Embodiment 1
[0025] refer to figure 1 , shows a flowchart of steps of a power consumption control method in an embodiment of the present invention. The method is applied to a mobile terminal, and the mobile terminal includes a memory and a CPU, and the specific steps include:
[0026] Step 101: Obtain a first power consumption parameter of the memory.
[0027] In the embodiment of the present invention, the mobile terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a vehicle-mounted terminal, a wearable device, and a pedometer.
[0028] In a specific application, the memory may be DRAM (Dynamic Random Access Memory, dynamic random access memory), the temperature of the MOS transistor (metal oxide semiconductor, field effect transistor) on the DRAM will gradually rise during operation, and after the temperature of the MOS transistor rises, The power consumption will be increased. Therefore, the first power consumption param...
Embodiment 2
[0034] refer to figure 2 , shows a flow chart of specific steps of a power consumption control method in an embodiment of the present invention. Applied to a mobile terminal, the mobile terminal includes a memory and a CPU, and the specific steps include:
[0035] Step 201: Obtain the self-refresh frequency of the memory.
[0036] In the embodiment of the present invention, the first power consumption parameter is a self-refresh frequency. The reason why the self-refresh frequency is used as the first power consumption parameter of the memory is that the applicant has found through a lot of research and experiments that as a data storage component, DRAM has data volatility, so it needs to perform self-refresh at a certain frequency to maintain data integrity , its self-refresh frequency depends on the temperature. When the temperature is higher, the DRAM self-refresh frequency and DRAM leakage current will increase significantly, and the power consumption will also increase...
Embodiment 3
[0058] refer to Figure 5 , shows a structural block diagram of a power consumption control apparatus 300 in an embodiment of the present invention. The device includes a memory, a CPU; the device also includes:
[0059] A first obtaining module 310, configured to obtain a first power consumption parameter of the memory;
[0060] The first execution module 320 is configured to perform power consumption suppression processing on the CPU if the first power consumption parameter satisfies a first preset condition.
[0061] Preferably, refer to Image 6 ,exist Figure 5 On the basis of the above power consumption control means:
[0062] The first power consumption parameter includes: self-refresh frequency;
[0063] The first acquisition module 310 includes:
[0064] The first acquiring submodule 3101 is configured to acquire the self-refresh frequency of the memory;
[0065] The first execution module 320 includes:
[0066] The first execution sub-module 3201 is configure...
