The device comprises a field programmable gate array chip and a digital signal processor chip, wherein the field programmable gate array chip is provided with a first Flash memory for storing an FPGA updating program, the field programmable gate array chip is connected to an HPC pin of an FMC end through an LVDS interface, and the field programmable gate array chip is connected with a four-channel SFP interface through a GTH interface; the digital signal processor chip is connected with a PHY physical layer chip through an SGM interface, and the digital signal processor chip is provided with a second Flash memory for storing a DSP updating program; the field programmable gate array chip is connected with a CPLD complex programmable logic device through a GPIO interface, and the CPLD complex programmable logic device is connected with the digital signal processor chip through an EMIF interface. The user can maintain the equipment product and update the program remotely, so that the dependence on special equipment is reduced.

Description

technical field [0001] The embodiment of the present invention relates to a device and method for updating FPGA and DSP programs based on a network, in particular to a device and method for curing and updating programmable device programs on a hardware platform. Background technique [0002] Programmable logic device originated in the 1970s. It is a new type of logic device developed on the basis of application-specific integrated circuits (ASIC). It is the main hardware platform for digital system design today. Its main feature is that it is completely controlled by the user through software. Configure and program to complete a specific function, and can be repeatedly erased and written. When modifying and upgrading the PLD, there is no need to change the PCB circuit board, just modify and update the program on the computer, making the hardware design work a software development work, shortening the cycle of system design, improving the flexibility of implementation and red...

Problems solved by technology

[0003] In the prior art, it is necessary to use emulators of FPGA and DSP to realize program solidification and update of programmable devices (FPGA and DSP) on the hardware platform at the equipment site, so that when system equipment is maintained and updated It requires developers to be at the equipment site and use a dedicated emulator, which limits the working environment of test and maintenance personnel, and the working process is more complicated
