Online upgrade system for multi-core embedded system
A recently granted patent (Publication Number: US11899612B2) discloses an innovative online upgrade system for a multi-core embedded system. The system comprises a service system and a multi-core embedded system, with the service system providing necessary upgrade firmware files. The multi-core embedded system includes a system on chip with a multi-core embedded processor system and a programmable logic module that maps memory to the service system. A communication module establishes a connection between the system on chip and the service system, while a register module facilitates control information interaction. A DMA module enables fast data transfer, and an interrupt controller triggers interrupt processing for online upgrades. The system utilizes external PCI-Express and internal AXI4 buses for mapping memory.
Furthermore, the patent details an online upgrade method for the multi-core embedded system, where the programmable logic module maps memory to the service system, enabling the multi-core embedded processor system to obtain upgrade firmware files for online upgrades. The method involves obtaining firmware files through memory, with the multi-core embedded processor system configuring memory addresses and receiving files based on file transmission status and type. Additionally, after obtaining the upgrade firmware files, the method includes writing them into embedded multimedia memory or flash memory based on the file type. This innovative system and method provide a seamless online upgrade process for multi-core embedded systems, enhancing efficiency and performance in embedded system upgrades.
