Problems solved by technology

However, in this sleep scheme, the waiting time is not easy to define, and after the waiting time is determined, it must wait every time, which also affects the response speed of the chip.

Embodiment Construction

[0056] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0057] see figure 1 , is a schematic diagram of the connection between the chip and the processor according to the embodiment of the present disclosure. The chip 100 is connected to the processor 200 or a host (host) through a data transmission interface 101 (for example, a high-speed data interface) for data transmission. In one embodiment, the chip 100 may be a storage device, such as a solid state disk.

[0058] In the embodiment of the present disclosure, by detecting and recording the data transmission status of the data transmission interface 101, the dormancy of the chip is dynamically adjusted, and the response speed of the chip is improved.

Abstract

The invention relates to a method and device for controlling dormancy of a chip. The method comprises the steps of obtaining duration that a data transmission interface of the chip stops data transmission; judging whether the duration meets preset conditions or not; when the duration meets the preset conditions, obtaining the data transmission condition between the moment that the data transmission port stops data transmission and the moment of ending previous real dormancy of the chip, wherein the real dormancy is the dormancy of which the dormancy duration exceeds a preset threshold; and determining whether the chip is controlled to enter the dormancy or not according to the data transmission condition and preset historical dormancy data. According to the method and the device, the dormancy of the chip is determined according to the historical dormancy condition, the data transmission quantity, the data transmission times and the data transmission time, and the effective dormancy rate of the chip is improved.

Description

technical field [0001] The present disclosure relates to the technical field of chip control, and in particular, to a chip sleep control method and device. Background technique [0002] In an electronic device, each chip is connected to a processor through a data transmission interface to read and write data. In order to reduce power consumption, the chip will enter sleep mode and power off some modules when the data transmission interface is idle and there is no data transmission. However, when the chip enters the sleep mode, new data may be read and written immediately, and at this time, the chip needs to power on the modules that have been powered off again. In this case, not only the response speed of the chip is affected, but also the power consumption loss due to repeated power-on is greater. [0003] In related technologies, in addition to the above-mentioned unconditional sleep, there is also a sleep scheme, that is, when the data transmission interface enters the ...
