Description

本发明的实施方式
[0041] 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做出创造性劳 动的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。
[0042] 实施例一
[0043] 本实施例提供了一种无线可配置闪存， 参见图 1和 2， 该无线可配置闪存 100用 于实现无线数据存取， 其包括： 用于存储数据的存储模块 11， 用于根据配置参 数解析各种协议的帧的可配置协议模块 12和用于控制无线通信数据的接收、 发 送和无线协议的解析的控制模块 13。
[0044] 在本实施例中， 存储模块 11可包括多个存储位置 （例如存储单元） ， 用于数据 的存取。 可配置协议模块 12包括帧结构描述表 121和帧解析单元 122。 如图 2所示 ， 帧结构描述表 121用于存储第一帧头地址指针 PS1、 第一帧尾地址指针 PE1和通 信协议规定的各字段的值 Al~An， n为当前协议的字段数。 第一帧头地址指针 PS 1和第一帧尾地址指针 PE1指向一个通信协议规定的各字段的值的存储空间。 第 一帧头地址指针 PS1和第一帧尾地址指针 PE1可配置， 因此第一帧头地址指针 PS1 和第一帧尾地址指针 PE1可指向不同的存储空间， 不同的存储空间可用来存储不 同协议所规定的各字段的值。 因此， 可以通过配置第一帧头地址指针 PS1和第一 帧尾地址指针 PE1以改变帧结构描述表 121中所存储的通信协议规定的各字段的 值， 从而可实现将某一特定的通信协议所规定的各字段的值存储在帧结构描述 表 121中。 帧解析单元 132， 用于获取接收的无线通信数据的帧头以获取其使用 的通信协议的各字段的值， 并通过与帧结构描述表 121中的通信协议规定的各字 段的值对比以解析所接收的无线通信数据所使用的协议。
[0045] 在数据通信过程中， 数据包或帧包括三部分： 帧头、 帧数据和校验数据。 对于 不同的通信协议， 数据包或帧中的帧头互不相同。 在本实施例中， 将各种不同 协议的帧的帧头抽象化， 抽象成各字段的值， 而并不关心每个协议的帧的具体 格式。 这样， 就可以用一个简单通用的帧结构描述表来描述各种不同的协议的 帧结构。 而且， 对具体协议的识别就可简化为对协议所规定的各字段的值的比 较。 当有新的无线通信协议出现吋， 只需要将该通信协议所规定的各字段的值 进行存储， 然后配置第一帧头地址指针和第一帧尾地址指针， 使其指向新的通 信协议所规定的各字段的值的存储空间即可。
[0046] 应理解， 在本申请中， "第一"、 "第二"、 "第三 "和"第四"等词语并不是用来限 定先后顺序， 只是为了区分部件的名称。
[0047] 本发明通过可配置协议模块， 使协议规定的各字段的值可重构， 从而使无线可 配置闪存能自适应协议的变化， 而且将协议的识别变成简单的对协议各字段的 值的比对， 从而用一个简单的可配置协议模块就能实现收发多种协议的数据。 因此具有协议自适应性高、 面积小和功耗低的特点。
[0048] 进一步地， 如图 3-6所示， 控制模块 13可包括协议状态描述表 131和状态转移判 决单元 132。 如图 4所示， 协议状态描述表 131用于存储第二帧头地址 PS2、 第二 帧尾地址指针 PE2和状态转移值 VS (1) ~VS (M) 。 其中 M为当前协议的状态 数。 第二帧头地址指针 PS2和第二帧尾地址指针 PE2指向一个通信协议所包含的 状态转移值的存储空间， 控制模块 13根据状态转移值 VS (1) ~VS (M) 控制无 线通信数据的接收、 发送和无线协议的解析。 第二帧头地址指针 PS2和所述第二 帧尾地址指针 PE2可配置从而改变协议状态描述表 131中所存储的状态转移值 VS (1) ~VS (M) 。 具体地， 第二帧头地址指针 PS2和第二帧尾地址指针 PE2可配 置， 因此第二帧头地址指针 PS2和第二帧尾地址指针 PE2可指向不同的存储空间 ， 不同的存储空间可用来存储不同协议的状态转移值。
[0049] 在本实施例中， 将各种不同协议下的操作 （例如发送指令、 响应、 信号的输出 、 数据的采集等） 抽象成协议状态， 针对每个协议定义各自的协议状态以及每 个状态下的具体操作。 这样， 就可以用一个简单通用的协议状态描述表来表示 各种不同的协议所下的操作。 因此， 通过协议状态描述表 131可实现对具体协议 的状态转移值的重构。
