DESCRIPTION:With the shorter time-to-market and the rising cost in SoC dev
 elopment\, the demand for post-silicon programmability has been increasing
 . Recently\, programmable accelerators have attracted more attention as an
  enabling solution for post-silicon engineering change. However\, programm
 able accelerators suffers from 5∼10X less energy efficiency than fixed-f
 unction accelerators mainly due to their extensive use of memories. This p
 aper proposes a highly energy-efficient accelerator which enables post-sil
 icon engineering change by a control patching mechanism. Then\, we propose
  a patch compilation method from a given pair of an original design and a 
 modified design. Experimental results demonstrate that the proposed accele
 rators offer high energy efficiency competitive to fixed-function accelera
 tors and can achieve about 5X higher efficiency than the existing programm
 able accelerators.
