Problems solved by technology

For the continuous uninterrupted movement process, such as the optical fiber is arranged in the drag chain and moves continuously with the receiving end, the probability of packet error will be greatly increased due to the packet loss caused by the bending of the optical fiber during the movement
[0008] 3. The graphic data processing of the PC layer is performed on different PCs, and TCP / IP communication is adopted between different PCs, so there is a delay and the data processing time is relatively long

Embodiment 1

[0033] This embodiment provides a data processing system, see figure 1 , the system includes: an industrial computer, a graphics accelerator card, a communication board and a driver board; the graphics accelerator card, the communication board and the driver board are boards based on FPGA chips.

[0034] like figure 1 As shown, the CPU of the industrial computer is used for task scheduling at the control level and the user interface level; the graphics accelerator card is inserted in the motherboard pcie slot of the industrial computer in the form of a pcie interface, and its main function is to assist the CPU in hardware acceleration of graphics data Processing to improve data processing capability and processing delay. The communication board is inserted into the pcie slot of the mainboard of the industrial computer in the form of a pcie interface. The main function is to convert the data format, convert the pcie data format into a communication data packet format and send ...

Embodiment 2

[0040] This embodiment provides a data processing method, the method comprising:

[0041] Step 1: The CPU of PC1 receives the original graphics and graphics transformation parameters from PC2, and performs corresponding graphics transformation on the original graphics according to the received original graphics and graphics transformation parameters (rotation, translation, expansion and contraction parameters, etc.).

[0042] Step 2: The CPU of PC1 cuts the original graphic into pieces according to parameters such as the positional relationship (L1, L2, ..., Ln) between each DMD, the stripe width (the stripe width is also the width of the Block block) and the height of the Block block. Graphic blocks related to DMD, that is, a graphic is divided into block graphics, and these block graphics are combined to form a complete graphic. like Figure 5 shown;

[0043] Step 3: The CPU debugs the segmented block graphics to the graphics accelerator card, and the graphics accelerator ...

Abstract

The invention discloses a data processing system and method, and belongs to the technical field of exposure. According to the system, a graphic acceleration card, a plurality of communication board cards and a driving board card are integrated on an industrial personal computer, wherein the graphic acceleration card performs vector transformation or bitmap transformation according to Block block graphs; multiple modules are instantiated in the FPGA for parallel synchronous processing, serial execution like CPU processing is not needed, the processing rate is increased, the processing time delay is shortened, and therefore the problems that in the past, the data processing capacity is insufficient, multiple PCs are needed, and the data processing time delay is long are solved; through the communication board card, the transmission rate is improved, and one pcie data processing board can carry out 10Gbit / s data transmission on N receiving ends, so that more receiving ends can be supported to carry out data transmission at the same time under the condition that pcie slots are not increased. Due to the fact that the multiple communication board cards are arranged, data transmission can be achieved in a network cable mode, and the requirement for equipment wiring is lowered.

Description

technical field [0001] The invention relates to a data processing system and method, belonging to the field of exposure technology. Background technique [0002] Laser direct writing exposure equipment is a device that digitally processes user graphics and transmits them to the graphics generator, and cooperates with worktable movement and optical imaging principles for exposure. Digital processing and transmission of graphics is a very important link. As equipment has higher and higher requirements for graphics accuracy, the data volume of graphics has also become larger and larger, and the data processing capability and transmission rate will gradually become the bottleneck restricting production capacity. [0003] At present, in the laser direct writing exposure equipment, the processing of graphic data will be processed on several different levels, and each level will be in a different physical location of the equipment, so the graphic data of different levels inevitably...
