Abstract

The embodiment of the invention provides a loading method and a device of a field programmable gate array. The loading method comprises the following steps: receiving a control command, wherein the control command is corresponding to a requested loading mode; communicating a passage between a loading interface of the field programmable gate array and a loading mode interface of the corresponding requested loading mode; and transmitting the requested loading mode to the field programmable gate array through a mode selection interface of the field programmable gate array so as to be convenient for the field programmable gate array to load according to the loading mode. Through the method and the device, a corresponding loading mode can be selected according to the type of a loading mode and a loading mode interface of a main control device so as to freely select a loading or debugging mode to of a FPGA device and solve the problems of no matching and inconvenient matching of a development project caused by consistent loading mode of the FPGA device.

Description

technical field [0001] The invention relates to a field programmable gate array, in particular to a loading method and device for a field programmable gate array. Background technique [0002] At present, FPGA (Field Programmable Gate Array, Field Programmable Gate Array) devices have many loading modes, such as: JTAG (Joint Test Action Group, boundary scan technology), AS (Active serial, serial loading mode using external FLASH), AP (Active parallel, parallel loading mode using external FLASH), PS (Passive serial, serial loading mode using external devices), FPP (Fast passive parallel, parallel loading mode using external devices), etc., many companies Or the project team will choose a certain method to load the FPGA according to their current resources. [0003] The inventor found that if you encounter a cooperative project, such as a project developed by several parties at the same time, you need to verify whether your code or program meets the requirements at the beginn...
