This is an 'odd-ball talk' that takes a brief tour of the architecture enhancements to the popular 808x series of processors over the past 20 years to arrive at their pièce de résistance - The Itanium. In contrast a backwards look is taken to the time when IBM made it's monumental break-though in the 1960s by releasing it's first System/360 series of upgradeable processors. Itanuim and S/360 share some remarkable facets of their architecture and in consequence they also share technological challenges.

This is a talk for the programmer or engineer, who understands the principles of programming and has a conceptual view of how high-level languages are translated to byte-codes, which are acted on by the hardware. Just how processors act on byte codes, at least in the case of the S/360 and its successors, may come as a surprise as the covers are lifted on a most remarkable and elegant aspect of computer processor engineering.

Richard Moore is a Senior Consulting IT Specialist and engineer at IBM. He has worked on many different processor architectures and operating systems in is 28-year career in IT. Since 2000, Richard has worked in IBM's Linux technology Centre both as a lead developer for Linux kernel diagnostic tools and an engineering consultant. He was responsible for bringing kprobes to Linux and now working on real-time Linux systems.
