Description
本發明係有關於一種資料拴鎖裝置及其啟動電子裝置的方法，其係尤指一種具啟動電子裝置之資料拴鎖裝置及其啟動電子裝置的方法。The invention relates to a data shackle device and a method for starting the same, which particularly relates to a data shackle device with a starter electronic device and a method for starting the same.
按，半導體儲存裝置是可以儲存資料的一種半導體晶片，此類型的半導體晶片可以接受外部的寫入命令與資料，並將資料寫入儲存於晶片；該類型的晶片也可以接收外部的讀取命令來讀取儲存在晶片上的資料，並向外部輸出資料；該類型的晶片還支援其他命令如抹除、重定等。這類型半導體儲存裝置包括但不限於一快閃記憶體(Flash memory)、EEPROM、FRAM、DRAM、SRAM、SDRAM或MRAM。與傳統的磁、光介質等儲存介質相比，半導體儲存裝置具有體積小、重量輕、容量大、可靠性高、耗電量小等優點，而且不需要特定的機械裝置來驅動。例如現今半導體儲存裝置可無驅動器、無須開機；存取速度快，容量大大超過軟碟；體積小，攜帶方便，不易損壞。
如此，電腦科技發展，人與人之間的資訊傳遞頻繁，所以隨身快閃儲存裝置成為每個人必備的電子產品。而現今市面上許多電子產品亦提供了隨身快閃儲存裝置的介面可供使用，現今的儲存裝置可分割成一個或二個以上的儲存空間供使用者，以增加使用上的便利性。
然而，現在傳統軟碟機和磁片的作用越來越小，特別是當快閃儲存裝置發明以後，資料的交流均可不依賴軟碟機和磁片。但當今使用電腦的人們卻發現仍然離不開軟碟機和磁片，其原因之一是上述快閃儲存裝置無法支援電腦啟動，當電腦系統被病毒破壞或被病毒感然時需要一張乾淨的啟動磁片來從BIOS(Basic Input and Output System，基本輸入輸出系統)重新啟動電腦。一台主機採用內置式軟碟機，以備系統啟動之用，這樣一來增加了主機系統的體積和重量，以及成本。雖然目前快閃儲存裝置例如DiskOnChip可以支援電腦啟動，但因為它內置於主機系統，不能熱拔插和移動，當主機被病毒感染破壞時，無法通過DiskOnChip啟動系統，從而限制了其應用範圍。
因此，如何針對上述問題而提出一種新穎具有啟動電子裝置功能之資料拴鎖裝置及其啟動電子裝置的方法，其可增加資料拴鎖裝置在應用層面上能更廣泛和更方便，使可解決上述之問題。Press, the semiconductor storage device is a semiconductor wafer that can store data. This type of semiconductor wafer can accept external write commands and data, and write data to the wafer; this type of wafer can also receive external read commands. To read the data stored on the wafer and output the data to the outside; this type of chip also supports other commands such as erasing, re-setting, and the like. Semiconductor storage devices of this type include, but are not limited to, a flash memory, EEPROM, FRAM, DRAM, SRAM, SDRAM, or MRAM. Compared with conventional storage media such as magnetic and optical media, the semiconductor storage device has the advantages of small size, light weight, large capacity, high reliability, low power consumption, and the like, and does not require a specific mechanical device to drive. For example, today's semiconductor storage devices can be driven without a boot, have a fast access speed, and have a capacity that greatly exceeds that of a floppy disk; they are small in size, easy to carry, and not easily damaged.
In this way, the development of computer technology and frequent information transmission between people, so the flash memory storage device becomes an essential electronic product for everyone. Many electronic products on the market today also provide an interface for portable flash storage devices. Today's storage devices can be divided into one or more storage spaces for users to increase the convenience of use.
However, the role of the conventional floppy disk drive and the magnetic disk is becoming smaller and smaller, especially after the invention of the flash memory device, the data exchange can be independent of the floppy disk drive and the magnetic disk. However, people who use computers today find that they are still inseparable from floppy disks and magnetic disks. One of the reasons is that the flash memory device cannot support computer startup. When the computer system is damaged by viruses or is affected by viruses, it needs a clean one. Start the disk to restart the computer from the BIOS (Basic Input and Output System). A host computer uses a built-in floppy disk drive for system startup, which increases the size and weight of the host system, as well as the cost. Although the current flash storage device, such as DiskOnChip, can support computer startup, because it is built into the host system, it cannot be hot plugged and moved. When the host is damaged by a virus, the system cannot be booted through DiskOnChip, thereby limiting its application range.
