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.
