Several manufacturers have recently announced the first simultaneous-multithreaded processors, both as single CPUs and as components of multi-CPU chips. All are small scale, compr...
Abstract—Resizable caches can trade-off capacity for access speed to dynamically match the needs of the workload. In Simultaneous Multi-Threaded (SMT) cores, the caching needs ca...
The register file is one of the most critical datapath components limiting the number of threads that can be supported on a Simultaneous Multithreading (SMT) processor. To allow t...
In this paper, we propose Runahead Threads (RaT) as a valuable solution for both reducing resource contention and exploiting memory-level parallelism in Simultaneous Multithreaded...
Simultaneous Multithreaded (SMT) processors improve the instruction throughput by allowing fetching and running instructions from several threads simultaneously at a single cycle....
