It is the object of the invention to optimise the allocation of address ranges to modules of an integrated circuit. Since according to the invention the address ranges in the address space are selectable through a central address management, the usage of the address space capacity can be optimised according to the current load factor. Flexible usage of the address space is enabled by choosing the position of the address range to be selected and the size of the address range. The address range can be assigned automatically by a software program. The software program is for example designed in such a way that it executes a fair distribution of the address ranges to the existing modules or those modules that currently need an address range. Provided there are no overlaps with other address ranges, the address ranges to be assigned can be chosen as wished. User-specific programming can be used to allocate specific address ranges to individual modules.
