以下结合附图对本发明的具体实施方式进行详细的说明。 首先,对以下各 实施例中的用词和术语进行解释: 所谓主机(host device ),是指安全数码接口主设备,可以是各种电子设备, 包括但不限于: 笔记本电脑 (Notebook Computer ) , 手机、 个人数字助理 (Personal Digital Assistant, PDA ), 平板电脑(Tablet PC )、 数码相机、 数码 摄像机、 MP3/MP4播放器。 当以下各实施例提到曱与乙相 "耦合" 时, 是指通过曱的电信号与通过乙 的电信号发生物理上的确定关联, 这包括曱与乙通过导线等直接连接, 或者通 过另一个部件丙间接相连,也包括曱与乙之间如变压器那样通过电磁感应使经 过各自的电信号发生关联。 当本发明提及 "第一"、 "第二"等序数词时, 除非根据上下文其确实表达 顺序之意, 应当理解为仅仅是起区分之用。 如图 1所示, 在本发明的一个实施例中, 一种安全数码(Secure Digital,
SD )卡 100包括: 安全数码输入输出 ( Secure Digital Input and Output, SDIO ) 接口 101、 选择开关 102、 存储单元 103、 基带处理单元 104、 射频电路 105 和天线 106。 其中所述 SDIO接口 101用于提供主机 200和所述存储单元 103 之间的数据和控制接口; 存储单元 103 , 用于存储数据; 所述选择开关包括第 一支路和第二支路, 当所述选择开关连通所述第一支路时, 所述存储单元 103 的读写接口与所述 SDIO接口 101相耦合, 当所述选择开关连通所述第二支路 时, 所述存储单元 103的读写接口与所述基带处理器 104相耦合; 所述基带处 理器 104 , 与所述射频电路 105相耦合, 用于处理基带数据; 射频电路 105 , 与所述基带处理器 104相耦合,用于将所述基带处理器 104输出的数据转换为 射频信号发往天线 106, 以及, 将来自天线 106的射频信号转换为数字信号发 往所述基带处理器 104; 天线 106 , 用于发送所述射频电路输出的射频信号, 以及接收来自网络的射频信号。 该实施例提供的 SD卡, 能够在 SD卡上实现上网的功能, 无须对主机本 身进行改造, 节约了用户的成本, 提高了通用性。 基带处理器 104 可以为蜂窝网络的基带处理器, 例如全球移动系统 ( GSM )、 码分多址( CDMA ), 宽带码分多址( WCDMA ), LTE等蜂窝网络 制式, 本发明对此不作限制。
如图 2所示, 射频电路 105通常包括一个射频收发器(Radio Frequency Transceiver ) 1051 , 该器件的作用是将数字信号调制成射频信号, 以及将接收 到的射频信号解调成数字信号。 射频电路 105 通常还可包括一个功率放大器 1052,用于将射频收发器 1051输出的射频信号放大,其输出端耦合到天线 106。
为了适应 SD卡的尺寸, 天线 106具体可以为印制天线, 但是本发明的实 施例不局限于此, 也可以其他任何本领域技术人员所习知的天线。
选择开关 102可以是电子开关, 该类器件在现有技术中有成熟的产品, 本 发明实施例对此不作限定。
如图 3A和图 3B所示, 在本发明的一个实施例中, 选择开关 102有一个 控制输入端 1021 , 该控制输入端 1021用于接收切换控制信号, 所述切换控制 信号用于控制选择开关 102在所述第一支路和所述第二支路之间的切换。
所述切换控制信号可以由主机 200产生,例如主机 200接收用户的一个指 令, 通过 SDIO接口 101输出所述切换控制信号到选择开关的控制输入端, 也 就是说, 在这种情况下 (如图 3A所示), 所述控制输入端 1021与 SDIO接口 101相耦合。 当然, 主机 200也可以通过程序自动产生所述切换控制信号。
所述切换控制信号也可由基带处理器 104产生。例如基带处理器 104通过 其通用输入输出( General Purpose Input and Output , GPIO )接口向控制输入端 1021输出所述切换控制信号, 也就是说, 在这种情况下 (如图 3B所示), 基 带处理器 104与输入控制端 1021相耦合。 基带处理器 104可以通过程序产生 所述切换控制信号。
如图 4 所示, 在本发明的一个实施例中, 可以通过一个切换控制器 107 来控制选择开关 102在所述第一支路和所述第二支路之间进行切换。切换控制 器分别与 SDIO接口 101和控制输入端 1021相耦合, 用于当 SDIO接口 101 上有信号传输时控制选择开关 102连通所述第一支路。 通常来说, SDIO接口 101上有信号传输表明当前主机 200正尝试读写存储单元 103 , 此时需要使选 择开关连通所述第一支路。 可选的, 切换控制器 107还用于当 SDIO接口处于 空闲状态时控制选择开关 102连通所述第二支路。 当 SDIO接口空闲时, 主机 200没有读写存储单元 103 , 此时基带处理器 104可以从存储单元 103读取数 据并通过无线网络发送。 当然, 当 SDIO接口空闲的时候, 选择开关 102并不 一定要连通所述第二支路,可以通过来自主机 200或者基带处理器 104的控制 信号来进一步的控制切换控制器 107输出所述切换控制信号, 例如, 当 SDIO 接口 101空闲时,只有在接受到来自主机 200或者基带处理器 104的切换指令 时, 切换控制器 107才控制选择开关 102连通所述第二支路。
