Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
To facilitate understanding of the embodiments by those skilled in the art, some terms are explained:
present signal: the presence signal is adapted.
As shown in fig. 1, an embodiment of the present invention provides a high-speed interface parameter configuration system, including: the system comprises a main control board and a plurality of service boards;
the service boards are of various types and used for supporting different service requirements, the chips used by the service boards of different types are different, and the tolerance of each chip to the high-speed channel parameters is different.
In an actual application scenario, the main control board and the service boards are inserted into the backplane, and are interconnected and communicated through the backplane, distances between the service boards in different slots and the main control board are different, and for high-speed signals, different wiring distances mean that high-speed channel parameters such as insertion loss, crosstalk, return loss and the like are different.
In order to improve the communication quality of high-speed signals, parameters for signal optimization, such as equalization, pre-emphasis, de-emphasis, etc., are generally configured at the transmitting end and the receiving end for a high-speed channel. Therefore, in order to ensure that the high-speed interfaces in various combinations work in an optimal state, specific parameters need to be established for each high-speed interface combination situation.
In the embodiment of the present invention, for example, each main control board and each service board have 2 channels: the high-speed channel cannot normally communicate before the parameters are configured, and the low-speed channel is used for the master control board to manage and control the service board. Each service board has a unique slot ID at the backplane that matches it, identified by a pull-up or pull-down, the pull-up representing 1 and the pull-down representing 0, for example: the ID of the first slot is set to 001, the ID of the second slot to 010, and so on. When the main control board controls the service board through the low-speed channel, the service board address is used as a distinction, and when the service board is inserted into the corresponding slot position, the only service board address of the service board is generated according to the slot position ID and the agreed rule.
Specifically, the method comprises the following steps: when the service board is inserted into the first slot, the slot ID where the service board is located is identified, and then a unique service board address D1 is generated according to the agreed rule "base address F0+ slot ID", and the master control board accesses the service board of the slot through D1.
And so on, when the service board is inserted into the fourth slot, its address is F4.
As shown in fig. 2, an embodiment of the present invention provides a method for configuring parameters of a high-speed interface, which is applied to the above system, and includes:
step S1: the main control board obtains a parameter configuration table;
specifically, the first step is to start the main control board, and then the main control board determines whether the service board is inserted into the backplane, including:
the main control board confirms whether the service board is inserted into the back board or not according to the Present signal;
if the Present signal is high level, the service board is inserted into the back board;
if the Present signal is at a low level, the service board is not inserted into the backplane.
In an actual application scenario, when the service board is inserted into the backplane, the Present signal is pulled high by the service board, and when the service board is not inserted into the backplane, the Present signal is pulled low by the service board.
Further, the acquiring, by the main control board, a parameter configuration table includes:
the main control board confirms whether the fixed parameter configuration table is found;
and if the fixed parameter configuration table is not found, the main control board acquires the parameter configuration table based on a parameter scanning algorithm, and updates the parameter configuration table at intervals of preset time.
Generally, each main control board is fixed with a parameter configuration table, which is stored in an array manner, taking a service board with 4 high-speed interfaces as an example: { master control board type, master control board slot position, service board type, service board slot position, first master control high-speed interface, second master control high-speed interface, third master control high-speed interface, fourth master control high-speed interface, first service high-speed interface, second service high-speed interface, third service high-speed interface, and fourth service high-speed interface }.
In an actual application scenario, after the main control board checks that the service board is inserted into the backplane, the main control board checks whether a complete fixed parameter configuration table exists in the main control board, if so, the next parameter configuration is performed, and if the complete fixed parameter configuration table is not found, an automatic parameter scanning program is triggered to acquire the parameter configuration table.
Further, if the fixed parameter configuration table is not found, after the main control board obtains the parameter configuration table based on a parameter scanning algorithm, the method further includes:
and updating the parameter configuration table every other first preset time.
Specifically, the parameter configuration table is dynamically maintained every first preset time (the first preset time may be preset according to the actual operation condition of the system, for example, 1 hour, 12 hours, 24 hours, or 48 hours, etc.), and the parameter configuration table may be updated in a parameter scanning manner, so as to obtain a high-speed channel with the best quality for transmitting the high-speed signal as far as possible.
