Patent ID: 7062632

Claim:
A method for controlling a central processing unit for addressing in relation to a memory, wherein a set of operation code identifiers including at least one special operation code identifier is associated to the central processing unit, wherein the central processing unit is arranged to address a first memory area having a first memory size of the memory, wherein the method comprises the following steps: monitoring a data traffic from the memory to the central processing unit by supporting means coupled to the central processing unit; in the case in which the data traffic from the memory to the central processing unit includes the special operation code identifier, forming a new address by the supporting means, wherein the new address is defined in a second memory area having a second memory size of the memory, wherein the second memory size is larger than the first memory size; providing a predetermined operation code identifier to which a jump command from a conimand set of the central processing unit is assigned, to the central processing unit by the supporting means, wherein the predetermined operation code identifier has a destination address in relation to the first memory area; and managing a code descriptor by the supporting means, yielding, together with the destination address, the new address.
