Abstract
According to one aspect, a multifunctional computing device having a wireless communications processor (e.g., cellular processor) and an application processor (e.g., general-purpose processor such as a CPU) share a storage device that is associated with or attached to the application processor. An example of such a multifunctional computing device may be a Smartphone device having a cellular phone and handheld computer functionalities. There is no specific storage device directly associated with or attached to the wireless communications processor (hereinafter simply referred to as a wireless processor). Instead, the wireless processor communicates with the application processor via a high speed communications link, such as a USB link, to access code and data stored in the storage device (e.g., flash memory device) associated with the application processor.
