现有的各种操作系统多具有文件的自动执行机制,但是它们仅仅支持光 盘以及本地磁盘上指定文件的自动执行功能。 以 t软公司的 WINDOWS 98 操作系统为例,在光盘插入电脑主机的光盘驱动器后,操作系统会根据有关 协议(例如 MMC 3、 SCSI等)向所连接的设备发出问询命令以获得该设备 的设备状态, 并且根据设备报告的设备状态(光盘驱动器)来识别和配置该 设备。 设备识别配置完毕后, 操作系统会询问设备是否有光盘插入, 如果应 答为有光盘插入, 则读取光盘中的文件。 如果该光盘的根目录下有自动执行 配置文件,操作系统将会首先对该自动执行配置文件进行处理, 即根据该自 动执行配置文件所遵循的相关协议找出指定文件,执行该指定文件。在该指 定文件运行过程中, 操作系统还可对光盘进行数据读取操作。

图 5示出了本发明的第四个实施例,是将第三个实施例改进为通过计时 来控制半导体存储装置复位的时机。 具体实施方式
现有的各种操作系统中,按照其自动执行机制所支持的设备类型的不同 可分为两类: 第一类操作系统只支持光盘中指定文件的自动执行, 包括 WINDOWS 9X、 WINDOWS XP等。 第二类操作系统除支持光盘外, 还可支 持本地磁盘内指定文件自动执行, 包括 WINDOWS 2000、 WINDOWS ME 等。 ·
根据本发明,当一种半导体存储装置连接到主机上以第一类操作系统为 平台进行操作时,可将该半导体存储装置模拟为插入光盘的光盘驱动器,从 而激活操作系统的自动执行机制。对于第二类操作系统而言, 既可以将半导 体存储装置模拟为插入光盘的光盘驱动器,按照与第一类操作系统相同的方 法去激活自动执行机制;也可以将半导体存储装置模拟为本地磁盘来激活自 动执行机制,在自动执行机制运行过后,会自动转入读取半导体存储装置内 的文件系统, 准备开始对本地磁盘进行读、 写等数据操作, 即进入本地磁盘 的常规存储功能。
半导体存储装置模拟各种现有存储装置例如光盘,软盘,夺地磁盘等等 的方法已由本申请人在先的中国专利申请"一种多功能半导体存储装置" (申 请号 01114883.7 )揭示和公开, 该申请的全部内容在此引用。
以下将结合图 1 对本发明的第一个实施例进行详细说明。 在该实施例 中, 所述半导体存储装置连接的主机的操作系统是第二类操作系统, 即所述 操作系统除支持光盘外,还可支持本地磁盘内文件自动执行,这类操作系统 包括 WINDOWS 2000、 WINDOWS ME等。
针对主机的操作系统, 实施例 1中将半导体存储装置模拟为本地磁盘, 实现指定文件的自动播放。 图 1示出了本实施例的流程。
参见图 1 , 当半导体存储装置连接到主机后, 首先进行初始化过程(步 骤 1 )。 半导体存储装置的初始化属现有技术, 在此不作赘述。 初始化完成 之后, 操作系统对该新连接设备发出问询命令, 以获取连接的设备类型; 半 导体存储装置接到该问询命令(步骤 2 )并根据预设的设备类型值进行应答。 本领域普通技术人员可以理解,新连接的设备对于操作系统的问询命令的应 答将决定操作系统对设备的识别、 配置以及随后的不同处理, 包括操作系统 的自动执行机制是否被激活, 自动执行阶段的进程等等。 例如, 如果应答设 备类型为移动磁盘, 操作系统将不启动自动执行。如果应答设备类型为光盘 驱动器或者本地磁盘,操作系统的自动执行机制将可能被激活从而使指定文 件 (如果存在的话)进行自动执行。