Therefore, how to solve the above problems and propose a novel data shackle device having the function of starting an electronic device and a method for starting the same, which can increase the data shackle device can be more extensive and convenient at the application level, so that the above can be solved. The problem.

茲為使 貴審查委員對本發明之結構特徵及所達成之功效有更進一步之瞭解與認識，謹佐以較佳之實施例及配合詳細之說明，說明如後：
請參閱第一圖，其為本發明之具啟動電子裝置之資料拴鎖裝置之一實施例的方塊圖。如圖所示，本發明之資料拴鎖裝置1為一可攜式資料拴鎖裝置，例如半導體儲存裝置(Flash memory)，隨身碟或行動硬碟等。本發明主要是藉由可攜式資料拴鎖裝置儲存開機碼(Boot code)並用以來對電子裝置進行開機，以達到讓使用者能更廣泛和更方便地使用資料拴鎖裝置1。以下係針對如何利用可攜式資料拴鎖裝置來對電子裝置進行開機程序而進行說明。
本發明之資料拴鎖裝置1包含至少一儲存單元10與一控制單元20。儲存單元10包含複數儲存空間12，14，16，該些儲存空間12，14，16之其中之一儲存至少一開機碼(Boot code)，於此實施例中，儲存單元10之儲存空間16儲存開機碼與其他系統資料(System info)。控制單元20耦接儲存單元10，用以存取儲存單元10之該些儲存空間12，14，16所儲存的資料，並在資料拴鎖裝置1連接一電子裝置30(例如數位相機、印表機或翻譯機等)時，控制單元20宣告資料拴鎖裝置1為一主控端(Host)，並控制單元20讀取並傳送儲存單元10之開機碼至電子裝置30，以開機電子裝置30。
於本實施例中，本發明之資料拴鎖裝置1具有OTG(On The Go)功能，即當資料拴鎖裝置1連接電子裝置30時，控制單元20會向電子裝置30宣告資料拴鎖裝置1為主控端(Host)，而透過endpoint0執行資料傳輸，以及執行列舉(enumerate)動作使電子裝置30為裝置端，所以，資料拴鎖裝置1之控制單元20可以讀取電子裝置之一描述(descriptor)資訊與電子裝置30的一相關資訊，而得知儲存單元10之儲存空間16所儲存之開機碼是否為電子裝置30的開機碼，若儲存空間16所儲存之開機碼符合電子裝置30的開機碼時，控制單元20則會讀取儲存空間16所儲存之開機碼，並傳送開機碼至電子裝置30，使電子裝置30可執行開機碼而啟動。如此，本發明藉由資料拴鎖裝置1連接電子裝置30時，資料拴鎖裝置1之身分轉變為主控端，並讀取且傳送本身所儲存之開機碼至電子裝置30而啟動電子裝置30，以達到讓使用者能更廣泛和更方便地使用資料拴鎖裝置1。
此外，儲存單元10可儲存多種不同開機碼，例如儲存單元10可儲存數位相機的開機碼、印表機的開機碼以及翻譯機的開機碼，如此，本發明之資料拴鎖裝置1即可支援數位相機、印表機與翻譯機的開機，即使用者只需要使用一個可攜式的資料拴鎖裝置1即可對數位相機、印表機與翻譯機而進行開機，而不再需要對應數位相機、印表機與翻譯機使用不同的開機軟碟或開機光碟，而讓使用者能更廣泛和更方便地使用資料拴鎖裝置1。
另外，如第一圖所示，本發明之資料拴鎖裝置1與電子裝置30連接時，資料拴鎖裝置1可分為實體端(Physical)與邏輯端(Logical)，即本發明之資料拴鎖裝置1經過一實體與一邏輯間的配對(mapping)機制，而使用者可藉由應用程式或顯示裝置得知資料拴鎖裝置1內部之邏輯區域分為多個儲存空間，儲存空間12，14，16，儲存空間16儲存開機碼與其他系統資料(System info)，即資料拴鎖裝置1內部之邏輯區域為使用者能看見的區域，控制單元20會依據邏輯區域的儲存空間而對應儲存於儲存單元10內。
