AFAIK, since 1991 (with the MIPS R4000) they have included the necessary interlocks in the integer pipeline. Just check the reference manuals from that age (e.g. compare the R3000 and R4000 manual section on the pipeline). Or else use a search engine to find sources like this: https://books.google.com.pe/books?id=LL52JBPU4CwC&pg=PA52 https://books.google.com.pe/books?id=LL52JBPU4CwC&pg=PA52 The article's author should review recent documentation on the MIPS architecture. I think that the paragraph that starts with the phrase "MIPS is the worst offender" seems ludicrous for people working with modern MIPS implementations (let's say post-1992!).
