed in this document relate to a method for controlling a clock and an electronic device therefor.

The processor included in the electronic device may generate a clock by using a clock generator, and may perform a plurality of functions based thereon. The processor may include at least one core. The core may be understood as a component that performs operations such as operation and/or function operation of an electronic device based on a generated clock value. Here, the clock may be referred to as a unit indicating the operation clock and/or speed of the information processing apparatus, and as the clock increases, the operation speed of the information processing apparatus may increase.

The electronic device may include at least one processor. The at least one processor may be divided into a main processor and/or an auxiliary processor. For example, the main processor may be configured to control functions performed in the electronic device in general, while the auxiliary processor may be set to specifically operate some of the functions. Each processor may send and receive signals physically and/or electrically. The signal may include a control signal of a clock value required to perform a plurality of functions.

For example, the coprocessor may support an adaptive change of the operating clock. For example, the coprocessor may change its operating clock to handle functions required by the main processor. By increasing the operating clock, the processing speed and data throughput of the coprocessor can be increased. However, an increase in the operating clock may result in an increase in power consumption and heat generation by the coprocessor.

For a function that the user does not want to be provided, the electronic device may not normally stop the corresponding function. For example, the main processor may cause the auxiliary processor to perform a first function. In order to perform the first function, an operation clock of the coprocessor may be controlled. In the main processor, the operation related to the first function is terminated, but in the auxiliary processor, the termination of the first function may not be processed. For example, the main processor may provide a signal (eg, an interrupt) instructing the auxiliary processor to terminate the first function. A coprocessor may, for example, experience an interrupt storm in which it receives many signals in a short amount of time. In this case, the auxiliary processor may omit the release of the clock for performing the first function. In this case, a problem of wasting power consumption may occur because the clock value to be released is continuously maintained.

An electronic device according to an embodiment disclosed herein includes a main processor, an auxiliary processor configured to perform a plurality of audio data processing functions, and a clock control module operatively connected to the main processor and the auxiliary processor wherein the main processor transmits information about first functions related to the operation of the main processor among the plurality of audio data processing functions to the clock control module, and the auxiliary processor is configured to process the plurality of audio data transmits information on second functions executed by the auxiliary processor among functions to the clock control module, wherein the clock control module receives the first functions and the second functions from the main processor and the auxiliary processor It may be determined to terminate the execution of at least one of the second functions based on the information about the second functions.

A method for providing a clock control function according to an embodiment disclosed in this document includes a first method associated with an operation of a main processor among a plurality of audio data processing functions performed by a main processor in an auxiliary processor included in the electronic device. transmitting information about functions to a clock control module, the coprocessor transmitting information about second functions executed in the coprocessor among the plurality of audio data processing functions to the clock control module; and determining, by the clock control module, to end execution of at least one of the second functions based on the information about the first functions and the second functions received from the main processor and the auxiliary processor. may include

The coprocessor may store the above operation information in a memory (eg, the memory 270 of FIG. 2 ).

Also, the main processor (eg, the main processor 210 of FIG. 2 ) may transmit operation information for each function to the clock control module.

The operation of controlling the execution of the specified functions may include an operation of applying a clock setting value corresponding to the specified functions to perform the specified functions (eg, outputting an image and/or outputting a plurality of sound effects).
