Electronic device including hardware architecture for supporting inter-process communication and method for performing inter-process communication

As one aspect of the present disclosure, an electronic device is disclosed. The device includes: a plurality of clusters, wherein each of the plurality of clusters comprises a plurality of cores; mailboxes uniquely corresponding to each of the plurality of clusters; and a system bus, wherein the inter-process communication may be performed between a sending core and a receiving core of the plurality of cores, and if the sending core and the receiving core are included in the same cluster, a mailbox corresponding to the same cluster may be configured to perform the inter-process communication without going through the system bus, and if the sending core and the receiving core are included in different clusters, mailboxes corresponding to each of the different clusters may be configured to perform the inter-process communication via the system bus.
