Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Power consumption is an important parameter to measure chip performance. On different chips that implement the same function, higher power consumption density will cause the temperature of the chip to rise, thereby affecting the reliability of the chip and reducing the service life of the chip. At the same time, high power consumption means more power consumption, therefore, its energy cost is relatively high.

[0027] As mentioned above, the traditional technical solution requires the participation of the CPU when realizing the timing wake-up function, which leads to relatively high power ...

Abstract

The invention relates to the technical field of audio data processing, in particular to an audio playback circuit, an audio player, a chip and electronic equipment, wherein the audio playback circuitcomprises a real-time clock circuit and a digital / analogue converter; the real-time clock circuit is used for transmitting a trigger instruction; the digital / analogue converter is used for obtaining and pushing target audio data according to the trigger instruction. In the pushing process of the target audio data, the participation of a big energy user CPU (Central Processing Unit) is not needed,so that power consumption of the audio playback circuit can be reduced; resources of the CPU can be released, so that the load of the CPU is reduced; in addition, the audio playback circuit do not relay on a DMA mode and can reach higher real-time performance so as to push the target audio data.

Description

technical field [0001] The invention relates to the technical field of audio data processing, in particular to an audio playing circuit, an audio player, a chip and electronic equipment. Background technique [0002] The timer wake-up function is widely used in various technical fields. For example, household appliances, medical instruments, industrial control and other equipment will use the timer wake-up function to more conveniently realize human-computer interaction, thereby providing consumers with more convenient and friendly use. Features. [0003] The technical scheme of traditional technology to realize the timing wake-up function is as follows: when the hardware module in the chip calculates that the current time reaches the user's set time, the hardware module sends a trigger instruction to the central processing unit (CPU, Central Processing Unit), and the CPU responds to the trigger. Instructions execute a series of programs, thereby playing a sound. [0004] ...
