With the development and popularization of microelectronic technology, more and more electronic engineering personnel adopt Programmable Logic Devices (PLDs) to realize their electronic products, so that the time to market of the products is shortened, the performance and reliability are greatly improved, and the cost of the whole machine is reduced; because most PLDs are one-time programmable, it is difficult to modify or upgrade the functions of a programmable logic device after it is installed on a circuit board.
In recent years, an In-System Programmable (ISP) logic device has appeared, and this ISP technology can redefine the logic functions of the logic device, circuit board and the whole System before, during or after the generation and supply of electronic products, so that the hardware design is as flexible as software and easy to modify, which not only greatly simplifies the design and production flow, but also brings great convenience for the upgrade service of the products.
Referring to fig. 1, generally, PLD logic is based on a Static Random Access Memory (SRAM) architecture, and a storage space similar to a flash Memory 102a (flash) is also provided inside a programmable logic device 102 (PLD). The method for upgrading the PLD logic is as follows: an external updating device 101 sends a target file to the PLD, wherein the target file is created according to the standard of Joint Test Action Group (JTAG) and comprises a command for updating the content of the flash (102a), the content needing to be updated and a command for updating the content of the flash (102a) to the logic 102b based on the SRAM PLD; the PLD receives the update message, reads a command for updating the flash (102a) content and then updates the content to be updated into the flash (102 a); after reading the command of updating the content of the flash (102a) to the SRAM PLD logic 102b, the content of the flash (102a) is updated to the SRAM PLD logic 102b, thereby realizing the upgrading of the PLD system.
The inventor finds the following problems in the prior art in the process of implementing the invention: because the PLD and the system reset have strong correlation, the system needs to be restarted after the upgrading of one PLD is finished, and then the upgrading of another logic can be carried out, so that when a plurality of PLD programs need to be upgraded, the system needs to be restarted for many times, the repeated restarting takes long time, and the restarting can interrupt service, thereby causing poor user experience.
