This paper discusses the chief techniques and design principles of an ultra-high speed and dual-channel data acquisition card based on PXI bus, using FPGA (Field Programmable Gate Array) as logic controller cell. The instrument consists of pre-process circuit, A/D converter, SDRAM (Synchronous Dynamic random access memory), and control circuit integrated in FPGA. It can achieve allowing up to 1000MHz real-time sampling rate. The test result indicates that the system works normally and the system design is successful.

Asynchronous Parallel

A high-speed data acquisition card using USB 3.0 interface has been designed in order to solve the problem that traditional data acquisition card could not take both data transmission bandwidth and easy connection with PC into account. The data acquisition card controlled the dual-channel 12-bit 20Msps ADC for asynchronous parallel sampling using FPGA as core control module, which made the sampling rate up to 40Msps. The sampled data which was processed by FPGA transferred synchronous from FIFO interface to PC via USB controller. The basic structure of hardware and the basic design method for software and firmware were given in this paper, in which how to use FPGA to realize FIFO was elaborated in detail. The timing simulation of using asynchronous parallel A/D conversion technology and using ADC device of 40Msps sampling rate for FIFO internal data transmission were simulated respectively, thus verified the reliability of asynchronous parallel A/D conversion.

To improve data transmission performance of the data acquisition card, a design of high-speed data transmission system is proposed in the thesis. Using FPGA of programmable logic devices, adopting Verilog HDL of hardware description language, the design of modularization and DMA transmission method is implemented in FPGA. Eventually the design implements the data transmission with high-speed through PCI Express interface. Through simulation and verification based on hardware system, this design is proved to be feasible and can satisfy the performance requirements of data transmission in the high-speed data acquisition card applied in high-speed railway communication. The design also has some value of application and reference for a universal data acquisition card.

Acquisition Technique

Data acquisition is the most demanding application for the acquisition and monitoring of various sensor signals. The data received are processed in real-time environment. This paper proposes a novel Data Acquisition (DAQ) technique for better resource utilization with less power consumption. Present work has designed and compared advanced Quad Data Rate (QDR) technique with traditional Dual Data Rate (DDR) technique in terms of resource utilization and power consumption of Field Programmable Gate Array (FPGA) hardware. Xilinx ISE is used to verify results of FPGA resource utilization by QDR with state of the art DDR approach. The paper ratiocinates that QDR technique outperforms traditional DDR technique in terms of FPGA resource utilization.
