Abstract

The invention relates to an FPGA-based USB data real-time monitoring system and method, belonging to the technical field of electronics and communication. The present invention includes FPGA chip, USB transceiver module I, USB transceiver module II, DDR3 SDRAM memory; FPGA chip includes: ULPI data transceiver module I, ULPI data transceiver module II, ULPI control module I, ULPI control module II, data temporary memory module and FPGA signal processing and coordination module. In the present invention, the FPGA is used for relay, and the data on the USB bus can be unpacked, stored, and forwarded after being connected to the USB transmission line without a PC, so as to realize real-time monitoring and collection of non-invasive USB data from the data level. .

Description

technical field [0001] The invention relates to an FPGA-based USB data real-time monitoring system and method, belonging to the technical field of electronics and communication. Background technique [0002] FPGA (Field-Programmable Gate Array), the full name is Field Programmable Gate Array. It emerged as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of original programmable device gates. The circuit design completed in hardware description language (Verilog or VHDL) can be quickly burned into FPGA for testing through simple synthesis and layout, which is the mainstream technology of IC verification. FPGAs can be produced quickly, can be modified to correct errors in the program and are cheaper to manufacture. At the same time, FPGA can realize a lot of logic functions. Due to the flexible and changeable internal str...
