Abstract

The invention provides a method and system for upgrading a programmable logic device. The system includes a CPU, multiple programmable logic devices and on-off control circuits corresponding to the number of programmable logic devices. When the CPU upgrades a programmable logic device , turn on the enabling of the on-off control circuit connected to the programmable logic device to be upgraded, and turn off the enabling of each on-off control circuit connected to other programmable logic devices; load the obtained upgrade file into the In the programmable logic device, the programmable logic device is upgraded. Because in the present invention, by controlling the enabling of the on-off control circuit, the upgrade of each corresponding programmable logic device is realized, and only one programmable logic device needs to be driven each time, without considering the limitation of driving capability.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and system for upgrading a programmable logic device (Programmable Logic Device, PLD). Background technique [0002] Programmable logic devices are widely used because they can provide a wide variety of logic capabilities, characteristics, speed and voltage characteristics. For example, multiple programmable logic devices can be used on one node device. On devices that use many programmable logic devices, such as node devices, it is necessary to upgrade multiple programmable control devices in the device to avoid a certain vulnerability (BUG). [0003] When upgrading the multi-chip programmable logic devices in the device, remote operation can be performed through the serial port, USB port or Ethernet port in the device. The specific upgrade process includes: the central processing unit (CPU) in the node device will The logic code for upgrading the programma...
