"I was an FPGA engineer before and I think high performance computing
based FPGA will lead to a bright future. However through my recently
projects I found GPU will be more appropriate when there is a
acceleration need.
In embedded system, FPGA co-processing plan:
Intel E6x5C
and GPU co-processing plan:
AMD APU (with opencl support)
and in desktop system, FPGA co-processing plan:
Full custom design, mostly will be based on PCIe fabric
and GPU co-processing plan:
nVidia CUDA (with opencv basically support)
If I choose FPGA co-processing, the algorithm will be specifically
optimized and R&D time will be very noticeable. If I choose GPU plan,
algorithm migration will cost little time(even the original one is
Matlab code), and the acceleration performance will also be quite
well.
As a conclusion, the FPGA acceleration only suits some certain and
fixed application. However in the real world , many projects and many
algorithms are very uncertain and arbitrary. With same power
consumption, GPU plan may lead better results. For a concrete
project, I will consider GPU or DSP, and FPGA at last.
Do everybody agree? "
so comment on it........
