Abstract:

Nowadays, most chip multiprocessor (CMP) designs face the challenge of how to keep the balance between on-chip parallelism, communication overhead, program performance, and resource utilization. By using the conception of physical core and logical processor, flexible-core CMPs(FCMPs) provide more optimization space. We propose a novel FCMP architecture named FTPA (flexible tiled processor architecture), which provides an efficient platform for single thread execution. The evaluation demonstrates that FTPA outperforms the state-of-art FCMP design, TFlex, by 19.2% on average.

Key words: flexible chip multiprocessors, logical core, physical core, dynamic resource tuning
