Therefore, based on the transaction record information stored in the block chain, the core enterprise can effectively inquire the distribution condition of the accounts provided by the core enterprise among the account holding users.
Based on the application scenario architecture, one or more embodiments of the present specification provide a transaction query method based on a blockchain, fig. 2 is a flowchart of the transaction query method based on the blockchain provided by one or more embodiments of the present specification, and the method in fig. 2 can be executed by a first blockchain node in fig. 1, as shown in fig. 2, and the method includes the following steps:
step S102, receiving a transaction query request sent by a terminal device of a core enterprise user, wherein the transaction query request comprises the time to be queried and the identification of the transaction voucher data to be queried;
step S104, acquiring corresponding target transaction record information with the transaction time within the time to be inquired from the block chain according to the identification of the transaction voucher data;
step S106, calling a first intelligent contract, and generating a distribution diagram of accounts corresponding to the transaction voucher data to be inquired in the time to be inquired according to the target transaction record information, wherein the distribution diagram represents the distribution condition of the accounts among account holding users in the time to be inquired;
and step S108, sending the distribution map to the terminal equipment of the core enterprise user so as to enable the terminal equipment of the core enterprise user to display the distribution map.
In one or more embodiments of the present specification, based on transaction record information stored in a blockchain, a core enterprise effectively queries a distribution status of accounts provided by the core enterprise among account holding users; and moreover, by generating the distribution map of the accounts corresponding to the transaction voucher data to be inquired, the core enterprise user can clearly and clearly check the distribution condition of the accounts provided by the core enterprise user within the time to be inquired, the core enterprise user does not need to manually card the distribution condition of the accounts according to the transaction record information, and the inquiry efficiency and the user experience are improved.
In order to avoid losing or tampering transaction data of transactions performed based on accounts provided by a core enterprise between provider users and other organizations (such as banks), in one or more embodiments of the present specification, when a second blockchain node receives a transaction request sent by a terminal device of a provider user, a corresponding transaction operation is performed according to the transaction request, transaction record information is generated according to transaction time, an identifier of transaction credential data included in the transaction request, and the like, and the transaction record information is written into a blockchain, so as to provide an effective data basis for query of transactions; the specific generation process of the transaction record information is detailed later, and the second block link point and the first block link point may be the same block link point or different block link points. Based on this, as shown in fig. 3, step S104 includes:
step S104-2, matching the identification of the transaction voucher data to be inquired with the identification of the transaction voucher data contained in the transaction record information stored in the blockchain, and matching the time to be inquired with the transaction time contained in the transaction record information stored in the blockchain;
and step S104-4, if the matching is successful, the corresponding transaction record information is used as the target transaction record information.
Specifically, the identifier of the transaction voucher data to be inquired is matched with the identifier of the transaction voucher data contained in the transaction record information stored in the blockchain, and if the matching fails, the transaction record information where the identifier of the transaction voucher data which fails to be matched is determined not to be the transaction record information of the account corresponding to the transaction voucher data to be inquired; if the matching is successful, determining that the transaction record information of the identifier of the successfully matched transaction voucher data is the transaction record information of the account corresponding to the transaction voucher data to be inquired, reading the transaction time from the transaction record information of the identifier of the successfully matched transaction voucher data, matching the read transaction time with the time to be inquired, and if the matching is successful, taking the transaction record information of the successfully matched transaction time as the target transaction record information. It should be noted that if the target transaction record information is not obtained, the prompt information is sent to the terminal device of the core enterprise user.
Further, in this embodiment of the present specification, the time to be queried may be a certain time (e.g., 0 minute and 0 second at 12 hours at 8 month and 15 days in 2019), or may be a certain time period (e.g., from 8 month and 1 day in 2019 to 8 month and 15 days in 2019), and the core enterprise user may operate the terminal device to set the time. When the time to be queried is a certain moment, correspondingly, matching the read transaction time with the time to be queried comprises the following steps: determining whether the read transaction time is before the time to be inquired, if so, matching is successful, otherwise, matching is failed; for example, the transaction time read is 2 minutes 15 seconds at 3 hours at 8 months and 15 days in 2019, and the matching is determined to be successful before 0 minutes 0 seconds at 12 hours at 8 months and 15 days in 2019. When the time to be queried is a certain period, correspondingly, matching the read transaction time with the time to be queried comprises the following steps: determining whether the read transaction time is within the time to be inquired, if so, matching is successful, otherwise, matching is failed; for example, the transaction time read is 2019, 8, month 10, which is within 2019, 8 month 1, to 2019, 8 month 15, determining that the match was successful.
