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