Abstract
The invention relates to a method for downloading control software/operating systems of user interfaces into an electronic device (1), which comprises two or more processor blocks (2a, 2b), where in at least two processor blocks (2a, 2b) a user interface (UI1, UI2) is used. Furthermore, one or more operating systems are executed in the electronic device (1). The downloading is executed via one said processor block (2a, 2b), wherein the control software/operating systems are downloaded into said one processor block (2a, 2b), from which the control software/operating systems related to other user interfaces are loaded into said other processor blocks (2a, 2b). The invention also relates to an electronic device (1) which comprises at least one processor (3a, 3b), at least two processor blocks (2a, 2b), at least one user interface (UI1, UI2), memory means (4a) for storing the control software of the user interface (UI1, UI2), means (8a, 8b, 10) for data transmission between a first (2a) and a second processor block (2b), and means (3a, 3b) for executing the functions of two or more operating systems. The invention also relates to a storing means for the downloading program of the contr…