Considering that the time to be queried set by the core enterprise user may be a time period with a small span, or only a certain time, or may also be a time period with a large span, in order to improve readability and aesthetic property of a distribution graph to be generated, in one or more embodiments of the present specification, a time division rule is set in advance to divide the time to be queried into at least one time period, so as to count status information of accounts held by each account holding user in each time period, and generate the distribution graph, so as to avoid a problem that the time period with a large span is difficult to display in one distribution graph; it should be noted that, when the time to be queried is a certain time, the divided time period is the time. Specifically, as shown in fig. 4, step S106 includes:
step S106-2, calling a first intelligent contract, and dividing the time to be inquired into at least one time period according to a preset time division rule;
the time division rule can be set in practical application according to needs, for example, when the time to be queried is less than 5 days, the time division can be performed by taking 12 hours as a division unit, namely, the time division is performed by taking 12 hours as a time period; when the time to be queried is between 5 and 30 days, time division can be performed by taking 24 hours as a division unit, namely each time period is 1 day; when the time to be queried is 30 days to 50 days, time division may be performed in units of division of 48 hours, that is, each time period is 2 days.
Step S106-4, acquiring transaction time, the amount of the transaction account, user information of a transfer-out user of the transaction account and user information of a transfer-in user from the target transaction record information;
step S106-6, taking the roll-out user and the roll-in user as account holding users, and determining the state information of accounts held by each account holding user in each time period according to the acquired transaction time, the amount of the transaction accounts, the user information of the roll-out user of the transaction accounts and the user information of the roll-in user;
specifically, a roll-out user and a roll-in user of a transaction account are used as account holding users, user information of the roll-out user and user information of the roll-in user of the transaction account are used as user information of each account holding user, and each account holding user is distinguished, wherein the user information comprises a user name, a user contact way and the like; determining target transaction record information corresponding to each time period according to the transaction time in the target transaction record information; and according to the target transaction record information corresponding to each time period, counting the amount of the accounts held by each account holding user in each time period, and the information such as the proportion of the amount of the accounts held by each account holding user in each time period in the total amount of the accounts provided by the core enterprise.
For example, the target transaction record information includes, for each time period of 1 day, time division in a division unit of 24 hours:
transaction time: 8, month 8, 1, day 6 in 2019, user information of the account transfer user: core enterprises and the like, account transfer into user information of users: supplier a, etc., amount of transaction account: 100 ten thousand yuan;

Note that the form of the state information of the account held by each account holding user in each time period counted based on the target transaction record information is not limited to the above form, and may be set by itself as necessary in practical applications, for example, a separate table is created for each account holding user.
S106-8, selecting different filling styles for representing each account holding user from preset filling styles;
the filling pattern can be set in practical application according to needs, such as color filling, pattern filling, and the like.
And S106-10, generating a distribution diagram in which accounts corresponding to the transaction voucher data are distributed among all account holding users within the time to be inquired according to the time sequence and the selected filling style and the determined state information.
A distribution diagram generated according to the selected filling pattern and the determined state information is shown in fig. 5, the distribution diagram includes a main body part and an annotation part, the main body part shows the distribution condition of accounts among the holding users, and the annotation part includes the association information of the user information (such as user name) of each account holding user and the filling pattern; further, as can be seen from the distribution diagram shown in fig. 5: in the time period from 8 month 1 in 2019 to 8 month 3 in 2019, 100 ten thousand accounts are distributed at the account holding user supplier A; in the time period of 2019, 8 and 4 days in 8 and 5 days in 2019, 100 ten thousand accounts are distributed in the account holding user supplier B; from 6 days at time period 8 month to 10 days at time period 8 month, 20 ten thousand of accounts are distributed at the account holding user supplier b, 60 ten thousand of accounts are distributed at the account holding user supplier c, and 20 ten thousand of accounts are distributed at the account holding user supplier d; in the time period from 11 days 8 month in 2019 to 13 days 8 month in 2019, 20 ten thousand accounts are distributed at the supplier b of the account holding user, 60 ten thousand accounts are distributed at the supplier c of the account holding user, 15 ten thousand accounts are distributed at the supplier d of the account holding user, and 5 ten thousand accounts are distributed at the bank 1 of the account holding user; in the time period 2019, day 8 and 14, and in the time period 2019, day 8 and 15, 20 ten thousand of accounts are distributed at the account holding user supplier b, 45 ten thousand of accounts are distributed at the account holding user supplier e, 10 ten thousand of accounts are distributed at the account holding user supplier e, and 25 ten thousand of accounts are distributed at the account holding user bank 1.