本实施例中, 由于所述连接的半导体存储装置预设为模拟本地磁盘, 所 以, 操作系统从连接的设备获得的应答为本地磁盘(步骤 3 )。 根据该应答, 操作系统将把半导体存储装置视为本地磁盘,根据预设的自动执行机制在半 导体存储装置的存储空间中查找符合操作系统要求的自动执行配置文件(步 骤 4 )。 如果找不到自动执行配置文件, 则自动跳出自动执行而开始进入半 导体存储装置的常规存储功能; 如果能找到自动执行配置文件, 则读取该文 件包含的信息 (步驟 5 ), 根据这些信息在指定路径中寻找指定的要执行的 文件 (简称指定文件)。 如果不能找到指定文件, 则跳出自动执行过程, 开 始半导体存储装置的常规存储功能。 如果能找到指定文件 (步驟 6 ), 则打 开执行该指定文件 (步骤 7 ), 同时进入半导体存储装置的常规存储功能, 激活自动执行机制的过程结束。
在图 1中, 步骤 7是由操作系统控制指定文件的运行, 其运行的过程和 处理由操作系统控制,本发明的半导体存储装置在激活上述指定文件的自动 执行后进入到常规的存储功能, 而与指定文件的自动运行过程和结果无关。 例如, 根据指定文件的不同, 执行时间、 执行结果可能不同, 结束执行的方 式也可能不同。 例如指定文件是文本类型, 打开后需要用户操作或干预才能 关闭; 如果指定文件是一个可执行文件, 运行完毕后可能自动关闭。 在指定 文件开始执行后, 激活操作系统的自动执行机制的过程即告结束, 进入半导 体存储装置的常规存储功能。 故此, 步骤 7用虚线框示出。
根据本发明,所述指定文件的存放地点并不局限于在连接的半导体存储 装置上。操作系统允许指向指定文件的路径可以是绝对路径或相对路径, 只 要根据该路径能够找到指定文件即可。指定文件可以存放于主机硬盘、光盘、 其他可连接的移动存储盘上, 甚至可以是存放在与主机建立连接的网络上。 在指定文件执行过程中如果由于存储介质被移动或改变,致使指定文件不可 访问, 执行过程将会中断, 自动进入半导体存储装置的常规存储功能。
对于第一类操作系统, 包括 WINDOWS 9X、 WINDOWS XP等, 其不 支持本地磁盘上的文件自动执行, 当所述半导体存储装置在连接主机时,要 进行设置以使该半导体存储装置模拟成有光盘插入的光盘驱动器来激活这 一类操作系统的自动执行机制。
此外,现有的操作系统对光盘内文件的自动执行机制由于默认光盘是不 可擦写的, 所以自动执行完毕后, 不会转入常规存储功能。 但是, 本发明的 半导体存储装置尽管是模拟光盘驱动器来激活操作系统的自动执行机制,在 完成此项任务以后,半导体存储装置还要能够实现其常规的存储功能,也就 是说,对于利用半导体存储装置执行自动执行的方法来说, 需要实现自动执 行功能到常规存储功能的切换而将文件自动执行功能和半导体存储装置的 常规存储功能结合起来。 附图 2是本发明的第二个实施例, 示出了当一个半 导体存储装置连接到以第一类操作系统运行的主机上时,半导体存储装置模 拟一个光盘驱动器以激活操作系统的自动执行机制,并且在此之后切换到半 导体存储装置常规存储功能的流程。
如图 2所示,在半导体存储装置连接主机后首先进行初始化操作(步骤 1 ), .初始化操作完毕后, 检测设备切换标志 (步骤 2 )。 所述设备切换标志 存储在所述半导体存储装置的存储空间中,用于引导设备类型切换过程。在 本实施例中, 将设备切换标志预设为一个第一预定值, 例如为 "1"。 如果检 测到所述的设备切换标志值为 "1" (步骤 3 ), 则进行步骤 4, 设置当前设备 类型标志设为光盘驱动器。 当前设备类型标志用于标明设备的类型,保存在 所述半导体存储装置中,并且设定以所述的当前设备类型标志作为对操作系 统问询命令的应答,操作系统将根据当前设备类型标志来识别连接主机的设 备并且安装配置设备。 在接到操作系统发出的问询命令(步骤 5 )后, 半导 体存储装置将在步骤 4 中设置好的当前设备类型标志即光盘驱动器应答给 操作系统(步骤 6 )。 操作系统收到应答后, 将半导体存储装置视为未插入 光盘的光盘驱动器。在上述步骤完成后, 已将半导体存储装置模拟为光盘驱 动器,接下来操作系统对模拟的光盘驱动器执行自动执行过程(步骤 7 ), 详 细的自动执行过程将在后文中参照图 3做出说明。
