Heyho,
Hi, Steffen.
During the 1980's, I commissioned a 9216 processor CLIP4R (Cellular
Logic Image Processor) SIMD array built for the MRC by the Rutherford
Appleton labs. This used FPGA's and custom LSI processors to run IPC,
which was a customised version of C for image processing (not
Inter-Process Communication).
I spent three years learning to program this machine in the CLIP4R
assembly language and IPC. I also worked with my colleagues on
alternative loosely-coupled 680x0-based VME systems that we compared
with the CLIP4R processor array. We concluded that it was not worth the
huge effort of using such highly specialised systems that only a few
people in the world, including me, knew how to program.
I know that things have moved on since then, but the principle remains
the same. Unless there are many people using the same technology, the
task of developing for it is extremely difficult. That said, using FPU's
for SIMD not to mention the GPU's has come into the mainstream.
My experience was that the (huge) performance advantage of the CLIP4R
system was overwhelmed by the difficulty of actually using it to do a
job analysing images of metaphase chromosomes...
I would stick to using GPU's and CUDA/OpenCL if you want to improve the
performance of your bioinformatics applications.
Bye,
Tony.

This is some nice development!
:) development this means, indeed!
That said, there are some other companies that has tried this out and I
doubt this will really take off.
Well, I do not see any FPGA company that has collaborated with the
Open Source community so much, yet ... well, indeed, there is one
in Sweden behind OpenRisc [1,2], but application acceleration is yet
