pipelining iir filters

Started by apchar 2 months ago54 views

Can someone recommend a readable source on pipelining recursive structures? There are many papers on IEEE on the Look-Ahead methods but they are all so very badly written they might as well be written in Klingon. And none talk about implementation. Is there a methodology that applies to the signal flow graph directly rather than just the transfer function? Not every filter can/should be broken down into biquads.

Thanks