另一方面,所述半导体存储装置内的微处理器将设备切换标志由第一预 定值修改为一个不同于所述第一预定值的笫二预定值,例如为 "0" (步骤 8 ), 然后发出重新启动 (复位)半导体存储装置的命令(步骤 9 )。 复位相当于 将半导体存储装置重新连接到主机, 因此程序将回到初始化步骤(步骤 1 ) 000847 开始执行。 初始化操作完成后, 在检测设备切换标志的步驟 2中, 检测到的 设备切换标志已经为 "0", 经步骤 3后, 应进行步驟 10。 在步骤 10中, 所 述半导体存储装置内的微处理器一方面要将设备切换标志重新修改为第一 预定值例如 "1", 以便将来再次使用该半导体存储装置来激活操作系统的自 动执行机制; 另一方面, 将当前设备类型标志由光盘驱动器设为磁盘, 其目 的是要使该半导体存储装置进入到其常规的存储功能。 如图 2所示,在接到 操作系统对新连接设备的问询命令时(步骤 11 ), 半导体存储装置根据当前 设备类型标志应答为磁盘。 这样, 操作系统将不会激活自动执行机制, 而是 直接进入该半导体存储装置的常规存储功能, 完成了设备切换动作。
通过当前设备类型标志与设备切换标志的设置,本实施例实现了将半导 体存储装置连接主机后, 光盘驱动器与磁盘类型的切换, 也就实现了激活自 动执行机制和回到常规存储功能的切换。
上述设备切换标志用于在设备切换过程中起导向作用,设备切换过程根 据该设备切换标志的不同值来选择执行分支程序,该设备切换标志的第一和 第二预定值可以是任何一对字符、数值或字符与数值的结合,例如 "1"和" 0", "光盘驱动器 "和"移动磁盘"等, 只要设备切换过程可以根据该设备切换标志 的值来选择执行不同的分支程序即可。
本实施例中的自动执行和设备类型切换流程同样适用于前文所述的笫 二类操作系统, 既支持本地磁盘又支持光盘自动执行的操作系统, 包括 WINDOWS 2000, WINDOWS ME等。这类操作系统对光盘驱动器同样没有 设置存储功能。 如果将半导体存储装置模拟为光盘驱动器,也需要通过上述 常规存储功能切换过程来实现自动执行机制到常规存储功能的切换。
在上述流程中, 到步骤 6为止,都只是将半导体存储装置模拟为光盘驱 动器,操作系统认为半导体存储装置是一个未插入光盘的光盘驱动器,还不 会进行自动执行操作。 进一步的激活操作由自动执行过程(步骤 7 ) 完成。 如图 3, 示出了当一个半导体存储装置模拟为有光盘插入的光盘驱动器时激 活操作系统自动执行机制的流程。此处将前述自动执行和常规存储功能切换 的流程(如图 2所示)称为主流程, 而此处的自动执行流程作为前述主流程 的分流程。
