IQ80960RM/RN Evaluation Board Manual 1-1
Introduction 1
This manual describes the IQ80960RM and IQ80960RN evaluation platforms for Intel’s i960
®
RM/RN I/O processor. The i960 RM/RN I/O processors combine an 80960JT core with two PCI
bus interfaces, as well as a memory controller, DMA channels, an interrupt controller interface, and
an I
2 C serial bus. The difference between the two processors is that the 80960RN utilizes 64-bit
primary PCI and secondary PCI buses while the 80960RM utilizes both a 32-bit primary and
secondary PCI bus. The IQ80960RM and IQ80960RN platforms are full-length PCI adapter boards
and are 8.9” in height to accommodate four standard PCI connectors on the secondary PCI bus.
The boards can be installed in any PCI host system that complies with the PCI Local Bus
Specification Revision 2.1. PCI devices can be connected to the secondary bus to build powerful
intelligent I/O subsystems.
