Features
The 80331 combines the Intel XScale
processor. This multi-device I/O Processor is fully compliant with the PCI Local Bus Specification,
Revision 2.3 and the PCI-to-PCI Bridge Architecture Specification, Revision 1.1. The
80331-specific features include:
The subsections that follow briefly overview each feature. Refer to the Intel
Developer’s Manual for full technical descriptions.
Intel XScale
The 80331 is based upon the Intel XScale
frequency of 800 MHz. The instruction cache is 32 Kbytes in size and is 32-way set associative.
Also, the core processor includes a data cache that is 32 Kbytes and is 32-way set associative, and
a mini data cache that is 2 Kbytes and is two-way set associative.
PCI-to-PCI Bridge Unit
The 80331 provides a PCI-X to PCI-X Bridge unit. The bridge Primary and Secondary PCI-X
support 64-bit 133 MHz interfaces compliant to the PCI-X Addendum to the PCI Local Bus
Specification, Revision 1.0a.
