Method and device for quickly programming FPGA (Field Programmable Gate Array) firmware, equipment and readable medium

Abstract

The invention provides a method and a device for quickly programming FPGA firmware, equipment and a readable medium. The method comprises the following steps of: judging whether received data is a firmware upgrading instruction or not; in response to the fact that the received data is a firmware upgrading instruction, erasing the data to be written into firmware at this time and caching the subsequently received data; in response to the fact that the cached data reach the threshold value, starting to write all the cached data into firmware; and in response to completion of writing all the cached data into the firmware, reading the data written into the firmware, and judging whether firmware programming succeeds or not according to the read data. By means of the scheme, fast programming of the FPGA firmware can be achieved, the programming speed of the firmware is greatly increased, meanwhile, the programming flexibility of the FPGA firmware is improved, and the method and device can be effectively applied to application scenes with special requirements for space and time.

Description

technical field [0001] This field relates to the computer field, and more specifically relates to a method, device, device and readable medium for fast programming of FPGA firmware. Background technique [0002] The full name of FPGA is Field Programmable Gate Array. The chip contains a wealth of programmable logic units and wiring resources. The internal logic units and interconnection structure can be configured and changed by software to complete the established design functions. FPGA has high reliability, high parallel processing capability and flexible programmability, and is widely used in communication, medical treatment, industrial Internet, etc. [0003] According to different FPGA implementation processes, it can be divided into FPGAs based on SRAM structure, FPGAs based on antifuse structure, and FPGAs based on Flash structure. Among them, the FPGA based on the SRAM structure is widely used because of its low cost, large-scale integration, and high performance. C...

AI Technical Summary

Problems solved by technology

Limited by the low data transfer rate of JTAG, the firmware programming time of large-scale FPGAs is generally more than 20 minutes, and the USB-JTAG download line is easily disturbed by the outside world, resulting in the failure of firmware programming, which seriously affects the FPGA firmware. programming efficiency

In some special applications, when the whole machine has strict requirements on the firmware programming time or the JTAG download line cannot be connected, this traditional firmware programming method cannot meet the requirements.
