Remote loading system based on FPGA and downloading configuration method thereof

Abstract

The invention discloses a remote loading system based on an FPGA and a downloading configuration method thereof, the remote loading system comprises a PC, the FPGA, a DDR and a FLASH, and the FPGA respectively communicates with the PC, the DDR and the FLASH for data interaction; and the FPGA comprises a UDP_ctrl module, a DDR_ctrl module, a FLASH_ctrl module and an ICAP_ctrl module. When configuration is downloaded for a loading system, firstly, a bit stream file generated by engineering is packaged into a. Bin file; the. Bin file data is written into an FPGA through an Ethernet UDP Protocol, then the. Bin file data is written into a DDR through the FPGA, and thus caching the data in the DDR; then, the FPGA reads out and writes the configuration data in the DDR into the FLASH, and the FLASH needs to be erased before writing; and finally, the FPGA actively reads the configuration data in the FLASH through the ICAP primitive to complete the reconfiguration of the FPGA.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an FPGA-based remote loading system and a download configuration method thereof. Background technique [0002] The current FPGA configuration methods can be divided into three types: active configuration, passive configuration and JTAG configuration. Generally, everyone is accustomed to using JTAG to update FPGA configuration, because JTAG configuration is very fast and convenient, and the integrated design tools of major manufacturers also provide corresponding JTAG configuration channels. However, JTAG configuration is only a general configuration method used in the debugging stage after all. After the FPGA engineering verification is completed, it is not suitable for applying to the corresponding products, because many products are released due to the cumbersome JTAG interface and product packaging requirements. , resulting in products that do not provide a JTAG interfac...
