DSP inside FPGA
I know some thing,
if you want to implement a good, optimum DSP circuit on a FPGA, you should know both of them very well. I have not used sysGen yet, but I have had some big DSP designs on FPGA, and I'm sure that, Some one with the experience of designing hardware for TI or Analog devices's DSPs , is not equal to a person who does not have such an experience. I mean, if you want to really get succeed you should know, bot of them very well, whatever tool you use for your work.
