Description

可切换操作系统的电脑系统Computer system with switchable operating system

技术领域technical field

本发明涉及一种电脑系统，特别涉及一种可切换操作系统的电脑系统。The invention relates to a computer system, in particular to a computer system with a switchable operating system.

背景技术Background technique

请参考图1，图1为已知电脑系统10的示意图。电脑系统10是一个人数字助理(personal data assistants，PDA)。一般来说，个人数字助理10是一种非常易于携带且已普遍使用的电脑系统，它可提供使用者诸如行程管理、数据输入及储存等功能，且因个人数字助理10本身易于携带的特性，使用者随时可利用它来记录一些数据，而这特性对于需机动性地处理电脑数据的使用者(如销售员、生产线管理者)来说实在是非常方便。但是，因为个人数字助理10本身无法提供较大数据储存空间来存放较多的程序，所以当个人数字助理10开机时，同时间内其可利用的程序非常有限。此外，因个人数字助理10的硬件是经过特别设计的，所以必须执行特定的操作系统才能运作，也因而个人数字助理10并无法被执行在其他操作系统之下，更进而无法执行为其他操作系统所设计的程序。以目前市场占有率最高而由3COM公司所生产的Palm系列的个人数字助理Palm III、IV或V来举例说明，Palm III、IV或V本身用来存放程序的储存空间通常为8M bytes，而以如此有限的数据储存空间来说，所能存放的程序会非常有限，因而同一时间内使用者所能执行的程序也不可能太多。此外，Palm系列的个人数字助理必须执行特别为其所设计的操作系统才能运作，因此并无法在其他操作系统(如：Microsoft Windows NT)下运作，更无法执行为其他操作系统所设计的程序(如：MicrosoftOffice)，所以其所能提供的功能可说是受到了相当大的限制。Please refer to FIG. 1 , which is a schematic diagram of a known computer system 10 . Computer system 10 is a personal data assistant (personal data assistants, PDA). Generally speaking, the personal digital assistant 10 is a computer system that is very easy to carry and has been widely used. It can provide users with functions such as schedule management, data input and storage, and because the personal digital assistant 10 itself is easy to carry, Users can use it to record some data at any time, and this feature is very convenient for users (such as salespersons and production line managers) who need to deal with computer data flexibly. However, because the personal digital assistant 10 itself cannot provide large data storage space to store more programs, so when the personal digital assistant 10 is turned on, the available programs at the same time are very limited. In addition, because the hardware of the personal digital assistant 10 is specially designed, it must execute a specific operating system to operate, and thus the personal digital assistant 10 cannot be executed under other operating systems, and furthermore cannot be executed as other operating systems. The designed program. Take the personal digital assistant Palm III, IV or V of the Palm series produced by 3COM Company with the highest market share at present as an example. The storage space used for storing programs by Palm III, IV or V itself is usually 8M bytes. For such a limited data storage space, the programs that can be stored will be very limited, so it is impossible for the user to execute too many programs at the same time. In addition, the personal digital assistants of the Palm series must execute the operating system specially designed for them to operate, so they cannot operate under other operating systems (such as: Microsoft Windows NT), let alone execute programs designed for other operating systems ( Such as: Microsoft Office), so the functions it can provide can be said to be quite limited.

请参考图2，图2为另一种已知电脑系统20的示意图。电脑系统20是一种个人电脑，其包含有一主机22以及一显示器24。一般来说个人电脑20可用来储存程序的数据储存装置非常多，如：硬盘、数字影音光碟机(DVD)等，故与个人数字助理10相比较之下，个人电脑20有较大的数据储存空间可用来存放较多的程序，并因此能提供较多的功能给使用者。但是，因为个人电脑20体积较个人数字助理庞大，重量也较重，故并不利于携带，且即使以目前很流行的笔记本电脑来与一般个人数字助理作比较，也是较难携带并且较耗电，而这一点对于电脑携带性非常挑剔的使用者来说，实无法令其满意。Please refer to FIG. 2 , which is a schematic diagram of another known computer system 20 . The computer system 20 is a personal computer, which includes a host 22 and a display 24 . Generally speaking, there are many data storage devices that the personal computer 20 can be used to store programs, such as: hard disk, digital video disc player (DVD), etc., so compared with the personal digital assistant 10, the personal computer 20 has a larger data storage capacity. The space can be used to store more programs, and thus can provide more functions to users. However, because the personal computer 20 is larger and heavier than the personal digital assistant, it is not conducive to portability, and even if the currently popular notebook computer is compared with the general personal digital assistant, it is also difficult to carry and consumes more power. , and this point is really unsatisfactory for users who are very picky about computer portability.