Therefore, the core enterprise user can effectively inquire the distribution condition of the corresponding accounts among the account holding users only by providing the to-be-inquired time and the identification of the to-be-inquired transaction voucher data, and the distribution condition of the accounts provided by the core enterprise user in each time period can be seen clearly from the distribution diagram without the operations of integrating transaction record information and the like of the core enterprise user.
Considering that most users have a habit of using a mouse, that is, the position of the cursor of the mouse is the current focus position of the user, based on this, in order to make the core enterprise user have a better query experience, in one or more embodiments of the present specification, the method further includes:
step A2, if the cursor is detected to be located in the main body part of the distribution diagram, acquiring the position information of the cursor; or if the triggering operation of the core enterprise user on the main body part of the distribution graph is detected, acquiring the position information of the operated position;
step a4, determining a target time period closest to the acquired position information;
specifically, a first distance between the acquired position information and an adjacent previous time period is measured, a second distance between the acquired position information and an adjacent subsequent time period is measured, the first distance and the second distance are compared, and a time period corresponding to the small distance is used as a target time period.
Step A6, determining the distribution information of the accounts among the account holding users in the target time period;
specifically, from the state information of the accounts held by the account holding user in each time period of the statistics, the state information of the accounts held by the account holding user in the target time period is acquired, and according to the acquired state information, distribution information of the accounts among the account holding users in the target time period is generated; the specific content of the distribution information may be set as needed in practical application, for example, the distribution information includes time information, a user name of each account holding user holding the account, an amount of the account held by each account holding user holding the account, and the like.
And step A8, displaying the determined distribution information.
Fig. 6 shows a schematic diagram of distribution information.
By detecting the position of a mouse cursor or detecting the triggering operation of the core enterprise user on the main body part of the distribution graph and displaying the distribution information of the corresponding accounts, the core enterprise user can know the distribution condition of the accounts among the users in each account more clearly in a certain time period, and the human-computer interaction experience and the query experience of the core enterprise user are improved.
Furthermore, the distribution diagram not only can reflect the distribution condition of the accounts among the account holding users, but also can reflect the change state of the accounts at a certain account holding user, namely, the change of the area corresponding to each filling mode over time reflects the change of the accounts at a certain account holding user over time. However, when there are many account holding users, especially when different colors are used to represent different account holding users, a phenomenon that is difficult to distinguish by naked eyes may exist at the boundary of different filling patterns in the distribution diagram, so that it becomes difficult for a core enterprise user to refer to a change of accounts at a certain account holding user. Based on this, this description in one or more embodiments, also includes:
step B2, if the associated information included by the cursor located in the annotation part is detected, the filling style corresponding to the associated information of the cursor is differentially displayed in the main body part of the distribution diagram; alternatively, the first and second electrodes may be,
step B4, if the triggering operation of the core enterprise user on the associated information is detected, the filling style corresponding to the operated associated information is shown in the distribution diagram.
The different display mode can be emphasis display, such as color deepening, thickening of filling pattern lines, thickening of filling area frames and the like; other filling patterns can be blurred on the basis of the emphasized display, and the like, and can be set automatically according to needs in practical application. As an example, as shown in fig. 7, when the first tile link point detects that the cursor is located in the associated information corresponding to the provider c, the frame corresponding to the filled area is displayed in bold. Therefore, by displaying the filling style corresponding to the associated information where the cursor is or displaying the filling style corresponding to the operated associated information in a distinguished manner, not only can the change condition of the account at a certain account holding user be displayed to the core enterprise user more intuitively, but also for the core enterprise user, the human-computer interaction experience is improved.
