In this paper we present a retrospective on our paper published in ICS 1995, which to best of our knowledge was the first paper that introduced the concept of a cache memory with multiple subcaches, each tuned for a different type of locality. In this retrospective, we summarize the main ideas of the original paper and outline some of the later work that exploited similar ideas and could have been influenced by our original paper, including two actual industrial microprocessors.
