In the original processor, distance values that lie between a lower value min and an upper value max are permissible for the base register-relative addressing. The supported address space on the original processor for the code to be emulated is limited in such a manner that the conversion of address operands as described in the following steps leads to semantically equivalent behavior on the target processor.
