Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a communication method, a device and a medium of market data, which are used for applying a large amount of continuous space when applying a cache space so as to store more market data.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for communicating market data according to an embodiment of the present disclosure, and as shown in fig. 1, the method includes:
s10: acquiring market data sent by hardware equipment.
The hardware device in this embodiment refers to a Field Programmable Gate Array (FPGA), which is a product of further development based on Programmable devices such as PAL and GAL. The circuit is used as a semi-custom circuit in the field of application-specific integrated circuits, not only overcomes the defects of the custom circuit, but also overcomes the defect that the number of gate circuits of the original programmable device is limited. The system receives market data uploaded by each region through protocol docking and sends the market data to the driver through protocol docking. The market data of the present application includes, in addition to specific financial data, related transmission instructions, information, and the like.
S11: and applying for a cache space according to the pre-reserved cache address and the sending density of the market data.
It can be understood that, in order to ensure the integrity of the market data and the rapidity of reading, the cache space in the present application is a continuous space, and the cache space is applied when market data communication is required. In the prior art, when a driver applies for a cache space to store market data, a Direct Memory Access (DMA) technology is usually used to apply for the space, and DMA is a hardware mechanism that allows a peripheral device and a main Memory to directly transmit I/O data without involvement of a system processor. However, in the specific implementation of the method, due to the use of the user, there are not enough continuous addresses in the memory, and the user cannot apply for enough cache space, usually only 4MB of space at most. In this embodiment, a cache address is reserved in advance, and an intelligent continuous Memory allocation technique (CMA) is used, so that the cache address is not used for executing other commands in the Memory using process, and is only used as a cache space when market data transmission is required, and the size of the applicable cache space is determined by the size of the reserved cache address, so that the continuous cache space is more easily applied. It can be understood that the size of the cache address reserved in advance may be set according to the size of the market data volume of each region and the actual hardware facilities, for example, the market data volume handed in is large, the density is high, and the hardware memory is large, so there may be more cache addresses reserved. The cache space in this embodiment is applied according to the cache address, and the size of the cache space applied each time can be dynamically adjusted according to the sending density of the market data. For example, if a certain transaction is frequent and market data is more and dense, the cache space of the application is larger. It will be appreciated that the requested cache space should be smaller than the reserved cache addresses due to some auxiliary data or address failure issues. In addition, the management of the memory is managed in a paging mode, and in the prior art, the default page table of the operating system is 4KB, and a maximum large page of 2MB is supported. In step S11, the size of the cache space is related to the reserved cache address, the larger the cache address is, the more the cache space is, the larger the page table supported by the operating system is, and after the page table becomes larger, the more information that can be stored in each page is, so as to reduce the number of page tables, reduce the required address Translation, reduce the cache invalidation times of the Translation Lookaside Buffer (TLB), improve the access performance of the memory, and reduce the pressure of the CPU.
S12: and storing the market data into a cache space so as to be taken out by the server conveniently.
S13: and if the market data sent by the hardware equipment is not acquired within the preset time, releasing the cache space.
In step S13, when the cache space is no longer used, the cache space needs to be released for use again. In this embodiment, determining when the cache space is no longer used is performed by determining whether to obtain the market data sent by the hardware device again within a preset time. In other embodiments, the buffer space may also be released through operations such as closing an operation interface and the like by active operations of the user.
Compared with the prior art, the communication method of the market data, compared with the prior art, the continuous cache space is insufficient, and the sufficient cache space cannot be applied for storing the data, by adopting the technical scheme, the cache address can be reserved after the memory is initialized, after the market data sent by the hardware equipment is received, the cache space can be applied according to the reserved cache address and the sending density of the market data, because the cache address is a well-reserved and continuous address, the space can not be occupied by other data, the applied cache space can be released after the data is not received any more, the cache space can still be applied from the reserved cache address in the subsequent use, so that the probability of the continuous space which can be applied is higher, and more market data can be stored.
The cache address in this embodiment is reserved in advance, and a large number of experiments show that the lower the address of the memory is, the faster the data transmission efficiency is.
Therefore, on the basis of the above embodiment, in the present embodiment, the cache address is a low address.
In this embodiment, the reserved cache address is selected as a low address in the memory, and the transmission efficiency of the market data can be improved compared with that of a high address.
