Chapter 4. Itanium Instruction Formats and Addressing
The designers of any new computer architecture face many decisions. Their general approaches and their choices of details affect not only the potential success of the first implementation, but also the evolutionary possibilities for all future models. The successes and shortcomings of earlier architectures from all manufacturers provide lessons that design teams dare not forget, as influential critics will inevitably draw such comparisons. Research on new architectural principles may also provide novel and worthwhile ideas for new implementations over the life span of an architecture.
The Itanium architecture and its Explicitly Parallel Instruction Computing (EPIC) principles set a new direction ...
