High-performance out-of-order processors spend a significant portion of their execution time on the incorrect program path even though they employ aggressive branch prediction al...

Fetch gating mechanisms have been proposed to gate the processor pipeline to reduce the wasted energy consumption due to wrongpath (i.e. mis-speculated) instructions. These scheme...

For many applications, branch mispredictions and cache misses limit a processor’s performance to a level well below its peak instruction throughput. A small fraction of static i...
This paper evaluates performance characteristics of the Compaq ES40 shared memory multiprocessor. The ES40 system contains up to four Alpha 21264 CPU’s together with a high-perf...
