A remote transmission loading multi-node FPGA program loading management circuit

Abstract

The invention discloses a remote transmission loading multi-node FPGA program loading management circuit, and aims to provide an FPGA loading circuit which is high in dynamic configuration speed and stable and reliable in remote loading. The invention is realized through the following technical scheme that the main control upper computer is connected with a plurality of PS nodes of the extensibleprocessing platform ZYNQ through the Ethernet switch; a PS node of the ZYNQ is connected with a PL node of the ZYNQ through an AXI4 bus, and the PL node of the ZYNQ is connected to an FPGA node to beloaded through a special configuration interface circuit to form a remote loading circuit; a PL node of ZYNQ manages a plurality of FPGA nodes to be loaded, and based on an open-source application container engine Docker mirror image, the FPGA mirror image is packaged into the Docker mirror image; and the loading program reads the FPGA mirror image file in the engine container Docker, transmits the FPGA mirror image data to the ZYNQPL node, and loads and starts the FPGA of the corresponding node after the ZYNQPL node receives the FPGA data.

Description

technical field [0001] The invention relates to a complete set of FPGA program loading and storage scheme and loading and reloading circuit formed by combining the Internet virtual technology field and the embedded platform management field. Background technique [0002] In recent years, FPGA, a powerful platform, has made the hardware configuration of each node of a multi-node system more versatile. Especially with the promotion of IP core technology and the emergence of some powerful CPU cores, the main functions of many current systems can be realized by large-capacity FPGAs without the need to use more expensive high-performance microprocessors. device. For nodal systems, this will greatly reduce system cost. For a multi-node system composed of large-capacity FPGAs, system upgrade is a time-consuming and labor-intensive task. At this time, the remote upgrade capability of FPGA is particularly important. For multi-node systems including ARM, DSP, PoerPC and other high...

Problems solved by technology

This method has the following characteristics: Advantages: FLASH has a large capacity and can store up to dozens of versions; Disadvantages: the loading speed is slow, the loading speed is in seconds, the loading depends on many devices, and the reliability is low

This method has the following characteristics: advantages: fast loading speed, the loading speed is in milliseconds, and relatively few devices are dependent on loading; disadvantages: limited loading version, one PROM has 4 versions

Advantages of this method of loading: 1. The loading circuit is provided and implemented by the manufacturer, and the circuit is stable and reliable; Disadvantages: Batch program upgrades cannot be performed, and the service personnel need to open the product cover to upgrade the FPGA node at the foreign minister, and upgrade through the JTAG port. The efficiency is very low, and it also requires the service personnel to have professional embedded knowledge

[0008] (2) Transfer the FPGA image file to the FLASH corresponding to the FPGA, and the FPGA reads the data in the FLASH for loading. This method has advantages: compared with method (1), the loading speed is improved; disadvantages: 1. Each FPGA needs to be equipped with a FLASH memory, increase cost

[0009] (3) Only one FPGA image can be stored at a time, and it takes a lot of time to switch programs each time, which is not conducive to fast program switching