It should be noted that the distribution diagrams shown in fig. 5 to 7 are only for illustration and not for limitation, and the patterns of the distribution diagrams can be designed according to the needs in practical applications.
In one or more embodiments of the present specification, based on transaction record information stored in a blockchain, a core enterprise can effectively query distribution conditions of accounts provided by the core enterprise among account holding users; meanwhile, the circulation path diagram of the accounts corresponding to the transaction certificate data to be inquired is generated, and the generated circulation path diagram is sent to the terminal equipment of the core enterprise user, so that the core enterprise user can clearly and clearly check all circulation information of the accounts corresponding to the transaction certificate data to be inquired, the core enterprise user does not need to manually comb the circulation information of the accounts according to each transaction record information, and the inquiry efficiency and the user experience are improved.
Corresponding to the above transaction query method based on the blockchain, one or more embodiments of the present specification further provide a transaction data processing method based on the blockchain; fig. 8 is a schematic application scenario diagram of a transaction data processing method based on a blockchain according to one or more embodiments of the present specification, as shown in fig. 8, the application scenario includes: a second blockchain node, terminal equipment of a core enterprise user and terminal equipment of a provider user; the second block chain node is a node in the block chain, and the second block chain link point and the first block chain link point can be the same block chain link point or different block chain nodes; the terminal equipment of the core enterprise user and the terminal equipment of the supplier user can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like, and the terminal equipment of the core enterprise user and the terminal equipment of the supplier user are in communication connection with the first block link point through a wireless network.
Specifically, the terminal device of the core enterprise user receives the accounts payable data sent by the core enterprise user and sends the accounts payable data to the second blockchain node; the accounts payable data comprises account amount, user information (such as name, enterprise name of the enterprise, contact information and the like) of the supplier user, account information (such as agricultural bank) of the account opening bank of the supplier user, account information (such as card number of a bank card) of the account opening bank of the supplier user, payment mode and the like;
the second block chain node receives the accounts payable data sent by the terminal equipment of the core enterprise user, and sends the accounts payable data to the terminal equipment of the provider user according to the user information of the provider user included in the accounts payable data, so that the provider user can check the accounts payable data; when the audit passing information sent by the terminal equipment of the supplier user is received, generating transaction voucher data according to the accounts payable data; when a transaction request based on the transaction voucher data sent by the terminal equipment of the supplier user is received, executing corresponding transaction operation according to the transaction request, generating transaction record information, and writing the transaction record information into the block chain;
the terminal equipment of the supplier user receives the accounts payable data sent by the second block chain node, displays the accounts payable data so as to enable the supplier user to carry out auditing, and sends the auditing passing information to the second block chain node when receiving the auditing passing information sent by the supplier user so as to enable the second block chain node to generate transaction voucher data according to the accounts payable data; and when transaction data based on the transaction voucher data sent by the supplier user is received, generating a transaction request according to the transaction data, and sending the transaction request to the second blockchain node. After receiving the account corresponding to the transaction voucher data provided by the core enterprise user, the provider user can use the account to perform transactions with other provider users, banks and the like, such as transfer-out, transfer-in, financing and the like of the account; correspondingly, the transaction data includes the amount of the transaction account, the user information and the bank account information of the transfer-out user of the transaction account, the user information and the bank account information of the transfer-in user of the transaction account, and the like.
In the application scenario, transaction data processing is performed in a trusted environment of the block chain, so that the transaction process is transparent and visible in multiple ways, and the authenticity and the validity of the transaction are ensured; and by writing the transaction record information into the block chain, the non-tampering property and the open-check property of the uplink data are ensured, the problems of data loss, data counterfeiting and the like are effectively avoided, and an effective data base is provided for the inquiry of the transaction.
Based on the application scenario architecture, one or more embodiments of the present specification further provide a transaction data processing method based on a block chain; fig. 9 is a flowchart illustrating a method for processing transaction data based on a blockchain according to one or more embodiments of the present disclosure, where the method in fig. 9 can be performed by a second blockchain link point in fig. 8, as shown in fig. 9, and the method includes the following steps:
step S202, receiving accounts payable data sent by terminal equipment of a core enterprise user;
step S204, generating transaction voucher data according to the accounts payable data and generating an identifier of the transaction voucher data;
step S206, the identification of the transaction voucher data is sent to the terminal equipment of the core enterprise user, so that the core enterprise user can inquire the distribution condition of the accounts corresponding to the transaction voucher data according to the identification of the transaction voucher data;
step S208, when a transaction request sent by the terminal equipment of the supplier user is received, executing corresponding transaction operation according to the transaction request, and generating transaction record information according to the transaction time and the identification of the transaction voucher data;
step S210, writing the transaction record information into the block chain.
