Ray Tracing with the Single Slab Hierarchy
Bounding volume hierarchies have become a very popular way to speed up ray tracing. In this paper we present a novel traversal and approximation scheme for bounding volume hierarc...

The Permanent Requires Large Uniform Threshold Circuits
We show that thepermanent cannot be computed by uniform constantdepth threshold circuits of size Tn, for any function T such that for all k, Tk n = o2n. More generally, we show th...

Memory Hierarchy Design for a Multiprocessor Look-up Engine
We investigate the implementation of IP look-up for core routers using multiple microengines and a tailored memory hierarchy. The main architectural concerns are limiting the numb...
