Abstract
A storage device (3), such as an SD card, that is coupled to a host device (2), such as a mobile phone, includes a computing environment (8). The computing environment (8) includes an application processing part (6), and a separate interface processing part (7). The application processing part (6) of the computing environment 8 is operable to execute one or more applications on the storage device (3). The interface processing part (7) of the computing environment 8 includes an interface processor that interfaces between a communications protocol used between the host device (2) and the storage device (3), and a communications protocol used by the application processor in the application processing part (6) of the storage device (3). The interface processor communicates with the application processor via interrupts and a shared memory (9).
