Full binary compatibility for PA-RISC
- Dynamic object code translator in HP-UX automatically converts PA-RISC code to native IA-64 code
- Translated code is preserved for later reuse
- Has passed the same tests as the PA-8500
- Close PA-RISC to IA-64 instruction mapping
- Translation on average takes 1-2% of the time Native instruction execution takes 98-99%
- Optimization done for wide instructions, predication, speculation, large register sets, etc.
- PA-RISC optimizations carry over to IA-64
