Description

一种存储卡的数据处理方法及装置 技术领域
本发明涉及电子设备应用领域，尤其涉及一种存储卡的数据处理方法及装置。
背景技术
随着电子设备应用的不断发展，数码相机、多媒体播放器等便携式装置的用户日益增多，用户对便携式装置，如智能终端，存储卡的数据处理要求也越来越高。现有技术提供了一种安全数码卡数据的处理技术，其方法如下：

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种存储卡的数据处理的方法，如图1所示，所述方法包括：
步骤101、确定终端使用的系统个数和各系统所需存储空间的容量。
所述各系统所需存储空间的容量总和不超过存储卡本身空间的容量大小。
步骤102、根据所述系统个数和所述容量对存储卡的存储空间进行区域划分。
所述存储卡可以包括SD(Secure Digital，安全数码)卡、MMC(Multimedia Card，)多媒体卡和TF(Trans Flash，内存)卡等。
所述区域划分可以通过以下两种方式来实现：
根据系统个数将存储卡的存储空间平均分配，分配后的各区域大小相同，将各系统所需的存储空间的容量一一对应的分配到各区域。当系统所需的存储空间大于对应的区域时，将未分配到各系统的存储空间划分到该区域或将不常用系统的存储空间划分到该区域，直到该区域不小于其对应的系统所需的存储空间为止。
或，根据各系统所需存储空间的容量，对存储卡的存储空间进行区域划分。划分后的各区域与各系统所需的存储空间容量一一对应，且每一个区域均不小于其对应的系统所需的存储空间的容量。
步骤103、建立划分的区域与所述系统之间的映射关系，以便于各系统从对应的存储卡区域中存储或读取数据。
所述映射关系是指划分的存储卡区域与所述系统一一对应，各系统只从其对应的存储卡区域中存储或读取数据，不会访问到其它系统对应的区域。
本发明实施例提供的一种存储卡的数据处理的方法，能够确定终端使用的系统个数和各系统所需存储空间的容量，根据系统个数和容量对存储卡的存储空间进行区域划分，建立划分的区域与系统之间的映射关系，以便于各系统从 对应的存储卡区域中存储或读取数据。现有技术中，当智能终端有多个系统运行时，智能终端对安全数码卡数据处理的速率和正确率降低。与现有技术相比，本发明中，各系统能够从对应的存储卡区域中存储或读取数据，未映射到系统的区域或者与系统不对应的区域不能被存储或读取，避免了访问到其它系统数据的交叉现象，提高了智能终端对安全数码卡数据处理的速率和正确率。
本发明实施例还提供了一种存储卡的数据处理的方法，作为对图1所示方法的具体说明，步骤103、建立划分的区域与所述系统之间的映射关系，以便于各系统从对应的存储卡区域中存储或读取数据，包括：
建立所述划分的区域的物理地址与对应系统的映射关系。
下面通过一个使用场景来说明该映射关系：
在一个智能终端中，如手机，开机启动过程中，检测到有存储卡，判断存储卡是否已经完成了区域的分配。如果完成了区域的分配，则将各区域的物理地址范围映射到相应的系统，各系统根据物理地址范围进行逻辑映射，并在对应的区域存储或读取数据。未映射到系统的部分，包括未映射到所有系统的部分和映射到该系统以外的系统的部分，该系统均没有访问权限，无法存储或读取数据。若存储卡未完成区域的分配，则执行存储卡的区域分配命令，区域分配完成后，参照上述步骤执行映射关系的建立。
或者在使用过程中，热插拔检测到有存储卡，提示用户没有按照系统进行区域的分配，需要重启手机执行区域的分配，则重新开机，接下来按照上述开机启动步骤执行映射关系的建立。
本发明实施例提供的一种存储卡的数据处理的方法，通过建立划分的区域的物理地址与对应系统的映射关系，各系统只能从对应的区域中存储或读取数据，对该系统以外的系统所对应的区域和所有系统对应区域以外的区域没有访问权限。避免了访问到其它系统数据的交叉现象，降低了存储或读取数据的复杂度，提高了智能终端对安全数码卡数据处理的速率和正确率。

步骤202、当所述系统所需存储空间的容量之和大于所述存储卡的存储空间的总容量时，减少所述各系统所需存储空间的容量之和，直到所述系统所需存储空间的容量之和不大于所述存储卡的存储空间的总容量。
可选的，所述区域划分是指，按照所述系统个数和每个系统对应的容量对存储卡的存储空间进行划分。所述系统个数不超过划分后的区域个数。所述系统只与所述区域中的一个对应。所述系统对应区域的存储空间的容量不小于所述系统所需的存储空间的容量。
