Not at all. The NS32016 displacements cover its entire adddress-space (24 bits, 16Mbyte). The more recent Series 32000 processors (such as the NS32532), have a 4 GIGA-byte address-space. You can use a displacement to reach out to as much as one Giga-byte. Register-relative addressing modes can be used to span the entire 4 Gbyte range.
