Comparisons

ADRES vs. MorphoSys

• Why we do this?
  • They are among the most recent RC architectures and seem to be popular (many citations).
  • To get the most programmable reconfigurable architecture.
• Comparison

  	ADRES	MorphoSys
  1st publ.	Mei et al. 2003	Singh et al. 1999
  Granularity	coarse	coarse
  Type of coupling	Tightly coupled	Loosely copuled

  • MorphoSys has a loosely copuled accelerator leading to:
    • complicated programming for explicit data-passing interface at design time.
    • significant data-passing overhead at runtime.
  • ADRES is more programmable, MorphoSys is more restricted ( need more details).
