Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0019] This device is a carrier board including ZYNQ-030 main control chip and four AMC slots. Each AMC slot is inserted with an AMC board. Each AMC board has two Xilinx K series FPGA chips (K325t and K410t) and one STM32F429 control chip, each FPGA chip and STM32F429 control chip realize the SelectMap interface through 13 GPIOs, the AMC cards in the four slots are exactly the same, each STM32F429 control chip and ZYNQ-030 main control chip are connected through lanswitch LAN switching chip connection, the interface is TCP. These units constitute the hardware platform of the present invention, such as figure 1 shown.

[0020] The framework of the present invention is controlled by the ZYNQ-030 main control chip in the host computer, and the STM32F429 control chip on each AMC board is controlled by the ZYNQ-030 main control chip, and the STM32F429 control ch...

Abstract

The invention discloses multi-signal processing equipment and a remote upgrading method thereof for a FPGA program. The equipment is a bearing board card with a ZYNQ master control chip and four AMC slots, an AMC board card is inserted into each AMC slot, and two FPGA chips of the Xilinx company and a STM32 control chip are arranged on each AMC board card, the FPGA chips and the STM 32 control chip are connected through a SelectMap interface; four STM32 control chips are respectively connected with a lanswitch local area network switch chip through a TCP interface, the lanswitch local area network switch chip is respectively connected with the ZYNQ master control chip and an upper computer through the TCP interface. The program remote downloading of the FPGA chip in the K series of the Xilinx company is realized, the trouble that the maintenance personnel has to update the program to the site is avoided, and an external interface is saved for the equipment.

Description

technical field [0001] The invention relates to the field of embedded Ethernet communication and special-purpose interface communication with FPGA, in particular to a multi-signal processing device and its remote upgrade method for FPGA program. It specifically involves the TCP large data volume communication between the STM32 chip and the operating system and the program download interface between the STM32 and the FPGA. Background technique [0002] The program upgrade of FPGA is generally completed by downloading the program with a dedicated programmer. In this case, it is generally necessary to enter the site and directly connect with the device, and the device needs to reserve a dedicated interface during design. Or use third-party specialized software to upgrade through a dedicated interface. Due to the limitations of tools, it is difficult to perform remote upgrades. Sometimes the on-site environment is quite special, it is difficult to enter or the special requireme...