In one or more embodiments of the present description, by conducting transactions in a trusted environment of a blockchain, the transaction process is transparent and visible in many ways, thus ensuring the authenticity and validity of the transaction; and by writing the transaction record information into the block chain, the non-tampering property and the open-check property of the uplink data are ensured, the problems of data loss, data counterfeiting and the like are effectively avoided, and an effective data base is provided for the inquiry of the transaction.
Since the accounts payable data includes the account amount and the related information of the supplier, in order to ensure the accuracy of the transaction credential data generated based on the accounts payable data, in one or more embodiments of the present specification, the step S204 of generating the transaction credential data according to the accounts payable data includes:
step S204-2, sending the accounts payable data to the corresponding terminal equipment of the supplier user according to the user information of the supplier user included in the accounts payable data, so that the supplier user can check the accounts payable data;
and step S204-4, if the audit passing information sent by the terminal equipment of the supplier user is received within the preset time, generating transaction voucher data according to the accounts payable data.
Specifically, the second block link point sends the received accounts payable data to the terminal device of the provider user according to a contact way included in the user information of the provider user, judges whether audit passing information sent by the terminal device of the provider user is received within a preset time length, and generates transaction voucher data according to the accounts payable data when the judgment result is yes; if not, sending transaction failure information to the terminal equipment of the core enterprise user; the contact information includes, for example, mailbox information, account information of the supplier user on the financial platform of the supply chain, and the like. Therefore, by sending the accounts payable data to the supplier user for auditing, the risk that the transaction voucher data is wrong due to the fact that the information included in the accounts payable data is wrong, and disputes are caused due to the fact that the transaction voucher data is wrong is reduced.
In order to avoid the illegal transaction after some supplier users receive the account provided by the core enterprise user, in one or more embodiments of the present specification, as shown in fig. 10, the step S208 of executing a corresponding transaction operation according to the transaction request includes:
calling a second intelligent contract, and determining whether the transaction data included in the transaction request meets the transaction rule of the transaction certificate data based on the second intelligent contract; and if the transaction data meets the transaction rule of the transaction certificate data, executing corresponding transaction operation according to the transaction data.
The transaction data includes, but is not limited to, the amount of the transaction account, user information and bank account information of the transfer-out user of the transaction account, user information and bank account information of the transfer-in user of the transaction account. As an example, when the transaction request is used to request an account transfer (e.g., transfer out) operation, the account to be transferred is transferred out from the bank account corresponding to the bank account information of the transfer-out user according to the amount of the account to be transferred included in the transaction data, and is transferred into the bank account corresponding to the bank account information of the transfer-in user.
Further, if the transaction data does not meet the transaction rules of the transaction voucher data, transaction failure information is sent to the terminal equipment of the supplier user.
Therefore, whether the transaction data included in the transaction request meets the transaction rule of the transaction certificate data or not is automatically determined based on the second intelligent contract in the block chain, the phenomena that a supplier user uses accounts provided by a core enterprise user to conduct illegal transactions and the like are effectively avoided, and the stable development of supply chain finance is promoted.
Furthermore, in order to clarify the transaction items between the core enterprise and the supplier, such as the amount of the account and the transaction rules, the core enterprise and the supplier will generally make a transaction contract; in order to ensure that the transaction rules satisfied by the transaction data determined based on the intelligent contract are consistent with the contract-agreed transaction rules, in one or more embodiments of the present specification, as shown in fig. 10, before step S208, the method further includes:

It should be noted that the electronic contract may be signed by the core enterprise user and the provider user, and may also be signed by other users specified by the core enterprise and other users specified by the provider; it is further noted that the core enterprise user may upload the electronic contract before submitting the accounts payable data, may upload the electronic contract after submitting the accounts payable data, and may submit the accounts payable data and upload the electronic contract simultaneously; that is, step S207-2 may be executed before step S202, may be executed after step S202, and may be executed simultaneously with step S202.
