Depth of pipelining (Spartan 6)

[robiwan]

Hi all, I'm setting up a synth engine and I thought I'd pipeline it so I can get high voice count throughput, however, I'm estimating (very roughly) that I'll get somewhere between 30 to 50 pipeline stages. Is this "off the chart" when it comes to pipelining, or is it within reasonable bounds ? I'll be using an Atlys card for this.

It will depend on how wide your data path is, but there's no fundamental problem with that number of stages (though you might want to do some tests to see if it really makes much of a difference first)

 

[robiwan]

Well, I suppose the data path width would be quite wide, since there are a number of parameters and state variables that need to be propagated down to their correct pipeline stage. The design is still very conceptual (that is, only in my head), so alternative approaches/ideas are welcomed

Over 100 Stages is still OK! But the bottle neck is verification!!!!