操作系统在识别到有光盘驱动器连接后,会向设备发出问询命令检查有 无光盘插入(步骤 1 )。 根据操作系统发出的问询命令, 可以进一步判断操 作系统类型(步骤 2 )。 例如, 如果操作系统先发出 READ CAPACITY命令, 可知操作系统为 WINDOWS 2000或 WINDOWS XP; 如果操作系统先发出 MODE SENSE命令, 可知操作系统为 WINDOWS 9X或 WINDOWS ME。 根据操作系统的不同, 本领域普通技术人员可知,接下来对命令的应答处理 也略有不同。 为了模拟光盘插入光盘驱动器的动作,使操作系统读取半导体 存储装置中的文件, 需要进行延时处理(步驟 3 )。 经过一段时间的延时, 在操作系统发出设备问询命令时,应答介质改变,光盘已经准备好(步驟 4 ), 可以使操作系统读取半导体存储装置中的数据,根据自动执行机制来寻找自 动执行配置文件。如果在半导体存储装置没有找到自动执行配置文件(步骤 5 ), 则操作系统自动跳出自动执行过程。 如果找到自动执行配置文件, 操作 系统将读取该自动执行配置文件中的信息,根据该信息寻找所指向的指定文 件 (步骤 6 )。 如果根据自动执行配置文件找不到指定文件 (步骤 7 ), 则跳 出自动执行过程。 如果找到指定文件, 则操作系统打开并执行指定文件(步 骤 8 ), 同时退出自动执行过程。
在上述自动执行过程中, 指定文件的执行与设备切换过程是独立进行 的。指定文件可能是执行完毕后自动结束,也可能是需要在用户干预下结束, 其执行所需的时间是不固定的。如果在半导体存储装置上的指定文件尚未执 行结束时就发生了设备切换动作, 将半导体存储装置复位(重新启动)后重 新配置, 会造成指定文件执行中断, 甚至产生蓝屏的现象。 为了避免这种异 常现象出现,需要将参与自动执行的文件复制到主机硬盘上再执行硬盘上的 指定文件副本, 这样, 半导体存储装置的重新启动操作将不会影响指定文件 副本的执行。 根据这一思想, 提出了一种改进的自动执行过程方案,即实施 例 3。 图 4示出了该方案。
为了保证指定文件的正常运行, 要在所连接到主机上的半导体存储装置中 预置一个可执行程序 (以下统称为自动执行程序),操作系统打开该半导体存储 装置上的自动执行配置文件, 该自动执行程序可以自动执行如下动作: 负责通 过预定路径查找到所述待执行的指定文件,并将该指定文件复制到本地硬盘上、 发出复位命令使半导体存储装置复位以返回主流程以及其他容错处理。 该自动 执行程序还复制自身以及指定文件到主机硬盘上,然后调用指定文件副本执行。 在指定文件副本开始执行后, 发出半导体存储装置复位命令。 使该自动执行程 序指向指定文件; 并使自动执行配置文件指向该自动执行程序。
所迷自动执行程序通过预定路径查找指定文件的方式, 可以通过一个预先 定义的配置文件进行: 该配置文件中保存有所述指定文件的路径、 文件名、 文 件类型等信息, 自动执行程序找到该配置文件后, 读取该配置文件内容, 根据 配置文件提供的路径等信息找到指定文件。 还可通过自动执行程序自身直接耷 找到指定文件: 根据用户对指定文件的指定过程, 在自动执行程序中包含该指 定文件的路径、 文件名、 文件类型等信息, 自动执行程序可根据上述信息直接 找出指定文件。
如图 4, 改良后的自动执行流程前 4步骤与改良前相同, 都是根据操作 系统的问询命令判断操作系统类型并进行延时处理。在第 5步,操作系统打 开半导体存储装置上的自动执行配置文件后,根据该自动执行配置文件中的 指定地址和文件名等信息找出自动执行程序 (步驟 6 ), 操作系统将根据自 动执行机制运行该自动执行程序。 自动执行程序进一步根据指定地址找出指 定文件, 并将自身和指定文件复制到主机硬盘上 (步骤 7 )。 此时共有两份 相同的文件: 一份是在自动执行程序原本和指定文件原本, 另一份是在主机 硬盘上的自动执行程序副本和指定文件副本。
