Abstract

The invention provides a USB (universal serial bus) flash drive type FPGA (field programmable gate array) development board comprising a selector key, a USB interface, and a circuit board. The selector switch is used for controlling the USB flash drive type FPGA development board to switch between a USB mode and a development board mode. The circuit board connected with the selector key and the USB interface is provided with a USB unit and a development board unit. The USB unit connected with the USB interface and the selector key is used for allowing the USB flash drive type FPGA development board to switch between the USB mode and the development mode according to action of the selector key. The development board unit comprises an FPGA chip, a JTAG (joint test action group) interface, and a plurality of learning components connected with the FPGA chip. The FPGA is connected with the USB unit. The JTAG interface is connected between the USB interface and the USB unit. The USB flash drive type FPGA development board has smaller development board area, is portable and is more targeted.

Description

technical field [0001] The invention relates to a development board, in particular to a U disk-type FPGA development board. Background technique [0002] FPGA (Field-Programmable Gate Array), that is, Field Programmable Gate Array, is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. 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. Since its birth, it has been favored by electronic enthusiasts. In order to open up the market and expand the market share of FPGA, FPGA manufacturers have also increased cooperation with universities and related companies to conduct technical training and produce supporting development boards or development boards. However, compared with other electronic devices, the FPGA technology threshold ...
