Abstract:
The SPARC platform has existed for over 25 years, with continued binary compatibility. The latest of these processors, the SPARC T5, is about to be released. Oracle published a short written interview with the Rick Hetherington, who is leading the charge on newer SPARC processors.

SPARC T5 Deep Dive:
Oracle regularly publishes short question-answer articles, called Deep Dives, regarding new platforms during the release phase. This latest SPARC T5 release is no different. An overview and questions are listed below. This is the article, for the answer to the questions.
Rick Hetherington, Oracle’s vice president of hardware development, manages a team of architects and performance analysts who design Oracle’s M- and T-series processors. In this interview, Hetherington describes the technical details of the new SPARC T5 processor and expands on the process that is used to design these innovative chips.