请参考图3，图3为图1个人数字助理10与图2电脑系统20连接时的示意图。当使用者因本身的工作需求而须同时拥有个人数字助理10的便利性以及个人电脑20的强大功能时，通常会同时购置个人数字助理10及个人电脑20，以使其可以依据其工作状况来挑选合适的机器处理工作，比如说，当使用者须机动性地处理电脑数据时，可先将数据输入个人数字助理10中，而当使用者须执行较庞大的程序来完成工作时，则可借助个人电脑20来执行。但因使用者须同时购置个人数字助理10和个人电脑20，而无疑地这会使使用者的开销增加，且除此之外，因个人电脑20只被视为个人数字助理10的数据来源，而个人数字助理10亦无法利用庞大的个人电脑20的资源及运算能力，两者的系统资源并没有有效地被结合在一起，造成了使用者使用时的不便。另外，因个人数字助理10包含有一显示屏幕12，而个人电脑20亦包含一显示装置24，因此也必定会形成显示装置的重复配置情形。Please refer to FIG. 3 , which is a schematic diagram of the connection between the PDA 10 of FIG. 1 and the computer system 20 of FIG. 2 . When the user must have the convenience of the personal digital assistant 10 and the powerful function of the personal computer 20 at the same time because of his own work requirements, he usually purchases the personal digital assistant 10 and the personal computer 20 at the same time, so that it can be used according to its working conditions. Select the appropriate machine to handle the work, for example, when the user needs to process computer data flexibly, the data can be input into the personal digital assistant 10 first, and when the user needs to execute a larger program to complete the work, the user can It is carried out by means of a personal computer 20 . But because the user has to purchase the personal digital assistant 10 and the personal computer 20 at the same time, it will undoubtedly increase the user's expenses, and in addition, because the personal computer 20 is only regarded as the data source of the personal digital assistant 10, And the personal digital assistant 10 also cannot utilize the resources and computing power of the huge personal computer 20, and the system resources of the two are not effectively combined together, causing inconvenience to the user when using it. In addition, since the personal digital assistant 10 includes a display screen 12 and the personal computer 20 also includes a display device 24 , there must be a situation of repeated configuration of the display devices.

请参考图4及图5，图4为本发明电脑系统30其便携式电脑40与扩充装置70分离时的示意图。图5为图4便携式电脑40与扩充装置70连接时的示意图。电脑系统30包含有一便携式电脑40及一扩充装置70。其中，便携式电脑40是一个人数字助理(PDA)，而扩充装置70为一基台(docking station)，因此便携式电脑40可平稳地安置于扩充装置70之上。Please refer to FIG. 4 and FIG. 5 . FIG. 4 is a schematic diagram of the computer system 30 of the present invention when the portable computer 40 is separated from the expansion device 70 . FIG. 5 is a schematic diagram of the connection between the portable computer 40 of FIG. 4 and the expansion device 70 . The computer system 30 includes a portable computer 40 and an expansion device 70 . Wherein, the portable computer 40 is a personal digital assistant (PDA), and the expansion device 70 is a base station (docking station), so the portable computer 40 can be placed on the expansion device 70 stably.

