Intel® IQ80219 General Purpose PCI Processor Evaluation Platform
Introduction
The PCI Bus is an industry standard, high performance low latency system bus. The 80219 PCI Bus
is capable of 133 MHz operation in PCI-X mode as defined by the PCI-X Addendum to the PCI Local
Bus Specification, Revision 1.0a. Also, the processor supports a 66 MHz conventional PCI mode as
defined by the PCI Local Bus Specification, Revision 2.2. The addition of the Intel XScale
®
core
brings intelligence to the PCI bus application bridge.
The 80219 is a single function PCI device. This function represents the address translation unit. The
address translation unit is an “application bridge” as defined by the PCI-X Addendum to the PCI
Local Bus Specification, Revision 1.0a. The 80219 contains PCI configuration space accessible
through the PCI bus.
80219 core is based upon the Intel XScale
®
core. The core processor operates at a maximum
frequency of 600 MHz. The instruction cache is 32 Kbytes (KB) in size and is 32-way set associative.
Also, the core processor includes a data cache that is 32 KB and is 32-way set associative and a mini
data cache that is 2 KB and is 2-way set associative.
The 80219 includes eight General Purpose I/O (GPIO) pins.
