Computing device for transceiving information via plurality of buses, and operating method of the computing device

A bus matrix, comprising:

• a first bus connected to a storage device and configured to transceive address information comprised in a first address map of particular address maps;
• and
• a second bus connected to the storage device and configured to transceive address information included in a second address map of the particular address maps,
• wherein the first bus is configured to store, in the storage device, object information received from an external storage device and mapped to a first address included in the first address map,
• wherein the second bus is configured to provide the object information from the storage device to a host device, in response to the object information being requested from the host device based on a second address that is separate from the first address and included in the second address map.

An operation method of a computing device that includes a host device and a storage device, the operation method comprising:

• receiving object information, to which an object data address comprised in a data address map of particular address maps has been mapped, from an external storage device via a system bus;
• storing the object information in the storage device;
• requesting an object code address comprised in a code address map, from the host device to the storage device;
• and
• providing the object information from the storage device
• to the host device via a code bus that is separate from the system bus in response to the request.
