Abstract

Heterogeneous (or asymmetric) chip multiprocessors present unique opportunities for improving system throughput, reducing processor power, and mitigating Amdahl's law. On-chip heterogeneity allows the processor to better match execution resources to each application's needs and to address a wider spectrum of system loads-from low to high thread parallelism-with high efficiency.