Step S207-4, acquiring a transaction rule of the transaction certificate data in the electronic contract, and deploying a second intelligent contract in the block chain according to the acquired transaction rule;
specifically, the first blockchain node searches for a preset key field in the electronic contract, and uses a term including the key field as a transaction rule of the transaction certificate data. The key field can be set in practical application according to needs, for example, the key field includes a financing ratio, and a term "the financing ratio is not greater than 50% of the amount of the account" included in the financing ratio field in the electronic contract is used as a transaction rule of the transaction voucher data.
By acquiring the transaction rule from the electronic contract sent by the terminal equipment of the core enterprise user and deploying the second intelligent contract in the blockchain according to the acquired transaction rule, the consistency of the intelligent contract and contract agreement is ensured, the transaction rule does not need to be manually edited by the user, the user operation is reduced, and the user experience is improved.
The second intelligent contracts, which are deployed by the first block link points according to different transaction rules, are different because the transaction rules agreed between different core enterprises and different suppliers are different; in order to effectively distinguish the second intelligent contracts and effectively identify the second intelligent contracts corresponding to different transaction credential data, in one or more embodiments of the present specification, after step S207-4, the method further includes:
step D2, generating a contract identifier of the second intelligent contract;
and D4, performing association recording on the generated transaction voucher data identifier and the contract identifier to obtain association recording information.
And performing association recording on the generated identification of the transaction voucher data and the contract identification, so that when a transaction request based on the transaction voucher data is received, a second intelligent contract needing to be invoked is determined according to the identification of the transaction voucher data included in the transaction request and the obtained association recording information. That is, in one or more embodiments of the present specification, the invoking the second smart contract includes:
step E2, acquiring a corresponding contract identifier in the associated record information according to the identifier of the transaction voucher data included in the transaction request;
and E4, calling the second intelligent contract corresponding to the acquired contract identification.
Therefore, accurate calling of the second intelligent contract is achieved based on the obtained associated record information.
Further, in order to provide sufficiently effective information for the core enterprise user to inquire the distribution condition of the provided accounts among the account holding users, in one or more embodiments of the present specification, the step S208 of generating transaction record information according to the transaction time and the identification of the transaction credential data includes:
and performing association recording on the identification of the transaction voucher data, the amount of the transaction account included in the transaction request, the user information of the transfer-out supplier user of the transaction account and the user information of the transfer-in supplier user, and taking the recorded information as transaction record information.
Further, in order to avoid that the accounts payable data is maliciously tampered and inconsistent with the transaction credential data, in one or more embodiments of the present specification, after the generating the identifier of the transaction credential data in step S204, the method further includes:
and associating the accounts payable data, the transaction voucher data and the identification of the transaction voucher data with a record, and writing the recorded information into the block chain.
In a specific embodiment, taking the example that the second block link point receives the accounts payable data and the electronic contract sent by the terminal device of the core enterprise user at the same time, as shown in fig. 11, the method includes:

step S304, the second block link point sends the accounts payable data to the corresponding terminal equipment of the supplier user according to the user information of the supplier user included in the accounts payable data;
step S306, the second block link point judges whether the audit passing information sent by the terminal equipment of the supplier user is received within the preset time, if yes, the step S308 is executed, otherwise, the transaction failure information is sent to the terminal equipment of the core enterprise user;
step S308, the second block link point generates transaction voucher data according to the accounts payable data and generates an identifier of the transaction voucher data;
step S310, the second block link point associates and records the accounts payable data, the transaction voucher data and the identification of the transaction voucher data, writes the recorded information into the block chain, and correspondingly sends the accounts payable data and the identification of the accounts payable data to the terminal equipment of the core enterprise user and the terminal equipment of the supplier user respectively;
step S312, the second block chain node searches for a preset key field in the electronic contract, and takes a term comprising the key field as a transaction rule of the transaction certificate data;
step S314, deploying the intelligent contract in the block chain by the second block chain link point according to the transaction rule, and generating a contract identifier of the intelligent contract;

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In the 30 s of the 20 th century, improvements in a technology could clearly be distinguished between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the units may be implemented in the same software and/or hardware or in multiple software and/or hardware when implementing the embodiments of the present description.

Furthermore, the description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
The description has been presented with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