In an actual application scenario, after the system executes dynamic parameter scanning based on the parameter scanning algorithm and acquires the latest parameter configuration table, the parameter configuration table may be updated once based on the parameter scanning algorithm at intervals of a first preset time in the operation process of the system, or the parameter configuration table may not be updated in the operation process of the system.
Specifically, after the parameter scanning is executed based on the parameter scanning algorithm and the latest parameter configuration table is obtained, if the parameter scanning is executed based on the parameter scanning algorithm at intervals of a first preset time in the operation process of the system and the parameter configuration table is updated once, the operation time of the system is timed based on a timing device (such as a timer and the like) after the service board is inserted into the backplane, and when the timing time is equal to the first preset time, the system executes dynamic parameter scanning based on the parameter scanning algorithm and updates the currently used parameter configuration table once, and then the timer times the operation time of the system again and repeats the steps.
Further, the main control board obtains a parameter configuration table, and further includes:
and if the fixed parameter configuration table is found, immediately updating the parameter configuration table by the main control board based on a parameter scanning algorithm.
In an actual application scenario, in order to achieve the purpose of obtaining a high-speed channel with the best transmission high-speed signal quality as much as possible, after a fixed parameter configuration table is found, because the parameters of the parameter configuration table may not be in the optimal state currently, dynamic parameter scanning may be performed, the found fixed parameter configuration table is updated immediately, then the optimal updated parameter configuration table is obtained, a high-speed interface is configured based on the updated parameter configuration table, and then the high-speed channel with the best transmission high-speed signal quality is obtained.
Further, the acquiring, by the main control board, a parameter configuration table further includes:
if the fixed parameter configuration table is found, the main control board immediately updates the parameter configuration table based on a parameter scanning algorithm;
and updating the parameter configuration table every second preset time.
In an actual application scenario, after the service board is inserted into the backplane, the operation time of the entire system may be relatively long, and in order to achieve the purpose of obtaining a high-speed channel with the best quality for transmitting high-speed signals as much as possible, therefore, in the operation process of the system, dynamic parameter scanning may be performed based on a parameter scanning algorithm every second preset time (e.g., 1 hour, 2 hours, or 3 hours, etc.), a parameter configuration table currently used by the system is updated, then, an optimal updated parameter configuration table is obtained, a high-speed interface is configured based on the updated parameter configuration table, and then, the high-speed channel with the best quality for transmitting high-speed signals is obtained.
Further, the acquiring, by the main control board, a parameter configuration table further includes:
and if the fixed parameter configuration table is found, updating the parameter configuration table at intervals of second preset time.
In an actual application scene, after a fixed parameter configuration table is found, a high-speed interface is directly configured on the basis of the existing fixed parameter configuration table; and then in the running process of the system, executing dynamic parameter scanning once at intervals of a second preset time based on a parameter scanning algorithm, updating a parameter configuration table currently used by the system, then obtaining an optimal updated parameter configuration table, configuring a high-speed interface based on the updated parameter configuration table, and then obtaining a high-speed channel with optimal transmission high-speed signal quality.
Specifically, after the service board is inserted into the backplane, the running time of the system is timed based on a timing device (e.g., a timer, etc.), when the timed time is equal to a second preset time, the system updates the currently used parameter configuration table once based on a parameter scanning algorithm, and then the timer times the running time of the system again, and repeats the above steps.
It should be noted that, in the embodiments of the present invention, the first preset time and the second preset time are not substantially different and are used to represent time.
Further, obtaining the fixed parameter configuration table includes:
traversing all types of the main control boards, slot positions of the main control boards and the high-speed interfaces of the main control boards to obtain a first result; the first result comprises all the types of the main control boards, the slot positions of the main control boards, the high-speed interfaces of the main control boards and other information;
traversing all types of the service boards, service board slot positions and the high-speed interfaces of the service boards to obtain a second result; the second result comprises information such as the type of the service board, the slot position of the service board, the high-speed interface of the service board and the like;
determining a plurality of high speed lanes based on the first and second results; after the high-speed interface of a main control board and the high-speed interface of a service board complete parameter configuration, a high-speed channel which can be used for transmitting high-speed signals is formed; because each main control board may have a plurality of high-speed interfaces, and each service board may also have a plurality of high-speed interfaces, a plurality of high-speed channels may be formed;
determining a first set of target parameters for each of the high speed lanes;
determining the parameter configuration table based on a plurality of the first target parameter groups.
