vlsi architecture survey

1.VLSI Architecures: Past, Present and Future
For fine-grain machines to bcome reality one has to overcome obstacles in 3 areas:
a. Managing Locality.(for real programs with irregular,data-dependent,time
-varying data
staructures. )
b. Reducing Overhead(communication, synchronization etc)
c. smooth transition (see below)
"One approach to migration is to use Smart Memories chip as memory for a conventional
processor" -William J Dally.
HW/SW mechanisms are required to manage the placement and migration of data to minimize
use of scarce off-chip bandwidth and avoiding long on-chip latencies.
