IA-64

Microprocessors continue on the relentless path to provide more performance. Every new innovation in computing—distributed computing on the Internet, data mining, Java programming, and multimedia data streams—requires more cycles and computing power. Even traditional applications such as databases and numerically intensive codes present increasing problem sizes that drive demand for higher performance. Design innovations, compiler technology, manufacturing process improvements, and integrated circuit advances have been driving exponential performance increases in microprocessors.

To continue this growth in the future, Hewlett-Packard and Intel architects examined barriers in contemporary designs and found that instruction-level parallelism (ILP) can be exploited for further performance increases.

This project examines the motivation, architecture, and benefits of the major features of IA-64.