又，本發明之資料拴鎖裝置1更包含一傳輸介面40，傳輸介面40耦接控制單元20，並用以連接電子裝置30與資料拴鎖裝置1，而傳輸資料和開機碼。其中，傳輸介面40為一通用串列匯流排(Universal Serial Bus，USB)、一小型電腦系統介面(Small Computer System Interface，SCSI)、一AT傳輸介面(AT Attachment，ATA)、一可編程通用輸入輸出(General Purpose Input/Output，GPIO)或一序列周邊介面(Serial Peripheral Interface bus，SPI)。
請一併參閱第二圖，為本發明之資料拴鎖裝置1啟動電子裝置的方法之一實施例的流程圖。如圖所示，本發明之資料拴鎖裝置1啟動電子裝置的方法係先執行步驟S10啟動資料拴鎖裝置1與電子裝置的電源並連接資料拴鎖裝置1與電子裝置30，接著，執行步驟S12判斷電子裝置30執行內部儲存之開機碼(如步驟S14所示)或是執行外部資料拴鎖裝置1中所儲存的開機碼，其中，電子裝置30可以自行確認是載入內部記憶單元(ROM)所儲存之開機碼，還是載入外部資料拴鎖裝置1所儲存之開機碼，當然電子裝置30可以直接設定為載入外部資料拴鎖裝置1儲存之開機碼來啟動。
再者，執行步驟S16資料拴鎖裝置1之控制單元20宣告資料拴鎖裝置1為主控端，而電子裝置30為裝置端，接著執行步驟S18訊號交流(Handshaking)資料拴鎖裝置1與電子裝置30，以資料拴鎖裝置1辨識與匹配電子裝置30，而確認資料拴鎖裝置1所儲存之開機碼符合電子裝置30所需要之開機碼，當資料拴鎖裝置1確認本身所儲存之開機碼不符合電子裝置30所需要之開機碼時，則回到執行步驟S14電子裝置30載入內部記憶單元(ROM)所儲存之開機碼；當資料拴鎖裝置1確認本身所儲存之開機碼符合電子裝置30所需要之開機碼時，則執行步驟S20讀取資料拴鎖裝置1所儲存之開機碼，並執行步驟S22傳送開機碼至電子裝置30。
之後，執行步驟S24電子裝置30執行開機碼而進行啟動程序，其中，資料拴鎖裝置1將開機碼載入電子裝置30後，電子裝置30便會中斷與資料拴鎖裝置1的連結，而執行開機碼進行啟動程序，以避免電子裝置30在執行開機碼的過程中，資料拴鎖裝置1仍繼續傳輸資料至電子裝置30，造成電子裝置啟動失敗。接下來執行步驟S26電子裝置重新列舉(re-enumrate)資料拴鎖裝置1，資料拴鎖裝置1宣告為裝置端，即當電子裝置30完成啟動程序之後，資料拴鎖裝置1之控制單元20則會宣告資料拴鎖裝置1為裝置端，而供電子裝置存取資料之用，之後，執行步驟S28電子裝置存取資料於資料拴鎖裝置1。
請一併參閱第三圖，為本發明之訊號交流資料拴鎖裝置1與電子裝置之步驟的詳細流程圖。如圖所示，在訊號交流資料拴鎖裝置1與電子裝置30之步驟中還包含了資料拴鎖裝置1辨識電子裝置30以及匹配資料拴鎖裝置1與電子裝置以讀取資料拴鎖裝置1所儲存之開機碼。其中，在資料拴鎖裝置1辨識電子裝置30中係先執行步驟S180設定資料拴鎖裝置1與電子裝置之間的一傳輸位址，即資料拴鎖裝置1此時為主控端，所以資料拴鎖裝置1會給電子裝置30一個獨一無二的位址，而作為資料拴鎖裝置1與電子裝置30之後溝通的位址之用，以完成定址的程序。接著執行步驟S182依據傳輸位址取得電子裝置之一描述(descriptor)資訊，即資料拴鎖裝置1之控制單元20會透過傳輸位址而取電子裝置30的描述資訊，其中描述資訊包含了一裝置描述(Device Descriptor)、一配置描述(Configuration Descriptor)、一介面描述(Interface Descriptor)、一端點描述(Endpoint Descriptor)或是一字串描述(String Descriptor)。其中，裝置描述的內容包含USB規格，VID/PID與配置數目；配置描述的內容包含特性與介面個數；介面描述的內容包含裝置類型與規格，端點個數；端點描述的內容包含資料傳輸端點、模式、方向、大小和間隔；字串描述的內容包含文字說明。如此，經過上述的流程，資料拴鎖裝置1即可完成與電子裝置30之間的傳輸辨識。
