Abstract
The present invention discloses a portable computing device () including a processor (), non-volatile memory (), and a volatile memory (). An execute in place (XIP) kernel () stored in the non-volatile memory is executed immediately upon powering up the device. As the XIP kernel is executed, the processor maintain state and context information () in the volatile memory. The XIP kernel includes user interface and application segments, allow the user to perform some functions immediately upon powering up the device. While executing the XIP kernel and full code instantiation () is loaded into the volatile memory. The full code instantiation includes identical code as is in the XIP kernel, in addition to other code. Once loaded, execution is switched () from the XIP kernel to the full code instantiation, providing full functionality of the device.
