Electronic device, and method for controlling same

A method for controlling an electronic device comprising a plurality of processors, the method comprising:

• receiving, through a second interface circuit in a processor of the plurality of processors, a bus command of a second interface scheme comprising a security indicator;
• converting address information in the received bus command to comprise security information;
• and
• outputting, to a first interface circuit in the electronic device, by converting the received bus command comprising the converted address information through a first interface scheme.

A method for controlling an electronic device comprising a plurality of processors, the method comprising:

• receiving a bus command of a first interface scheme;
• confirming security information of the bus command based on a pre-set bit location from among a plurality of bits that configure address information in the received bus command;
• removing the security information from the address information based on determining that the bus command is confirmed as information requiring security;
• and
• converting and outputting the bus command, based on determining the bus command as having a security indicator indicating that the bus command is a request requiring security, and the address information, with the security information removed, through a second interface scheme.
