1. A data-processing arrangement comprising: a main processor that has been provided with a system-program code that causes the main processor to write an application-program code into a shared memory, and that causes the main processor to write an address indication, which indicates where the application-program code has been written into the shared memory, into a predefined memory location; an auxiliary processor that has been provided with a startup-program code that causes the auxiliary processor to retrieve the address indication from the predefined memory location so as to subsequently transfer the application-program code from the shared memory to an application-program memory that belongs to the auxiliary processor.
