Field programmable gate array (FPGA) on-chip signal sampling device based on Ethernet transmission

The utility model relates to a field programmable gate array (FPGA) on-chip signal sampling device based on Ethernet transmission, which comprises a sampling control logic module, an Ethernet interface device and a computer which is used for receiving a sampling data stream, wherein the sampling control logic module, the Ethernet interface device and the computer which is used for receiving the sampling data stream are connected by using network cables or conducting wires. The FPGA on-chip signal sampling device based on Ethernet transmission has the advantages that a logic circuit is used for realizing the basic functions of a network card driver and a function of continuously sampling FPGA on-chip signal change data by using an Ethernet transmission method is realized; initialization and the filling and the transmission of frames are fully completed by hardware and do not rely on an operating system and a driver; data is transmitted by using the optimal mode of an Ethernet interface, average transmission sp
