Multisystem and method of booting the same

A first core connected to a second core, the first core comprising:

• a first boot loader execution unit configured to execute a boot loader of the first core;
• a network activation unit configured to set a network interface of the first core to be in an enable state;
• a device detector configured to detect the second core that is connected to the network interface of the first core;
• a memory mapping unit configured to map a first memory of the first core to a second memory of the second core;
• a booting image loading unit configured to load a booting image of the first core and a booting image of the second core on the first memory;
• and
• a booting image transfer unit configured to transfer the booting image of the second core loaded on the first memory to the second core via a network.

A second core connected to a first core, the second core comprising:

• a second memory mapped to a first memory of the first core and configured to load the booting image of the second core transferred from the first memory;
• a second boot loader execution unit configured to execute a boot loader of the second core included in the booting image of the second core in response to a booting register of the second core being set to be in an enable state by a booting register setting unit of the first core;
• and
• a second booting unit configured to boot a kernel of the second core based on the booting image of the second core.
