Intel® 80321 Software Conversion to Intel® 80332 I/O Processor Application Note
The Intel® 80332 I/O processor (80332) is the first PCI Express* I/O
processor in the Intel XScale® microarchitecture family of I/O
processors. The 80332 integrates two PCI Express*-to-PCI-X bridges with
Intel® 80321 I/O processor (80321) peripherals that have improved
performance for next-generation products. The improvements over the
80321 provided in the 80332 include improved memory-controller
architecture, higher-speed memory and internal busses, and a
higher-performance interrupt controller. This application note describes
these changes and the impact of converting a 80321 software stack to the
80332.Intel is a trademark or registered trademark of Intel Corporation or its subsidiaries in the United States and other countries. ARM* and StrongARM* are registered trademarks of ARM, Ltd. Other names and brands may be claimed as the property of others.
