• It is shown that only a 7% of 300mm^2 die can be used at full frequency within a power budget of 80W. The un-utilized part of the chip is now-a-days called Dark Silicon. The dark silicon can be replaced with accelerators as they are not used most of the time.
• Another motivation to propose an accelerator-rich platform is to meet an increasing demand for throughput, for example the number of spatial streams in IEEE-802.11x family of wireless standard has increased from one to eight.