In an actual application scene, the types, the slot positions and the ports of all the main control boards and the types, the slot positions and the ports of the service boards are traversed, and a unique group of optimal parameters are tested in advance.
For example: 2 main control board slots, 2 service board slots, 1 type main control board and 1 type service board are arranged on the backboard, and each main control board and each service board are provided with 8 high-speed interfaces which are in one-to-one correspondence, so that 2 x 8 is 32 groups of parameters; and testing 32 groups of parameters in advance, determining an optimal group of parameters corresponding to each high-speed channel, and writing each high-speed channel and the optimal group of parameters corresponding to the high-speed channel into a parameter configuration table so as to directly perform parameter calling and parameter distribution on a subsequent main control board.
Further, the acquiring, by the main control board, the parameter configuration table based on a parameter scanning algorithm includes:
the main control board obtains a plurality of groups of parameters; each group of parameters comprises main control board parameters and service board parameters;
acquiring a second target parameter group of each high-speed channel based on the multiple groups of parameters;
determining the parameter configuration table based on a plurality of the second target parameter groups.
The embodiment of the invention determines the parameter configuration table based on the dynamic parameter scanning method, can be automatically realized by a program, does not need manual intervention or actual measurement in advance, can dynamically refresh the parameter configuration table, and ensures that each group of parameters is a real-time optimal solution.
Further, the acquiring the target parameter set of each high speed channel includes:
the main control board sends the plurality of groups of parameters to the service board based on a low-speed interface;
the main control board configures the high-speed interface of the main control board based on the main control board parameters of each group of parameters; meanwhile, the service board configures the high-speed interface of the service board based on the service board parameters of each group of the parameters; forming a high-speed channel;
comparing the error rate of the high-speed channel matched with each group of the parameters;
and determining a group of parameters corresponding to the minimum bit error rate as a second target parameter group of the high-speed channel.
In an actual application scene, a main control board obtains multiple groups of parameters in a parameter scanning mode, the main control board transmits each group of parameters to a service board through a low-speed interface, the service board and the main control board configure high-speed interfaces according to the respective distributed parameters, then package sending tests are carried out, the error rate of the service board and the main control board is counted and recorded, finally, the error rates under all parameter combinations are compared, a group of parameters corresponding to the minimum value is taken as the optimal parameters of the high-speed channel, and the high-speed channel and a matched group of parameters are written into a parameter configuration table.
For example: determining each group of parameters based on a stepping method, wherein the parameters required to be configured by the high-speed interface of the main control board are A1 and A2, the parameters required to be configured by the high-speed interface of the service board are B1 and B2, and t is a minimum stepping value:
ensuring A2min B1min B2min to be constant, and increasing A1 from min to max according to a step value t:
{A1min，A2min，B1min，B2min}、{A1min+t，A2min，B1min，B2min}、{A1min+2t，A2min，B1min，B2min}…{A1max，A2min，B1min，B2min}
ensuring A2min + t unchanged, scanning the a1 parameter according to the above steps, then ensuring A2min +2t unchanged, scanning the a1 parameter, and so on, scanning the A2 parameter to A2 max:
{A1min，A2min+t，B1min，B2min}、{A1min+t，A2min+t，B1min，B2min}、{A1min+2t，A2min+t，B1min，B2min}…{A1max，A2min+t，B1min，B2min}
{A1min，A2min+2t，B1min，B2min}、{A1min+t，A2min+2t，B1min，B2min}、{A1min+2t，A2min+2t，B1min，B2min}…{A1max，A2min+2t，B1min，B2min}
{A1min，A2max，B1min，B2min}、{A1min+t，A2max，B1min，B2min}、{A1min+2t，A2max，B1min，B2min}…{A1max，A2max，B1min，B2min}
