Summary: | In this paper, an algorithm named MuVoF is proposed to perform
multivoltage multifrequency low-energy high-level synthesis for functionally
pipelined datapath under resource and throughput constraints. A
datapath is partitioned into a number of pipelined stages such that the clock
period can be extended maximally. A multivoltage assignment algorithm
then utilizes the extended clock period to reduce energy by lowering the
supply voltages of the resources. The results are further refined by four
local transformations performed in an iterative process. The experiment
results show that MuVoF is capable of exploring the design space effectively
and achieves efficient energy reduction. |
