Description
Technical field
The present invention is relevant for a kind of technology of update calculation machine system data storage data, particularly about a kind of interface arrangement of system data storage of renewal micro controller device.
Background technology
The typical calculation machine can at first carry out the basic start-up routine of system of standard when start at present.In order to reach this basic start-up routine of system, on the motherboard of this computer installation, all be provided with a ROM-BIOS (Basic Input and Output System, be called for short BIOS), and in this ROM-BIOS, store the ROM-BIOS sign indicating number in advance, and this ROM-BIOS sign indicating number includes ROM-BIOS program and system's self test program.So when this computer installation when starting shooting, central processing unit can be by loading and carry out ROM-BIOS program and system's self test program in the ROM-BIOS internal memory.In the present design, central processor is videoed (Shadow) to Installed System Memory with the ROM-BIOS sign indicating number in the ROM-BIOS among this computer installation, and carries out this ROM-BIOS sign indicating number.
Finish after system initially reaches self test program at this computer installation, the operating system that this computer installation just can load and carry out in the hard disk to be installed, and make computer installation enter normal computer operating modes.
Including in the electronic system of micro controller device of micro controller the typical case, mainly is with the control core of micro controller as entire equipment.The running of this micro controller needs the specific peripheral cell of collocation just can reach predetermined purpose.Consult shown in Figure 1ly, it is that a tradition is with the simplified system synoptic diagram of micro controller as the computer installation on basis.As shown in Figure 1, a micro controller device 100 mainly includes a micro controller 11 and is connected in one of this micro controller 11 Installed System Memory 12, a system data storage 13, a data memory device 14.Wherein this system data storage 13 is as the ROM-BIOS (Basic Input and OutputSystem) of this micro controller device 100.
This micro controller device 100 can be a personal computer system or based on the digital device of micro controller, and this system data storage 13 is for being connected in the ROM-BIOS of this micro controller through bridge.This micro controller device 100 can also be the subsystem in the computer system, for example it can be a keyboard controller, and the embedded controller (Embedded Controller) that this micro controller 11 is this keyboard controller, 13 of this system data storages are the keyboard ROM-BIOS (Keyboard BIOS) of this keyboard controller.
In Computer Design now, this ROM-BIOS can ROM (read-only memory), maybe can repeat to override internal memory or flash type internal memory data storing chip components such as (Flash Memory Array Chip) stores the ROM-BIOS sign indicating number, so that computer installation is when start, by central processing unit the ROM-BIOS sign indicating number in the ROM-BIOS is videoed to Installed System Memory, and carry out this ROM-BIOS sign indicating number.
Tradition with the digital device or electronic equipment of micro controller as the basis in, generally can not protect at embedded controller or system data storage, its main cause is because general user can not carry out the operation of Data Update easily.
For example, for the renewal of the keyboard ROM-BIOS in the computer system (Keyboard Basic Inputand Output System), in some situation, promptly can't not deal with problems if do not upgrade this keyboard ROM-BIOS.Under this situation, often have the user accidentally mistake plant product type, and cause version error, model plane No. mistake, and cause the situation that can't start shooting.
Usually when running into above-mentioned unusual condition, the user has to send whole board back to former factory or service broker merchant keeps in repair, changes.No matter and former factory or service broker merchant keep in repair, when changing, the general practice is to take whole board apart, so except unusual trouble, also can be corrupted to the integrality of entire mechanism.
The dealer is in order to solve above-mentioned problem, some design manufacturer promptly directly lays on the host circuit board of electronic equipment and adds extra Data Update hardware circuit and element, so that the user can be just in case when suffering problem, can directly carry out the renewal of system data storage or remedy by this Data Update hardware circuit and element.But this practice can cause cost and the complicacy that need set up the additional hardware circuit on the host circuit board again.
Summary of the invention
Therefore, the present invention's fundamental purpose promptly provides a kind of control device of renewal micro controller device data, so that the operator can reach the purpose of data in the system data storage that upgrades in the micro controller device by the assistance of easy grafting or attended operation and cooperation Software tool.
Another object of the present invention provides a kind of interface arrangement of system data storage of renewal micro controller device, and it can be connected between the data transmission port and a remote computer device of a micro controller device with the kenel of an interface module.By being connected of this interface module and target device, can carry out the data in the system data storage in the target micro controller device.
The present invention is to be provided with a data transmission loop and an address and command transfer loop in an interface module by the technological means that the problem that solves known techniques is adopted; One data source receiving port is connected in this interface module, in order to receive the more new data that this renewal data source is provided; One upgrades data-out port, is connected in this interface module.Be connected in this data source receiving port via this data transmission loop and address and command transfer loop, the more new data that this data source receiving port received is via this data transmission loop and upgrade data-out port and be sent to system data storage in this micro controller device.
In the present invention's the preferred embodiment, the system data storage in this micro controller device is one to be connected in the flash type internal memory of the micro controller of this micro controller device.
Compared to prior art, the present invention has effectively overcome the ROM-BIOS of conventional computer system just in case when the improper operation of user, data damage take place, and the ease of Use by the present invention is the data and the functipnal capability of update calculation machine soon.When carrying out the present invention's Data Update operation, the operator can be easily sees through another remote computer device and the assistance by general tool software, can be sent in the system data storage of micro controller device via interface module upgrading data source, and reach the purpose that system data storage upgrades.Moreover, owing to use the present invention's technology, can on the host circuit board of micro controller device, need not dispose the hardware controls circuit of any Data Update, so can reduce hardware circuit complicated layout and cost on this host circuit board widely.And after the renewal operation of finishing the present invention, the present invention's interface module can be pulled out separation, make the data transmission port of micro controller device recover default work functions.