切换控制器 107可以有多种实现方式。 例如,切换控制器 107可以是一个 比较器, 如图 5所示, 比较器 1070的输入端与 SDIO接口 101相耦合, 输出 端与控制输入端 1021相耦合。 比较器 1070 比较其输入端的电平和参考电平 VCC, 根据比较的结果输出所述切换控制信号。 当 SDIO接口 101上有信号传 输时, SDIO接口 101上的电平会发生变化,可以将参考电平 VCC设置为 SDIO 接口 101空闲时的电平,或者设置为 SDIO接口 101空闲时的电平和传输信号 时的电平之间的某个电平, 这样当 SDIO接口 101上的电平会发生变化时, 比 较器 1070即根据比较结果输出所述切换控制信号。 例如, 所述参考电平 VCC 设置为 SDIO接口 101空闲时的电平, 当比较器 1070检测到 SDIO接口 101 上的电平高于所述参考电平 VCC时, 控制选择开关 102连通所述第一支路, 当比较器 1070检测到 SDIO接口 101上的电平低于于所述参考电平 VCC时, 控制选择开关 102连通所述第二支路。 当然, 本领域技术人员知道, 也可以把 比较器 1070设计成当 SDIO接口 101上的电平低于所述参考电平 VCC时,控 制选择开关 102连通所述第一支路, 当 SDIO接口 101上的电平高于于所述参 考电平 VCC时, 控制选择开关 102连通所述第二支路。
另一种实现方式是通过一个数字信号处理器 (Digital Signal Processor, DSP )来实现所述切换控制信号的输出。 如图 6所示, 在一个实施例中, 切换 控制器 107包括计数器 1071和数字信号处理器 1072。 计数器 1071的输入端 与 SDIO接口 101相耦合,计数器 1071的输出端与数字信号处理器 1072相耦 合。 计数器 1071用于对 SDIO接口 101上传输的信号进行计数。 数字信号处 理器 1072与控制输入端 1021相耦合, 用于读取计数器 1071输出的计数值, 并根据所述计数值输出所述切换控制信号。 具体来说, 数字信号处理器 1072 可以周期性的读取所述计数值, 判断所述计数值是否在增大, 如果增大, 说明 SDIO上有信号传输,此时数字信号处理器 1072输出切换控制信号控制选择开 关 102连通所述第一支路, 如果所述计数值没有增大, 则说明 SDIO接口上没 有信号传输, 此时数字信号处理器可以输出切换控制信号控制选择开关 102 连通所述第二支路。
所述切换控制信号可以有多种形式。在一些实施例中, 所述切换控制信号 包括第一支路连通信号和第二支路连通信号,其中所述第一支路连通信号控制 选择开关 102连通所述第一支路,而第二支路连通信号控制选择开关 102连通 所述第二支路。在这些实施例中, 负责输出所述切换控制信号的器件在控制选 择开关 102连通所述第一支路时,输出所述第一支路连通信号; 当该器件控制 选择开关 102连通所述第二支路时,输出所述第二支路连通信号。 负责输出所 述切换控制信号的器件在何时控制选择开关 102连通所述第一支路,在何时控 制选择开关 102连通所述第二支路,在前述的各个实施例中已有描述, 此处不 再赘述。
在另一些实施例中, 所述切换控制信号具体为状态切换信号, 所述状态切 换信号用于控制选择开关 102从当前连通的支路切换到另一支路。例如选择开 关 102当前连通所述第一支路, 当选择开关 102接收到所述状态切换信号时, 选择开关 102 从连通所述第一支路切换到连通所述第二支路; 而若选择开关 102当前连通所述第二支路, 当选择开关 102接收到所述状态切换信号时, 选 择开关 102从连通所述第二支路切换到连通所述第一支路。 在这些实施例中, 负责输出所述切换控制信号的器件在输出所述状态切换信号时需要知道当前 选择开关 102连通哪一支路。如图所示, 这可以通过在选择开关 102上增加一 个状态输出端 1022来实现。 负责输出所述切换控制信号的器件通过状态输出 端 1022读取选择开关 102当前连接哪一支路的状态, 以决定输出所述状态切 换信号。
选择开关 102、 切换控制器 107可以为分立的器件, 也可以集成在一块芯 片中,具体可以集成在一个现场可编程门阵列( Field Programmable Gate Array, FPGA ) 中。
另外, 以上实施例中分别说明的各技术、 系统、 装置、 方法以及各实施例 中分别说明的技术特征可以进行组合,从而形成不脱离本发明的精神和原则之 内的其他的模块, 方法, 装置, 系统及技术, 这些根据本发明实施例的记载组 合而成的模块, 方法, 装置, 系统及技术均在本发明的保护范围之内。 显然, 本领域的技术人员应该明白, 上述的本发明的各单元或各步骤可以 用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多 个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码 来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行。 或者将它们 分别制作成各个电路模块,或者将它们中的多个单元或步骤制作成单个电路模 块来实现。 这样, 本发明不限制于任何特定的硬件和软件结合。
以上只是本发明的较佳实施例, 并非用于限定本发明的保护范围。 凡在本 发明的精神和原则之内所作的任何修改、 等同替换、 改进等, 均包含在本发明 的保护范围内。
