Embodiment
Fig. 2 is the system architecture diagram of computer system of the present invention.This figure is a kind of computer system of dynamic access external storage device 20, can dynamically be connected and separate with it by the hot plug action for more than one external storage device 20, it be dynamically to be connected or to separate with connecting interface 22 and input/output control circuit 24 that the dotted line among the figure is promptly represented each external storage device 20.Computer system of the present invention comprises at least: connecting interface 22 is connected with external storage device 20; Input/output control circuit 24 connects and separates for external storage device 20, exports a caution signal 240 when external storage device 20 and its connection status change; System, control circuit 26 is connected with input/output control circuit 24, is used to receive caution signal 240 and exports an interrupt request singal 260 after receiving caution signal 240; Interface control circuit 28 is connected with connecting interface 22, and according to each interface setting value of its internal memory, the transmission standard of control linkage interface 22 and interface specification; CPU (central processing unit) 29, be connected external storage device 20 by connecting interface 22, be used for dynamic access external storage device 20, and it is connected with system, control circuit 26, receive interrupt request singal 260, and after receiving interrupt request singal 260, carry out interrupt service routine (seeing also Fig. 3).
Shown in Figure 2 is the specific embodiment of Computer Systems Organization, and it can be the storage server system of storage great mass of data, and therefore the external storage device 20 that uses is a kind of large-scale memory storages (as disk set).The connecting interface 22 that this storage server system uses is disk drive interface, and disk drive interface can be following any specification: IDE specification, E-IDE specification, ATA specification, ATAPI specification etc.In addition, the input/output control circuit 24 that it had can be super I/O chip, and this chip has more than one general input as input/output port, connects for more than one external storage device 20.Can use South Bridge chip as for 26 of system, control circuits.
Fig. 3 is the process flow diagram of the interrupt service routine that uses of the present invention.Wherein, step 30 is to judge interrupt request singal 260, whether be because of the connection status between input/output control circuit 24 and the external storage device 20 change cause, if, carry out step 32, if not, then to step 34; Step 32 is the number of the external storage device 20 that connected this moment according to input/output control circuit 24 and the configuration combination of each external storage device 20, loads corresponding interface setting value to interface control circuit 28; Step 34 is to finish this interrupt service routine.
Be described further with regard to step 32 at this, and propose specific practice.The interface setting value of interface control circuit 28 internal memories must be looked the number difference of its external storage device that connects 20, and different settings is arranged, can be suitably and the correctly transmission standard and the interface specification of control linkage interface 22.On specific practice, can be under the configuration combination of various external storage devices 20, in operating system environment, pass through PCI implementing procedure or I/O implementing procedure, the content of fetch interface control circuit 28, put out a question blank then in order, again this question blank is placed in the interrupt service routine (ISR) of the present invention's use.Thus, when CPU (central processing unit) 29 execution in step 32, the number of the external storage device 20 that will be connected this moment according to input/output control circuit 24 and the configuration combination of each external storage device 20, this question blank is inquired about, find its corresponding interface setting value, and then the interface setting value is loaded in the interface control circuit 28, reach the purpose of correct control.
Therefore, the present invention can carry out function setting to each chip in the conventional computer system again by Basic Input or Output System (BIOS), do not need all to abandon original Computer Systems Organization, write an interrupt service routine again, carry out interrupt service routine of the present invention (as shown in Figure 3), can reach the hot plug mechanism of memory storage,, have certain progressive and industry applications so that the present invention has a cost is low and implement characteristics such as easy; Have, memory storage directly be inserted or be pulled out to the hot plug function that the present invention has can in start is used, do not need to start shooting again, also saved the inconvenience of opening host housing again; In addition, the present invention has the characteristic of plug and play, as long as the user inserts computer interface with memory storage, operating system will detect this memory storage at once automatically, and load corresponding interface setting value automatically, be available for users to carry out the access of data immediately.Because the present invention has characteristics such as hot plug and plug and play, therefore make things convenient for the user that memory storage is upgraded and expand.
