Claim 6:
7. An online upgrade method for a multi-core embedded system,
wherein the multi-core embedded system is connected to a service system providing upgraded firmware files through a communication module, wherein the method comprises:
mapping, by the programmable logic module, the memory of the multi-core embedded processor system to the service system, wherein the multi-core embedded processor system shares a register module with the programmable logic module; and
when the multi-core embedded system receives the upgrade firmware files sent by the service system, obtaining, by the multi-core embedded processor system, the upgrade firmware files through memory, and realizing the online upgrade of the multi-core embedded system,
wherein the programmable logic module maps the memory of the multi-core embedded processor system to the service system through the switch of an external PCI-Express bus and an internal AXI4 bus.
