method for realizing remote upgrading of an FPGA program based on a ZYNQ chip

Abstract

The invention discloses a method for remotely upgrading an FPGA (Field Programmable Gate Array) program based on a ZYNQ chip. The related main devices comprise a zynq chip, an FPGA chip, a QSPI (QuadSerial Peripheral Interface) storage chip, an EMMC (Enhanced Media Card) storage chip and a DDR3 (Double Data Rate 3) memory chip. Program upgrading, the PC is connected with the ZYNQ through the Ethernet; the program is transmitted from the PC end to the ZYNQ external EMMC storage chip for storage; Each time the device is powered on, The application program in the PS of the ZYNQ moves the FPGA program in the EMMC storage chip to the PL part of the ZYNQ, the transmission logic of the SelectMap is compiled in the PL, and the program can be transmitted to the FPGA from the PL part through a SelectMap method so as to be started. The data migration from the EMMC storage chip to the PL is realized in the DDR3 externally matched with the ZYNQ after the mapping from the physical address to the virtual address is completed. According to the method, remote upgrading of the equipment can be realized.

Description

technical field [0001] The invention relates to a method for realizing remote upgrading of FPGA programs based on a ZYNQ chip, which is suitable for performing high-speed data processing on the FPGA and performing remote program updating and normal startup configuration on the FPGA when the ZYNQ is used as the main control. Background technique [0002] With the development of technology, it is necessary to update and upgrade the original program of the device to add new functions or fix bugs. FPGA devices usually have three program download methods: JTAG method, active configuration method, and passive configuration method. JTAG is usually used for debugging. The active configuration method is that the FPGA acts as a controller every time it is powered on, and the FPGA device guides the configuration operation process. It controls the external memory and the initialization process, and actively reads data from the storage device. This configuration method needs to occupy ...

AI Technical Summary

Problems solved by technology

Using a pure ARM processor, if you do not want to occupy FPGA resources, you need to complete all the transmission configuration logic in the application layer program of the processor. Although this method can also achieve remote upgrades, the complete application layer transmission efficiency is low
