Features

Speedup vs GPPs

Power requirements

Flexibility

Cost of the device

6

Speedup (vs GPP[*]

)

GPUs High speedup

ASICs Best possible

FPGAs High speedup

[*]

General Purpose Processor

7

Power requirements

GPUs High speedup Hundreds of watts

(Tesla K40 by Nvidia max 235W)

ASICs Highest possible Lowest possible

FPGAs High speedup Tens of watts

(Virtex7-VC707 by Xilinx abt 15W)

8

Flexibility

GPUs High speedup Hundreds of watts Programmable

ASICs Highest possible Lowest possible Application-specific

FPGAs High speedup Tens of watts Programmable

9

Costs

GPUs High speedup Hundreds of watts Programmable About 3000$ each

(Tesla K40 by Nvidia)

ASICs Highest possible Lowest possible Application-specific Too high if few

circuits required

FPGAs High speedup Tens of watts Programmable About 3500$ each

(Virtex7 VC707 by Xilinx)

MATRIX INVERSION

16

First case study

• Intense computation

• Useful in different applications(e.g. fluid dynamics lumped parameters model)

reusability

MATRIX INVERSION

First case study

So… FPGAs!

- High speedup vs GPPs

- Low power requirements

- Programmable

- Affordable costs
