IA-64 : Next Generation Architecture
EPIC : explicit parallelism, predication, speculation
Register Model : large register file, rotating registers, register stack engine
Floating Point and Multimedia Architecture : 128 registers, parallel arithmetic, extended precision calculations, FMAC
Memory Management : 64-bit addressing, memory hierarchy control
Compatibility : IA-32 instructions in hardware, PA-RISC through software translation
Execute more instructions in the same amount of time
Optimized for object oriented applications (C++, Java)
High performance 3D, compression and array operations
Large memory support, efficiently manages data flow to / from memory
Existing software runs without recompiling
- World-class performance for E-services applications
- More complex scientific / financial analysis and faster image rendering
- Higher throughput of rich Internet content
- Increased system scalability for large applications
- Preserves investment in existing software
