This is a curious article. When asked to prepare a review, there was no abstract, so the assignment was a bit open ended. The article seemed to be of interest; any analysis of hardware architectures from 1997 to 2011 should be interesting and provide insight into how the field has progressed. Alas, the article, while of interest, is mistitled. It should be "Analyzing worldwide distribution of hardware architecture technical papers, 1997-2011," since it could be characterized as an information retrieval (IR) exercise using keyword analysis of some 51,000 articles published in the interval. The techniques harken back to the early IR days of the late 1960s.
