Abstract
Provided is a multi-core device. The multi-core device includes: a plurality of cores outputting a test response value by receiving a test pattern value; a majority analyzer outputting a value corresponding to a majority of the test response value by analyzing the test response value; and a determination unit determining a core outputting a test response value different from the value corresponding to the majority among the plurality of cores.

A multi-core device comprising:
- a plurality of cores outputting a test response value by receiving a test pattern value;
- a majority analyzer outputting a value corresponding to a majority of the test response value by analyzing the test response value;
- and
- a determination unit determining a core outputting a test response value different from the value corresponding to the majority among the plurality of cores.
