Silent Large Datapath (SLD) is a low power reconfigurable accelerator for high performance embedded
systems. By using a large PE (Processing Element) array consisting of pure combinatorial circuits, the overhead
for clock distribution and storing/reading intermediate results to/from registers can be omitted. A small microcontroller
manages distribution and collection of data between PE array and data memory module for flexible data
allocation to the fixed datapath on the PE array. Dynamic voltage scaling is applied for the whole PE array and
the energy of the PE array can be saved by using the slack time of the datapath. Compared with corresponding
pipelined accelerator, SLD can achieve 29% improvement of energy efficiency. |
