Embodiment 1

[0023] figure 1 It is a connection block diagram of parallel data decoding device in the present invention, such as figure 1 As shown, the parallel data decoding device disclosed in this embodiment includes: a task allocation module, which is used to obtain the first address of the big packet header and send it to the data transceiver module; Assign a single-channel conversion module, and send the pairing information of the medium package and the single-channel conversion module to the data selection module at the same time; the data transceiver module is used to receive the first address of the big package header and extract the corresponding address from the RAM according to the first address of the big package header. The stored big bag is also used to send the extracted big bag to the data selection module; the data selection module is used to receive the big bag, and sends the big bag header in the big bag to the data processing module, and sends the middle bag in the big...

Embodiment 2

[0035] Such as image 3 As shown, this embodiment discloses a parallel data decoding method, which is used to implement parallel data decoding through the parallel data decoding device described in Embodiment 1, including: S1: the task allocation module starts decoding by obtaining the first address of the large packet header, and then converts the large packet The first address of the header is sent to the data transceiver module; S2: the data transceiver module extracts the big header stored on the corresponding address from the RAM according to the first address of the big header and sends it to the data selection module; S3: the data selection module receives the big header and sends it to Data processing module; S4: The data processing module parses the big header to obtain the big header information and sends the big header information to the task assignment module; S5: The task assignment module assigns a single packet to each middle packet according to the number of mid...

Abstract

The invention relates to the technical field of databases, in particular to a parallel data decoding device and method, and the device comprises a task distribution module which is used for obtaininga header address of a big packet header and transmitting the header address to a data receiving and transmitting module; wherein a single-channel conversion module is allocated to each medium packet;a data transceiving module used for extracting a big packet and sending the big packet to a data selection module; the data selection module used for sending the large packet header to the data processing module and sending the medium packet to the corresponding single-channel data conversion module; a data processing module used for analyzing the large packet header to obtain large packet headerinformation and sending the large packet header information to the task allocation module; and a plurality of single-channel conversion modules used for receiving the middle packets matched with the single-channel conversion modules and correspondingly decoding the data according to a coding rule. Data decoding can be achieved, multichannel parallel processing can be achieved, multi-channel data decoding can be completed at the same time, the transmission speed is high, and the efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a parallel data decoding device and method. Background technique [0002] With the increase of the amount of data, the delay of database access is getting bigger and bigger. Many tasks that were once easy to accomplish with traditional methods on small data are now very difficult on big data. At present, the fastest solid-state drive (SSD) storage can achieve a read speed of 12GB / s, but even at this speed, if the database has a size of 15TB, it still takes 33 hours to complete a query with a complete retrieval method. In order to speed up the database query speed, most of them use the method of designing a database-specific processor to improve performance. [0003] In the database-specific accelerator, data management is highly complex, and the data format to be processed is complex. In order to quickly process data and improve data processing efficiency, it is necessary to c...
