Re: System Generator vs Synplify DSP vs Simulink HDL Coder

SysGen can be used with Synplify. The HDL it creates is highly
structural so the choice of the synthesizer is not as important as it
might be when writing more behavioral HDL. I think the most problematic
part of image processing designs is the memory interface. Designing a
convolver, for instance, is much easier than figuring out how to keep
the convolver fed with data from the image RAM. I'd keep this foremost
in mind when selecting a design flow. -Kevin

Thanks for the response. I agree, the image processing bits are
usually fairly simple. Do you think System Generator is high-level
enough for an algorithm guy to use competently or does it still
require a fair amount of FPGA knowledge. (I'm an FPGA/VHDL guy btw)
The algorithm guys would love to be able to come up with their
algorithm and just run it on the hardware without us FPGA guys at
all.

I'm not necessarily saying the image processing is simple; it's just not going to be where you spend most of your design time, especially if external memory is involved.

You can use SysGen and, probably to a greater extent, AccelDSP, without hardware knowledge. But, as with most high-level design tools, having hardware knowledge is necessary to achieve the optimally fastest/smallest implementation.
