1. An electronic device, comprising: a processing array including a plurality of processing cores, the processing component being configurable for one of a single-core processing mode and a multi-core processing mode, wherein the single-core processing mode comprises the processing array configured to execute an operating system in a first operating system mode using a first one of the processing cores, wherein the first operating system mode is optimized to perform a single task, and wherein the multi-core processing mode comprises the processing array configured to execute the operating system in a second operating system mode using the first one of the processing cores and a second one of the processing cores, wherein the second operating system mode is optimized to perform multiple tasks; and a task manager determining a number of user-operated tasks running on the electronic device, wherein the processing array is configured to operate in the single-core processing mode or the multi-core processing mode based only on the number of user-operated tasks, wherein the processing array operates in the single-core processing mode when the number of user-operated tasks is one and operates in the multi-core processing mode when the number of user-operated tasks is greater than one, wherein the single-core processing mode enables only the single task to be executed and disables a multi-core processing architecture.
