An Optimized Personal Computer (OPC) system may be a multi-functional processing unit with ultra-low power consumption and may consist of a single chip having a plurality of processors thereon. Each processor may be specialized for tasks including computing, graphic processing and audio processing. The OPC may be connected to a mother board, a memory unit and an I/O interface. The OPC may be connected to a primary PC (either in an expansion slot or in a drive bay) via a USB connection, for example, and be configured to run continuously and take over certain tasks from the primary PC as needed while the primary PC hibernates. The OPC may also be embedded in a monitor or other peripheral devices.