自动执行程序原本调用主机硬盘上的自动执行程序副本(步驟 8 ), 使 该自动执行程序副本运行(步驟 9 )后, 自动执行程序原本结束运行, 半导 体存储装置等待由自动执行程序副本发来的复位命令(步驟 13 )。
自动执行程序副本调用主机硬盘上的指定文件副本(步驟 10 ), 使该指 定文件副本执行(步骤 11 )。 调用指定文件副本成功后, 自动执行程序副本 向半导体存储装置发出复位命令(步骤 12 ), 提示开始进行设备切换操作。 半导体存储装置接到该复位命令后(步骤 14 )返回主流程。 结合附图 2, 自 动执行过程将返回到图 2所示流程的节点①处。再设置设备类型标志为第二 预定值例如 "0" (步驟 8 ), 进行半导体存储装置的重新启动和切换过程。
由以上的操作流程可以得出,为保证指定文件在半导体存储装置进行设 备切换过程中仍能正常执行,需要保证真正执行的指定文件位于半导体存储 装置以外的位置, 该位置可以是主机硬盘上, 也可以是主机的其他外部存储 设备如光盘上, 或者可以是与主机建立连接的网络上。 如果自动执行配置文 件指定的自动执行程序和 /或指定文件位于半导体存储装置以外, 那么不需 要将指定文件复制到主机硬盘, 就可以直接执行, 不会因设备切换而影响指 定文件的执行。
附图 4中, 步骤 10和 11是由操作系统控制指定文件进行的, 与本发明 的自动执行过程的进展无关, 故用虚线框示出。
在上述实施例中,在调用指定文件副本成功后, 由自动执行程序副本向 半导体存储装置发出复位命令; 对于支持多用户的主机操作系统而言, 只有 以系统管理员身份登入主机,运行该指定文件才能发出复位命令, 其他非管 理员用户将不能够由自动执行程序副本向半导体存储装置发出复位命令,这 样会造成设备切换操作无法启动。
为解决上述问题,本发明提出了又一实施例, 本实施例采用计时触发的 方式向半导体存储装置发出复位命令, 可支持操作系统多用户的使用。 本实 施例中同样使用如图 2所示的主流程来实现模拟光盘驱动器、切换到半导体 存储装置常规存储功能。 本实施例针对主流程中, 自动执行过程(步骤 7 ) 的分流程结合图 5进行说明: 如图 5, 改良后的自动执行流程前 4步骤与改良前相同, 都是根据操作 系统的问询命令判断操作系统类型并进行延时处理。在笫 5步,加入计时步 骤 13 , 该计时步骤将一直持续直至到达领定的时间长度, 即到达预定计时 值。 第 6、 7、 8、 9步骤与上一实施例类似, 都是操作系统根据半导体存储 装置上的自动执行配置文件找出自动执行程序,运行该自动执行程序。 自动 执行程序进一步找出指定文件, 并将自身和指定文件复制到主机硬盘上。 自 动执行程序原本调用执行自动执行程序副本, 自动执行程序原本结束运行。
在步骤 10, 自动执行程序副本调用主机硬盘上的指定文件副本, 使该 指定文件副本执行 (步骤 11 )。 调用指定文件副本成功后自动执行程序副本 终止运行(步骤 12 )。
另一方面, 步骤 13所示的计时一直进行, 直到到达预定计时值 (步骤 14 )。 此时计时程序向半导体存储装置发出复位命令(步骤 15 ), 然后返回 主流程。
结合附图 2, 自动执行过程将返回到图 2所示流程的节点①处。 再设置 设备类型标志为第二预定值例如" 0" (步驟 8 ), 进行半导体存储装置的重新 启动和切换过程。
上述方法中, 预定计时值应不小于执行步骤 5到步驟 11所需的时间, 即从操作系统打开自动执行配置文件到指定文件副本执行的总时间,保证复 位命令是在指定文件副本执行后发出。 通常情况下预定计时值与指定文件、 自动执行程序的文件尺寸以及主机系统和半导体存储装置的性能有关,该预 定计时值的确定可由用户进行, 也可通过专用软件和 /或程序指定。
