A kind of fpga automatic loading system and method

Abstract

The invention discloses a system and method for FPGA automatic loading, and particularly relates to multiple FPGA loading modes of a Norflash. The Norflash and TCP / IP network technology is adopted and multiple FPGA codes in a base station are automatically loaded. The method includes the steps that the FPGA codes are downloaded to a Norflash designated storage position of a base station device from a server through a network; when the base station is started again, the loading procedure of one or more FPGAs is logically controlled through a CPLD, an FPGA image configuration file is read from the Norflash designated storage position, and the loading process is started. According to the method, the different FPGAs can be automatically loaded in the base station device of a computer room of an operator and the FPGA codes can be correctly, rapidly and efficiently loaded at any time without cables.

Description

technical field [0001] The invention relates to an FPGA automatic loading system and method, in particular to a multiple FPGA (Field Programmable Gate Array) loading mode of Nor flash (non-volatile flash memory). Background technique [0002] As the amount of wireless communication data continues to increase, FPGAs play an important role in base station products, especially for more and more complex data processing, so the need for convenience in FPGA code loading and upgrading will become more and more obvious . [0003] In the past, the debugging and loading of FPGA programs all used special downloaders launched by various FPGA manufacturers. Using downloaders is not only expensive, but also has high requirements for the use environment, and is easily damaged during live online debugging. When downloading the program, it is necessary to connect the PC (personal computer) to the FPGA locally through the USB (universal serial bus) download cable. Once the product is assembl...

Problems solved by technology

[0003] In the past, the debugging and loading of FPGA programs all used special downloaders launched by various FPGA manufacturers. Using downloaders is not only expensive, but also has high requirements for the use environment, and is easily damaged during live online debugging.

When downloading the program, it is necessary to connect the PC (personal computer) to the FPGA locally through the USB (universal serial bus) download cable. Once the product is assembled, the loading process will be very troublesome when modifying and upgrading the FPGA program. The program update can only be realized by connecting the download cable after dismantling the package locally; however, this process is inflexible and inefficient, especially in the upgrade of new base station equipment.
