A computing device that includes a host processor and a service processor is provided. The host processor is configured to interact with a first user interface. For example, the host processor may be a microprocessor for the device and the first user interface may be a display device. A service processor is provided and can interact with a second user interface. In some cases, the service processor may interact with the second user interface without communicating with the host processor. Accordingly, the service processor can perform functions without relying on the host processor. Using the service processor conserves processing power and also may allow the reduction in size of the device as the service processor may perform the functions previously performed by discrete hardware and the host processor.
