An electronic gaming machine (EGM) implements a multi-core processor. A first of the processor cores is adapted to perform or otherwise control a first set of operations. The first set of operations can include, for example, game manager operations and other operations of the EGM that are more time-sensitive. A second one of the processor cores is adapted to perform or otherwise control a second set of operations. The second set of operations can include, for example, operations related to multimedia presentation associated with the running/playing of a game and/or other operations of the EGM that are not time-sensitive or are otherwise less time-sensitive than the operations performed/controlled by the first processor core. Each of the processor cores may run an operating system that matches the needs of its respective processor core.
