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 control software/operating systems of the user interfaces in an electronic device (1).

Claims

1. 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, and in the electronic device (1) one or more operating systems are also executed, characterized in that the downloading is executed via one said processor block (2a, 2b), wherein the control software/operating systems of the user interfaces are loaded 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).

2. The method according to claim 1, characterized in that the control software/operating systems of the user interfaces (UI1, UI2) are downloaded from a memory card (12), such as a multimedia memory card (MMMC).

3. The method according to claim 1, characterized in that the operating systems are downloaded from a data processor (13).
