Tony, While I wasn't there (the dinner) I do believe that AMD has kept it short and sweet (as you put it) between the latches. Steve PS. It looks liek June 14th has surfaced as a date again.. (www.aceshardware.com). I'm not sure what AMD is doing right now.

Tony, I thought you said the K7 was all by-hand laid out. Wasn't that at least partially for speed optimization purposes? I think it was done exclusively for speed optimization. My comments about speed work were based on the fact that it is a very immature design, and that Dirk said they hadn't pushed the clock speed very hard. Once they get on the e-beam, they will be able to start knocking the real speedpaths down quickly. Did Meyer talk about design rules for the K7, like rule of thumb maximum number of logic levels between latches, or clocks? You have always been impressed by the deepness of the pipeline in the K7, did they also keep it "short and sweet" between the latches? Good question. Dirk said that they went to great lengths to make sure the pipeline was evenly partitioned. Without the 3-cycle L1, even a 20 stage pipeline would be useless for improving MHz. Scumbria

Tony Viola, <You have always been impressed by the deepness of the pipeline in the K7, did they also keep it "short and sweet" between the latches?> Such a remark from a seasoned "professional" like you should not be tolerated, and I am very sad that all my efforts to educate you (and mostly Ph.D Yousef) have failed to significant extent. The answer to your question is: "The sole reason for deep pipelines is to keep it "short and sweet" between the latches!" But you are doing a good progress though. "short and sweet between latches" is a good concise description of the issue. Congratulations.
