Title:		EXPLORING THE CELL WITH HPEC CHALLENGE BENCHMARKS

ABSTRACT:

New architectures require thoughtful testing to explore the performance 
potential of the processor.  Here the HPEC Challenge Benchmarks are used 
to explore the Cell processor to understand the realistic performance as 
well as how that performance can be attained.  More specifically, for the 
time domain FIR benchmark, we find that a significant fraction (88%) of 
the peak performance can be achieved (as expected).  However, this 
performance does come at significant coding cost.