本实施例中通过计时触发复位命令的方法可与上一实施例中通过翕动 执行程序发出复位命令的方法结合使用,也可单独使用;结合使用的情况下, 如果自动执行程序未能成功发出复位命令, 而计时已到达预定计时值, 则由 计时程序发出复位命令,可提高自动执行机制的稳定性和可靠性。除此之外, 还可通过开关来手动触发复位命令。
附图 5中, 步骤 10和 11是由操作系统控制指定文件进行的, 与本发明 的自动执行过程的进展无关, 故用虚线框示出。
由以上的操作流程可以得出,为保证指定文件在半导体存储装置进行设 备切换过程中仍能正常执行,需要保证真正执行的指定文件位于半导体存储 装置以外的位置,该位置可以是主机硬盘上, 也可以是主机的其他外部存储 设备如光盘上, 或者可以是与主机建立连接的网络上。 如果自动执行配置文 件指定的自动执行程序和 /或指定文件位于半导体存储装置以外, 那么不需 要将指定文件复制到主机硬盘, 就可以直接执行, 不会因设备切换而影响指 定文件的执行。 至此为止,上述实施例大多是将半导体存储装置先后作为两种不同设备 类型的设备连接到主机并分別进行数据处理。 实际上根据有关协议,还可将 半导体存储装置作为两个或两个以上类型的设备同时与主机相连接,主机或 用户对两个或两个以上的设备同时进行对应设备类型的数据处理而不需要 任何方式的切换。
例如在操作系统询问设备类型时,将半导体存储装置应答为同时具有光 盘驱动器和移动磁盘两个设备, 所述主机对这两个设备分别进行配置、装载 驱动程序等处理,在主机操作系统中产生两个盘符:在光盘驱动器设备方面, 半导体存储装置模拟有光盘插入的光盘驱动器,激活操作系统的自动执行机 制,从而使指定文件自动执行,还可读取设备中的数据甚至根据模拟光盘驱 动器类型的不同, 进行数据写入、 刻录等操作; 而移动磁盘方面, 主机读取 半导体存储装置的文件系统,根据用户的指令对半导体存储装置进行移动磁 盘设备类型的操作例如读、 写数据、 格式化等等, 这两个设备的操作互相独 立, 并不需要切换过程。 对于每个设备的容量等信息, 可由用户手动或通过 程序指定, 也可由半导体存储装置自动指定。
在使用本发明方法实现半导体存储装置内文件的自动执行时,可根据需 要结合加密机制, 对半导体存储装置内的存储空间或文件进行加密; 也可以 通过软件实现自动执行配置文件的有限次执行或有限时执行。例如当自动执 行配置文件指定要执行的指定文件是某软件程序,那么该指定文件可以记录 首次使用的日期, 在该软件程序使用到达预定的使用期限时,提示用户进行 相应操作, 否则软件程序将不再可用。
本发明方法中,可通过各种现有的自动执行配置文件编辑软件来进行对 指定文件的指定过程。 用户可以通过这类软件, 在自动执行配置文件中加入 指定文件的指定地址等信息,再将该自动执行配置文件保存在半导体存储装 置中, 从而实现对指定文件的指定。
综上所述, 本发明的原理在于半导体存储装置通过对操作系统的应答, 激活操作系统预定的自动执行机制,由该机制控制半导体存储装置中自动执 行配置文件, 进而实现指定文件的自动执行功能; 结合半导体存储装置原有 的常规存储功能, 同时实现了半导体存储装置中文件的自动执行和存储功 能。 本发明提供的方法适用于多种操作系统, 多种半导体存储装置, 并且对 于参与自动执行的文件存放地址没有特殊限制,加强了半导体存储装置的应 用功能, 拓宽半导体存储装置的应用范围。
不偏离本发明思想的对本发明技术方案的各种改型将落入本发明权利 要求所限定的范围中。