[0050] 进一步地， 图 5示出了状态转移判决单元 132的结构示意图。 如图 5所示， 状态 转移判决单元 132包括： 编码值输入电路 1321和逻辑运算电路 1322。 编码值输入 电路 1321用于提供可重构的编码值， 该编码值包括运算编码值 OPC、 当前触发事 件源编码值 Cs和目标事件源编码值 Cd。 通过运算编码值 OPC， 可以确定逻辑运 算电路 1322的运算类型。 例如， 运算编码值 OPC为 2bit， 那么可以定义 4种类型 的逻辑运算， OPC为 3bit， 则可以定义 8种类型的逻辑运算。 OPC的值可接受用户 的配置， 从而适用于不同的协议。 Cs可用于表征当前事件源， 其值也可以进行 配置， 以适用于不同的协议。 Cd用于表征目标事件源， 与当前事件源进行逻辑 运算以确定在当前事件源下是否进行状态转移。
[0051] 具体地， 如图 6所示， 逻辑运算电路 1322可包括逻辑运算器 1322a和选择器 1322 b。 SO表示保持当前状态， S1表示转移到下一个状态。 在一个具体实施例中， OP C为 2bit， 那么 OPC可以有四个取值 00、 01、 10和 11。 逻辑运算器就可以定义四 种运算方式， 例如与、 或、 异或和同或。 当然， 也可以根据实际需要定义更加 复杂的运算方式。 而选择器 1322b的逻辑则可为：

滅 s«t ί: 轉藝:
[0053] 应理解， 逻辑运算电路 1322的具体实现方式有很多种， 本实施例只是列举了其 中一种可能方案。 本领域技术人员在本实施例的教导下， 可以根据实际需要， 设计出各种合适的实现方式。 这也正是本申请的状态机可重构的根本体现。
[0054] 因此， 本申请的状态机的状态转移判决电路也是可重构的， 通过输入不同的编 码值， 就可以重构出不同的状态转移模型以适用于不同的协议。
[0055] 实施例二
[0056] 本实施例提供了另一种结构的无线可配置闪存， 可用于通过多种无线通信介质 进行数据的存取。 如图 7-8所示， 该无线可配置闪存 200可包括： 用于存储数据的 存储模块 11， 用于根据配置参数解析各种协议的帧的可配置协议模块 12， 用于 控制无线通信数据的接收、 发送和无线协议的解析的控制模块 13， 以及用于无 线数据收发的无线收发模块 14。
[0057] 应理解， 本实施例中的存储模块 11、 可配置协议模块 12和控制模块 13的功能和 结构在实施例一中已经进行了详细的描述， 在此不再累述。
[0058] 具体地， 如图 8所示， 无线收发模块 14可包括用于接收和发送声波的声音收发 单元 141， 用于接收和发送电磁波的天线单元 142， 用于接收和发送光波的光收 发单元 143以及用于接收和发送磁信号的磁信号收发单元 144。 声音收发单元 141 可为任何将声音信号转换与电信号相互转换的元器件， 例如麦克风与扬声器。 使用声波进行无线数据通信的传输距离比较近， 但是具有声音收发单元 141的无 线可配置闪存不但可以接收主机发送的无线声波， 还可以接收人发出的声波。 例如， 当将该无线可配置闪存 200应用于手机、 电视等有显示屏幕的电子设备上 吋， 就可以通过人的语音控制无线可配置闪存里面的数据的读取与显示。 天线 单元 142可用于收发多种无线通信协议的数据， 例如蓝牙通信协议、 WIFI通信协 议 ZIGBEE通信协议等。 当然， 天线单元 142可包括一个或多个天线， 而且天线 可以是外置或内置于无线可配置闪存 200中的。 光收发单元 143可为任何将光信 号于电信号相互转换的元器件， 例如光敏传感器和激光器等。 光敏传感器的数 量可为一个或多个， 用于识别不同频率的光线。 磁信号收发单元 144可为任何将 磁场信号与电信号相互转换的元器件， 例如磁性传感器等。 无线收发模块 14中 的一个或多个单元可以外置或内置于无线可配置闪存 200中。
[0059] 应理解， 正是因为本申请中的可配置协议模块 12可自适应于任何无线通信协议 ， 才使得本申请的无线收发模块 14可采用任何无线传输介质 （例如声波、 无线 电波、 光波和磁场等） 的收发元器件， 而不至于显著增加无线可配置闪存的面 积和功耗。
[0060] 实施例三
[0061] 本实施例提供了一种无线通信***， 用于无线存取存储器中的数据。 如图 9所 示， 该***包括： 上述实施例描述的一个或多个无线可配置闪存 200 (以下简称 无线闪存 200) 、 一个或多个直接与无线闪存 200进行数据通信的主设备 21 (例 如笔记本电脑） 以及通过一个或多个接入点 （AP) 22与无线闪存 200进行数据通 信的多个主设备 （例如个人电脑、 服务器、 手机、 电视机等） 。 这些多个主设 备通过局域网或无线局域网连接。 应理解， 直接与无线闪存连接的主设备 （例 如移动电脑 21、 另一个无线闪存 200) 和接入点 22可同吋或基本上同吋连接至无 线闪存 200。 例如， 无线闪存 200可以对等 （pear to pear) 模式或点对点 （ad hoc ) 模式进行无线数据通信。
