Now youre talking.
Taking ladspa and mapping it to FPGA: how? and how
would you do this
efficiently, if you could do it? A C function to VHDL function
convertor? (it's been a long time since I've worked with FPGAs. I'm sure
there are advances)
Yeah, there are C to VHDL compilers, but I think there a bit wierd. I'm
not sure they'd give you floating point operations.
Another route would be to weld a lowend cpu on the board, but I'd guess
that will be expensive and difficult.
It might be more cost effective to use DSPs -- that
is: more cost
effective in the long run for everybody -- mostly the end user.
Yes, but coding for DSPs is really hard work, and LADSPA plugins wont port
over as they use floating point maths.
