Why FAWN ?

  • I/O bottlenecks cause low CPU utilization.

  • Modern processors spend a lot of energy in special features (Branch prediction, speculative execution, and increasing the amount of on-chip caching).

  • Dynamic power scaling on traditional systems is ineffective.

CPUS performance and energy-efficiency.

FAWN: faster I/O (flash) and simpler/slower CPU:

  • Resource utilization (no I/O bottlenecks).

  • Low power (simpler cpu, flash).
