High-speed data adapter card device based on FPGA and corresponding method

Abstract

The invention relates to a high-speed data adapter card device based on an FPGA (Field Programmable Gate Array), which comprises an FPGA module for controlling other modules, a clock module connectedwith the FPGA module; an address module connected with the FPGA module; an SPI interface module connected with the FPGA module; an SDRAM module connected with the FPGA module; a USB module connected with the FPGA module; and a program downloading and debugging module connected with the FPGA module. The invention further relates to a corresponding method for achieving high-speed data switching control based on the FPGA. With the adoption of the FPGA-based high-speed data adapter card device and the corresponding method, the product is smaller in size, lower in price and more flexible due to theadoption of an FPGA-based hardware solution. The FPGA parallel processing structure enables data transmission to be faster, the hardware programming language enables system stability to be improved,maintenance and upgrading to be simpler based on the field programmable characteristic of the FPGA parallel processing structure, manpower is saved, unnecessary wiring troubles are avoided, and meanwhile the measurement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of communication measurement, in particular to the field of high-speed communication between a host computer and a plurality of DSPs, in particular to an FPGA-based high-speed data transfer card device and a corresponding method. Background technique [0002] With the continuous advancement of communication measurement technology and the vigorous development of the network communication industry, the use of traditional measuring instruments for measurement in the production process will result in fewer ports of measuring instruments, a small number of measuring products, and cable connections between measuring instruments and products. The problem of many times greatly reduces the efficiency of product production and quality verification. [0003] Due to the above problems, there is an urgent need for a large-scale measurement technology for products, and to achieve large-scale measurement of products, the m...

Problems solved by technology

[0003] Due to the above problems, there is an urgent need for a large-scale measurement technology for products, and to achieve large-scale measurement of products, the most important thing is to connect multiple measurement devices through a PC, so that the PC can quickly read and receive multiple measurement devices. The parameter information of a measuring device can control multiple measuring instruments, but if you use the USB interface of the PC itself, the result is that there are still few measuring instruments that can be connected, which will affect the production efficiency of the product. If you want to use the USB-HUB If it is connected, it will lead to complicated wiring and inconvenient wiring.