[0062] 在本实施例中， 两个无线闪存 200之间可相互实现无线数据通信。 结合图 7所示 ， 无线闪存 200包括控制模块 13， 用于控制无线数据的接收、 发送和无线协议的 解析。 因此， 可在无线闪存 200可构造成可接收外部触发信号结构， 从而通过控 制模块 13控制无线数据的接收和发送。 例如， 无线闪存 200在收到外部读触发信 号吋， 可发送无线读指令至另一无线闪存 200。 而接收到读指令的无线闪存 200 则将其所存储的数据无线发送出去。 当相互通信的两个无线闪存 200都是本申请 所公幵的无线可配置闪存吋， 它们可以选择默认的无线通信协议进行通信， 也 可以根据预定的通信策略选择合适的通信协议进行通信， 该通信策略包括但不 限于能量最优、 速率最优或距离最优等。 当相互通信的两个无线闪存只有其中 一个是本申请所公幵的无线可配置闪存、 另一个是普通无线闪存吋， 本申请所 公幵的无线可配置闪存则充当主设备， 以普通无线闪存可识别的通信协议进行 无线数据通信。 因此， 本申请的无线可配置闪存不但可以实现相互无线数据通 信， 还能够实现与现有的普通无线闪存通信， 对普通无线闪存实现读写操作。
[0063] 实施例四
[0064] 本实施例提供了另一结构的无线可配置闪存的结构， 用于无线存取存储器中的 数据。 如图 10所示， 该无线可配置闪存 300可包括： 用于存储数据的存储模块 11 ， 用于根据配置参数解析各种协议的帧的可配置协议模块 12， 用于控制无线通 信数据的接收、 发送和无线协议的解析的控制模块 13， 用于无线数据收发的无 线收发模块 14， 用于为无线可配置闪存 300内的各个模块提供电源的电源模块 15 ， 以及用于对提供给无线可配置闪存 300内的一个或多个模块的一个或多个电压 或电流进行调制的电源调制模块 16。
[0065] 应理解， 本实施例中的存储模块 11、 可配置协议模块 12、 控制模块 13和无线收 发模块 14的功能和结构在实施例一和实施例二中已经进行了详细的描述， 在此 不再累述。
[0066] 电源模块 15可为电池， 例如锂电池， 从而使无线可配置闪存 300可成为一个可 运行的独立设备。 电源模块 15可以是可充电的， 并可通过外部进行充电。 当然 ， 电源模块 15也可直接从外部获得电能。
[0067] 电源调制模块 16用于为无线可配置闪存 300内的各个模块提供经调制的稳定输 出电压。 一方面， 电源调制模块 16可升高或降低电源模块 15提供的电压从而为 无线可配置闪存 300内的各个模块供电。 例如， 电源调制模块 16可为无线可配置 闪存 300的各个模块提供不同的电压。
[0068] 实施例五
[0069] 本实施例提供了另一结构的无线可配置闪存的结构， 用于无线存取存储器中的 数据。 如图 11所示， 该无线可配置闪存 400可包括： 用于存储数据的存储模块 11 ， 用于根据配置参数解析各种协议的帧的可配置协议模块 12， 用于控制无线通 信数据的接收、 发送和无线协议的解析的控制模块 13， 用于无线数据收发的无 线收发模块 14， 以及用于对无线通信数据进行加密或者解密的密码模块 17。
[0070] 应理解， 本实施例中的存储模块 11、 可配置协议模块 12、 控制模块 13和无线收 发模块 14的功能和结构在实施例一和实施例二中已经进行了详细的描述， 在此 不再累述。
[0071] 如图 11所示， 密码模块 17包括加密模块 171和解密模块 172。 密码模块 17可对存 储在无线可配置闪存 400中的数据或者是传输至另一个设备的数据进行加密或解 密以确保数据安全。 密码模块 17可采用的各种加密技术， 例如有线等效加密技 术 （WEP) 、 Wifi网络完全存取 （WPS) 、 数据解密标准 （DES) 、 高级加密标 准 (AES) 等等。
[0072] 实施例六
[0073] 本实施例提供了一种电子设备， 该设备包含上述实施例中所描述的任意一种无 线可配置闪存。 例如， 该电子设备可为计算机、 手机、 数字电话、 视频设备、 智能卡、 个人数字助理 （PDA) 、 电视机、 电子游戏机、 数字照相机、 电子记 事本、 音频播放器、 录音器、 与数字版权管理有关的电子设备、 网卡、 GPS设备 等。
[0074] 以上所揭露的仅为本发明一种较佳实施例而已， 当然不能以此来限定本发明之 权利范围， 本领域普通技术人员可以理解实现上述实施例的全部或部分流程， 并依本发明权利要求所作的等同变化， 仍属于发明所涵盖的范围。