请参考图6，图6为图4电脑系统30的功能方块图。便携式电脑40包含有一显示装置42，用来显示信息给一使用者，一第一储存装置44，用来储存一第一操作系统52、一第一操作系统载入程序54及一第二操作系统载入程序56，一处理电路46，用来执行第一操作系统52，一连接器48，用来使便携式电脑40可电连接于扩充装置70。当便携式电脑40开机时，处理电路46会先执行第一操作系统载入程序54，以完成相关的系统检查以及初始化动作。此外，扩充装置70包含有一第二储存装置72，用来储存一第二操作系统74及至少一应用程序78。其中，便携式电脑40可与扩充装置70分离，并可通过连接器48与扩充装置70连结。当便携式电脑40与扩充装置70分离时(如图4所示)，处理电路46会执行第一操作系统52而使便携式电脑40可独立运作，因此使用者可将便携式电脑40携带在身边，当需要使用时即可拿出来使用。例如：一工厂库存管理员即可在盘点库存时利用便携式电脑40输入盘点的库存量，而另一位货物调度员可利用便携式电脑40随时输入货物的进出数据。除此之外，当便携式电脑40通过连接器48与扩充装置70连接时(如图5所示)，处理电路46可选择性地执行第二操作系统载入程序56以载入并执行第二操作系统74，并且停止执行第一操作系统52，使用者进而可在第二操作系统74下执行应用程序78。例如：当库存管理员或货物调度员输入完数据后，可将便携式电脑40与扩充装置70连接，并在第二操作系统74之下执行应用程序78，以将之前所输入的数据再做进一步地处理。Please refer to FIG. 6 , which is a functional block diagram of the computer system 30 in FIG. 4 . The portable computer 40 includes a display device 42 for displaying information to a user, a first storage device 44 for storing a first operating system 52, a first operating system loader 54 and a second operating system A loading program 56 , a processing circuit 46 for executing the first operating system 52 , and a connector 48 for electrically connecting the portable computer 40 to the expansion device 70 . When the portable computer 40 is turned on, the processing circuit 46 first executes the first operating system loading program 54 to complete related system checking and initialization actions. In addition, the expansion device 70 includes a second storage device 72 for storing a second operating system 74 and at least one application program 78 . Wherein, the portable computer 40 can be separated from the expansion device 70 and can be connected with the expansion device 70 through the connector 48 . When the portable computer 40 is separated from the expansion device 70 (as shown in FIG. 4 ), the processing circuit 46 will execute the first operating system 52 so that the portable computer 40 can operate independently, so the user can carry the portable computer 40 with him. It can be taken out when needed. For example: a factory inventory manager can utilize the portable computer 40 to input the stock quantity of inventory when taking inventory, and another cargo dispatcher can utilize the portable computer 40 to input the incoming and outgoing data of goods at any time. In addition, when the portable computer 40 is connected to the expansion device 70 through the connector 48 (as shown in FIG. 5 ), the processing circuit 46 can selectively execute the second operating system loader 56 to load and execute the second operating system. The operating system 74 stops executing the first operating system 52 , and the user can then execute the application program 78 under the second operating system 74 . For example: after the inventory manager or the cargo dispatcher has finished inputting the data, the portable computer 40 can be connected with the expansion device 70, and the application program 78 can be executed under the second operating system 74, so that the previously input data can be further processed. deal with it.

