Abstract

The invention provides a terminal hot start method and a terminal hot start apparatus. The method comprises the following steps: firstly a second storage unit stores a hot start code, and a start code storage module stores the start code; then, an execution module receives a first command, executes the start code in the start code storage module, reads the hot start code from the second storage unit, and stores the hot start code in a caching module; and then, the execution module executes the hot start code in the caching module, and makes a first storage unit exit from a self-refresh mode. Since the hot start code is stored in the second storage unit in advance, when a mobile device is in a sleep mode, power supply for the caching module is not needed, power consumption of the mobile device in the sleep mode is reduced greatly, and hardware cost is also reduced.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a terminal hot start method and device. Background technique [0002] The startup of mobile devices is usually divided into cold startup and hot startup. Cold start refers to the startup process after the system is powered on again when the mobile device is completely powered off. Warm start refers to the process of a mobile device recovering from a low power consumption mode (sleep mode) to a normal operation mode. Since the hot start code is stored in SRAM, and SRAM is located in the processor of the mobile device, when the mobile device enters the sleep mode, it needs to continue to supply power to the SRAM to ensure that the mobile device can recover when the mobile device exits the sleep mode To normal operating mode. [0003] In this way, not only will the power consumption of the mobile device in sleep mode increase (the larger the SRAM capacity, the higher the power...