In a specific implementation, the market data is stored in the cache space, which is usually the protocol nodes stored in the cache space, and when one protocol node is filled with the market data, the server can take the data from the protocol node. It can be understood that, after the size of the cache space is fixed, the smaller the size of each protocol node is, the larger the number of protocol nodes is, the easier each protocol node is to be filled, and the server can more quickly fetch data from the protocol node filled with market data.
Therefore, on the basis of the above embodiment, in this embodiment, after the step of applying for the buffer space according to the buffer address reserved in advance and the sending density of the market data, the method further includes:
configuring the size and the number of protocol nodes in a cache space according to the sending density of the market data;
correspondingly, the storage of the market data into the cache space is as follows: and storing the market data into the protocol node of the cache space.
It is understood that after applying for the cache space, the protocol node may be configured. The configuration of the protocol nodes in this embodiment is also related to the sending density of the market data, and when the sending density of the market data is high, the data transmission pressure is high, so that the size of the protocol nodes is reduced, the protocol nodes are filled as soon as possible, the data can be taken by the server in time for subsequent transmission of other market data, and data loss is avoided.
In the above embodiment, it is described that the market data may exist in the protocol nodes, in a specific implementation, the hardware device receives market data from each region, and one market data may exist in the same protocol node or be divided into a plurality of protocol nodes.
Therefore, on the basis of the above embodiment, in this embodiment, the method further includes:
and judging whether the market data are completely written into the current protocol node, if so, marking the market data in the current protocol node by the actual length of the market data, and if not, marking the market data in the current protocol node by the characteristic value.
In a specific implementation, the length of the data is counted, in this embodiment, 0 is used as a characteristic value, when the market data fills up the current protocol node and partial data still exists in the next protocol node, 0 is used to mark the market data in the current protocol node to represent that the data is incomplete, and the length of the market data is used to mark the next protocol node to represent that the data is complete.
In this embodiment, by marking the market data in the protocol node, it is identified whether the market data taken from the current protocol node is all data.
In the embodiment, whether the market data in one protocol node is complete is identified through the characteristic value, and in specific implementation, after the protocol node marked with the actual length of the market data is received, whether all protocol nodes occupied by the market data are received needs to be judged.
On the basis of the foregoing embodiment, in this embodiment, after the step of determining whether the market data is written in all the current protocol nodes, the method further includes: and comparing whether the number of the protocol nodes occupied by the quotation data acquired from the hardware equipment and the quotation data extracted from the server is consistent or not, and if not, discarding the quotation data.
In this embodiment, the number of the protocol nodes occupied by the market data is counted, and the protocol nodes occupied by the same market data can be marked through the labels. And the cache of the market data in the protocol node is considered to be cached in a cache ring mode, namely, after the market data fills the cache ring, the covering cache is carried out from the beginning. When a market data is huge, a buffer ring may not be enough to transmit the whole market data, and the characteristic value and the actual length at this time cannot represent the integrity of the data, so the number of the buffer rings occupied by the market data needs to be counted during the statistics. And comparing whether the number of the protocol nodes occupied by the market data acquired from the hardware equipment and the market data taken out from the server is consistent or not by combining the number and the mark of the occupied cache rings so as to verify whether the market data is complete or not.
According to the communication method of the market data, the number of the protocol nodes occupied by the market data acquired by the hardware equipment and the market data taken out by the server is compared, and whether the data is complete or lost in the transmission process is judged.
In the foregoing embodiment, it is determined whether the market data is complete by counting the number, and in this embodiment, whether the market data acquired from the hardware device and the number of the protocol nodes occupied by the market data extracted by the server are consistent further includes:
and judging whether the protocol node is a continuous node or not, and if not, discarding the market data.
In this embodiment, after the number of the protocol nodes is consistent, it is further determined whether the protocol nodes are consecutive nodes, so as to avoid loss of market data due to simultaneous errors of the hardware device and the server, and further ensure integrity of the data.
In particular implementations, after a protocol node is fetched by a server, the protocol node may continue for subsequent use and the market data may be re-imported by the hardware device.
In this embodiment, the method further includes:
and sending a transmission notice to the hardware equipment under the condition that the server takes the data at the preset protocol node.
According to the communication method of the market data provided by the embodiment, after the server takes the market data, the server sends a transmission notice to the hardware device so as to reuse the protocol node to transmit the data.
In the above embodiments, the communication method of the market data is described in detail, and the present application also provides embodiments corresponding to the communication device of the market data.
