The storage and processing of persistent objects presents opportunitie
s for add-on hardware support. Particularly, there are aspects of memo
ry management and whole-structure processing which are seen to benefit
from a novel kind of SIMD-parallel architecture. This paper discusses
the top-down requirements for handling persistent objects and then de
scribes an active memory unit called the IFS/2 which meets these requi
rements. Performance figures for prototype hardware are given, and its
application to an object-oriented data model is briefly described.