再者，經過上述之標準傳輸協定(Standard command)的辨識程序之後，即可執行本發明之特定傳輸協定(Vendor command)，而匹配資料拴鎖裝置1與電子裝置30以讀取資料拴鎖裝置1所儲存之開機碼，其包含了執行步驟S184傳送電子裝置之一辨識碼(ID)至資料拴鎖裝置1，即資料拴鎖裝置1之控制單元20會發送命令至電子裝置30，使電子裝置30依據控制單元20所發出的命令而對應輸出辨識碼(ID)，之後，執行步驟S186資料拴鎖裝置1依據辨識碼，得知開機碼符合電子裝置30，以讀取資料拴鎖裝置1所儲存之開機碼，即控制單元20接收辨識碼後，即可得知資料拴鎖裝置1所儲存之開機碼是否為電子裝置30所需要的開機碼，當資料拴鎖裝置1所儲存之開機碼為電子裝置30所需要的開機碼時，而資料拴鎖裝置1會傳送開機碼至電子裝置30，而供電子裝置30執行開機碼而啟動。
請復參閱第一圖，若電子裝置30也儲存一開機碼時，在資料拴鎖裝置1連接電子裝置30時，控制單元20會比較儲存空間16所儲存之開機碼與電子裝置30所儲存之開機碼，以更新電子裝置30之開機碼，即控制單元20可以藉由電子裝置30所傳送至辨識碼而得知電子裝置30內部開機碼的版本，並比較儲存空間16所儲存之開機碼的版本與電子裝置30所儲存之開機碼的版本，當資料拴鎖裝置1所儲存之開機碼的版本是新版本時，則資料拴鎖裝置1會傳送本身所儲存之開機碼的版本至電子裝置30，而更新電子裝置30之開機碼，以達到讓使用者能更廣泛和更方便地使用資料拴鎖裝置1。
再者，在資料拴鎖裝置1連接電子裝置30時，資料拴鎖裝置1會判斷電子裝置30之開機碼之狀態，以在該電子裝置之開機碼損壞時，而傳送儲存空間16之開機碼傳送至電子裝置30，以修復電子裝置30之開機碼，即在電子裝置30也儲存開機碼時，資料拴鎖裝置1可以藉由電子裝置30所傳送至辨識碼而得知電子裝置30內部開機碼的狀態，例如藉由辨識碼的部分位元而可判斷電子裝置30之開機碼之狀態，或是資料拴鎖裝置1可在主控端時，發出命令，要求電子裝置30回傳內部儲存之開機碼的狀態，供資料拴鎖裝置1之控制單元20判斷電子裝置30之開機碼之狀態，當電子裝置之開機碼損壞時，而傳送儲存空間16之開機碼傳送至電子裝置30，以修復電子裝置30之開機碼，以達到讓使用者能更廣泛和更方便地使用資料拴鎖裝置1。。
綜上所述，本發明之具啟動電子裝置之資料拴鎖裝置，其由一資料拴鎖裝置包含複數儲存空間，該些儲存空間之一儲存至少一開機碼，一控制單元用以存取儲存單元之開機碼。本發明之資料拴鎖裝置啟動電子裝置的方法係於連接資料拴鎖裝置與一電子裝置，資料拴鎖裝置宣告為一主機，接著控制單元讀取資料拴鎖裝置之儲存空間所儲存之開機碼，並傳送開機碼至電子裝置而供該電子裝置執行而啟動，以達到讓使用者能更廣泛和更方便地使用資料拴鎖裝置。

惟以上所述者，僅為本發明之一較佳實施例而已，並非用來限定本發明實施之範圍，舉凡依本發明申請專利範圍所述之形狀、構造、特徵及精神所為之均等變化與修飾，均應包括於本發明之申請專利範圍內。In order to provide a better understanding and understanding of the structural features and the achievable effects of the present invention, the preferred embodiments and detailed descriptions are provided as follows:
