What is your basis for the claim they&#x27;ve not evaluated the tradeoffs or tried to design an efficient implementation?<p>The patent seems to be based on this paper: <a href="http:&#x2F;&#x2F;dl.acm.org&#x2F;citation.cfm?id=264189" rel="nofollow">http:&#x2F;&#x2F;dl.acm.org&#x2F;citation.cfm?id=264189</a>. It has an extensive experimental evaluation. Another thing to keep in mind is that Sohi, Vijaykumar and Moshovos are all respected computer architecture researchers, and this paper was published in ISCA, which is <i>the</i> best and most competitive forum for computer architecture research.
