The system chip is a central processing unit 71, and a platform path controller electrically connected to the central processing unit. 72. Each management module 8 monitors the operation status of several peripheral elements 1, and when a failure event occurs in the peripheral element 1, the corresponding management module 8 triggers a system management interrupt, and transmits it through the platform path controller 72. The corresponding signal is sent to the central processing unit 71, and then the central processing unit 71 provides the corresponding service type

However, in the existing architecture design, when a failure event occurs in each peripheral element 1, the corresponding management module 8 must trigger the system management interrupt via an independent physical circuit, such as a system management interrupt (SMI: System Management Interrupt) circuit 9. That is to say, the number of physical lines electrically connected to each management module 8 and the platform path controller 72 of the system chip 7 must be the same as the number of peripheral components 1 electrically connected to the management module 8, and according to the management module 8 also needs to trigger the system management interrupt according to its own needs. The number of interrupt types and the platform path controller 72 of the system chip 7 are electrically connected to the same number of physical lines. For example, when the number of management modules 8 is M, each management module 8. The number of peripheral elements 1 that are electrically connected is N, and the number of interrupt types that each management module 8 itself needs to trigger a system management interrupt is P, then the number of physical lines of all management modules electrically connected to the platform path controller 72 There will be as many as M×(N+P), because each physical line will occupy at least one pin of the management module, so that the space for other components or lines in the servo system will be limited. In addition, the number of pins that the management module 8 can configure for other functions is also limited, so there is a need for improvement.

Therefore, the object of the present invention is to provide a servo system which can improve the shortcomings of the prior art.

Therefore, the servo system of the present invention is electrically connected to a peripheral element, and the servo system includes a system module, a management module, and a transmission interface.

The system module executes a basic input output system program, and the basic input output system program records a comparison table related to a plurality of service types corresponding to a plurality of interrupt codes respectively, and the interrupt codes respectively correspond to a plurality of interrupt events.

The management module is electrically connected to the peripheral element.

The transmission interface is correspondingly electrically connected between the management module and the system module.

When the management module detects an interrupt event, the management module generates an interrupt trigger signal and a corresponding interrupt code according to the interrupt event, and transmits the interrupt trigger signal to the system module through the corresponding transmission interface .

The system module sends an inquiry signal to the management module according to the received interrupt trigger signal.

The management module transmits the interrupt code corresponding to the interrupt event to the system module.

The system module searches and executes the corresponding service type from the comparison table according to the received interrupt code.

The effect of the present invention is: when the management module detects the interruption trigger signal, the system module switches to the system interruption mode and sends an inquiry signal to the management module through the transmission interface in a polling manner, and According to the error code returned by the management module that detected the interruption event, the corresponding service type is searched, thereby greatly reducing the physical lines configured by the system module to detect abnormal operation events.

The main purpose of this proposal is to reduce the physical circuit of the system management interrupt (SMI: System Management Interrupt, hereinafter referred to as SMI) of the servo system. When the sub-controller in the servo system triggers the system management interrupt due to different requirements , Triggered by the same group of physical lines that manage interruptions within the servo system, and then the servo system asks the sub-controller for the service type required by the communication interface, and triggers the purpose of different service types through the same group of physical lines, thereby reducing the number of servo The system manages interrupted physical lines.

When one of the management modules 3 detects an interruption event of an electrically connected peripheral element 1, the management module 3 is triggered to generate an interruption trigger signal and an interruption code corresponding to the interruption event according to the interruption event, and The interrupt trigger signal is transmitted to the system module 2 through the corresponding transmission interface 4. Specifically, the management module 3 transmits the interrupt trigger signal to the platform path controller 22 through the first bus 41. The interrupt trigger signal is sent to the central processing unit 21 through the platform path controller 22 .

When the system module 2 receives the interrupt trigger signal sent by one of the management modules 3 (that is, the central processing unit 21 receives the interrupt trigger signal), it executes the BIOS program to enter a Corresponding system interrupt management mode (SMM: system management mode), the system module 2 in the corresponding system interrupt management mode, according to the interrupt trigger signal corresponding to send out an inquiry signal, and through the transmission interface 4 corresponding After the received interrupt trigger signal, the inquiry signal is sent to the management modules 3 corresponding to the received interrupt trigger signal.

Since each management module 3 and the system module 2 are electrically connected with only two physical lines, in the other In one embodiment, when each management module 3 is designed to trigger and generate an interruption trigger signal corresponding to 100 different service requirements, the physical line electrically connected between each management module 3 and the system module 2 is still Only two sets of busbars, such as the aforementioned first and second busbars 41, 42, are not related to the number of peripheral components electrically connected to each management module 3, and also to the service requirements of each management module 3. The number of types of interrupt trigger signals generated by the trigger is irrelevant, so the number of physical lines between system module 2 and all management modules 3 will only change according to the number of management modules designed to issue interrupt trigger signals, such as by The number of management modules designed to send out interrupt trigger signals is M, then the number of physical lines related to system management interruption between these management modules and the system module is 2×M, which is far Less than that in the prior art, each management module needs to design a physical line related to system management interruption for each different service type, that is to say, when there are M management modules in the prior art, each of which has the requirements of N service types , then the prior art needs to design N×M physical circuits on the system module for executing the system management interruption mechanism, so the implementation of the technology in this case will greatly reduce the amount of time between the system module 2 and all management modules 3 for executing system management. The number of physical lines configured is interrupted, that is to say, this embodiment can simplify the design, reduce the settings for the lines related to the servo system, improve the compatibility between platforms, thereby shorten the development time and reduce the cost. achieve the creative purpose of the present invention.