本实施例中，第一储存装置44是一快闪存储器(flash memory)，其内储存有一依据Unix核心程序所架构的第一操作系统52，而处理电路46包含有一处理器62。当便携式电脑40与扩充装置70分离时，处理电路46会通过处理器62来执行第一操作系统52以处理便携式电脑40的相关运算工作，而当便携式电脑40通过连接器48与扩充装置70连接时，处理电路46可选择性地执行第二操作系统载入程序56以载入并执行第二操作系统74，而使得处理电路46所执行的操作系统可从第一操作系统52切换到第二操作系统74。此外，第二操作系统74还提供一系统文件读取功能，使使用者可在处理电路46执行第二操作系统74时读取第一操作系统52储存在第一储存装置44内的文件58，而如此一来，文件58中所储存的数据即可被各种操作系统所读取并加以利用。附带说明的，在本实施例中，第二操作系统74所提供的系统文件读取功能是内建于第二操作系统74，然而，若使用者欲在处理电路46执行第二操作系统74时来读取第一储存装置44内的文件58，除了如上面所述，可通过第二操作系统74来读取之外，还可通过执行某一应用程序78来达成，例如可将某一软件公司所设计的程序储存在第二储存装置72中，使用者可在第二操作系统74下执行此一程序来读取第一储存装置44中的文件58。In this embodiment, the first storage device 44 is a flash memory, which stores a first operating system 52 based on the Unix kernel program, and the processing circuit 46 includes a processor 62 . When the portable computer 40 is separated from the expansion device 70, the processing circuit 46 will execute the first operating system 52 through the processor 62 to handle the relevant computing work of the portable computer 40; At this time, the processing circuit 46 can selectively execute the second operating system loader 56 to load and execute the second operating system 74, so that the operating system executed by the processing circuit 46 can be switched from the first operating system 52 to the second operating system. operating system74. In addition, the second operating system 74 also provides a system file reading function, so that the user can read the file 58 stored in the first storage device 44 by the first operating system 52 when the processing circuit 46 executes the second operating system 74, In this way, the data stored in the file 58 can be read and utilized by various operating systems. Incidentally, in this embodiment, the system file reading function provided by the second operating system 74 is built in the second operating system 74, however, if the user wants to execute the second operating system 74 on the processing circuit 46 To read the file 58 in the first storage device 44, in addition to being read by the second operating system 74 as described above, it can also be achieved by executing a certain application program 78, for example, a certain software can be The program designed by the company is stored in the second storage device 72 , and the user can execute this program under the second operating system 74 to read the file 58 in the first storage device 44 .

在此特别指出，当便携式电脑40连接至扩充装置70时，便携式电脑40不必重新开机即可通过处理电路46以执行第二操作系统载入程序56的方式，将处理电路46所执行的操作系统从第一操作系统52转换成第二操作系统74，而当处理电路46顺利地执行第二操作系统74后，即会停止执行第一操作系统52。当然，当处理电路46执行第二操作系统74时，若便携式电脑40与扩充装置70之间的电连接被切断，便携式电脑40亦不须重新开机，处理电路46会再次执行第二操作系统载入程序56来载入并执行第一操作系统52，并且停止执行第二操作系统74。因此当便携式电脑40与扩充装置70分离后，便携式电脑40即可通过处理电路46所执行第一操作系统52而继续运作。当然，电脑系统30除了可设计成便携式电脑40不必重新开机即可切换操作系统之外，电脑系统30亦可设计成当便携式电脑40于切换操作系统时，需重新开机的型态。若便携式电脑40被设计成需重新开机才可切换操作系统的话，当便携式电脑40开机时，处理电路46会先执行储存于第一储存装置44的开机磁区中的第一操作系统载入程序54，此后第一操作系统载入程序54会执行堆叠初始化及系统检测等动作并载入第二操作系统载入程序56。当第二操作系统载入程序56被执行后，第二操作系统载入程序56会等待使用者的输入，以决定是要载入快闪存储器44中的第一操作系统52，或是载入储存在第二储存装置中的第二操作系统74。如此一来，使用者即可选择其所欲执行的操作系统。It is particularly pointed out here that when the portable computer 40 is connected to the expansion device 70, the portable computer 40 can use the processing circuit 46 to execute the second operating system loading program 56, and the operating system executed by the processing circuit 46 does not need to be restarted. Switch from the first operating system 52 to the second operating system 74 , and when the processing circuit 46 successfully executes the second operating system 74 , it stops executing the first operating system 52 . Of course, when the processing circuit 46 executes the second operating system 74, if the electrical connection between the portable computer 40 and the expansion device 70 is cut off, the portable computer 40 does not need to be restarted, and the processing circuit 46 will execute the second operating system again. The program 56 is used to load and execute the first operating system 52, and stop executing the second operating system 74. Therefore, when the portable computer 40 is separated from the expansion device 70 , the portable computer 40 can continue to operate through the processing circuit 46 executing the first operating system 52 .
