Intel® IQ80321 I/O Processor Evaluation Platform

Introduction

It is an integrated processor that addresses the needs of intelligent I/O applications and helps reduce intelligent I/O system costs.

The PCI Bus is an industry standard, high performance low latency system bus. The 80321 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 80321 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 80321 contains PCI configuration space accessible through the PCI bus.

80321 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 80321 includes eight General Purpose I/O (GPIO) pins.
