Embodiment Construction

[0012] The SD driver architecture provided by the Intel CPU 310 / 320 series platform is as follows: figure 1 As shown, it includes SD storage layer, SD bus driver layer, and SD controller layer.

[0013] 1. Treatment before the invention, see figure 1 , figure 2 :

[0014] After the power management module 201 wakes up from sleep, the SD controller layer 104 simulates the SD card pulling operation 202 to notify the SD bus driver layer 103 and the SD storage layer 102 that the SD card has been pulled out from the card slot. Afterwards, the card insertion action 204 is simulated to notify the SD bus driver layer 103 and the SD storage layer 102 that an SD card has been inserted into the card slot. The card removal operation of the SD bus driver layer 103 takes 5-6 seconds and has a higher priority, and then the card insertion action of the SD bus driver layer 103 takes 1-2 seconds. In this way, after the SD card is inserted and woken up from sleep, it will take 6-8 seconds f...

Abstract

The invention discloses an optimization processing method for a sleep waking SD card (Secure Digital Memory Card) of a smart mobile phone. During waking, the process of removing and inserting a card is no longer simulated, but a command of a reset card is sent out and an SD card storage layer is treated specially to ensure that reading, writing and accessing can be carried out normally in time when the modified SD card is waked up. The optimization processing method for a sleep waking SD card of a smart mobile phone has the advantage that the time consumption of SD drive is greatly reduced during sleep waking, and the sleep waking takes only 1 second so as to ensure that reading, writing and accessing can be carried out rapidly when the modified SD card is waked up; meanwhile, the problems of screen frozen and system halted when inserting the SD card for sleep waking are solved, and the application program in SD beforehand runs fast, so that the user can be given an wake-use real-time experience, that is, immediately accessing the SD and other applications after waking.

Description

technical field [0001] Compatible with smartphones using Intel CPU 310 / 320 series platforms and Intel CPU 270 series platforms Background technique [0002] At present, with the improvement of people's living standards and the needs of communication, smart phones are becoming more and more popular. In order to attract more people's attention, various mobile phone manufacturers increase the selling points of their products. Many functions have been added to the smartphone. For example, it is required to support faster and larger-capacity SD cards, which are a new generation of memory devices based on semiconductor flash memory. SD cards are jointly developed by Panasonic, SanDisk and Toshiba on the basis of MMC cards (MultiMedia Cards). . It is about the size of a postage stamp and weighs about two grams. Memory cards compatible with SD cards also include MiniSD cards (Mini Secure Digital Memory Card) and MicroSD cards (Micro Secure Digital Memory Card). The latter two ar...
