1.1 i960
Features
The i960 RM/RN I/O processor serves as the main component of a high performance, PCI-based
intelligent I/O subsystem. The IQ80960RM and IQ80960RN platforms allow the developer to
connect PCI devices to the i960 RM/RN I/O processors using the four secondary PCI expansion
connectors. The features of the IQ80960RM and IQ80960RN platforms are enumerated below and
shown in
•
i960 RM/RN I/O processor
•
Modified PCI long-card form factor
•
64-bit or 32-bit primary PCI bus interface (80960RM 32-bit only)
•
64-bit or 32-bit secondary PCI bus connected to the primary PCI interface with a PCI-to-PCI
bridge (80960RM 32-bit only)
•
DMA channels on both PCI buses
• 2
I C Serial Bus
•
168-pin, 3.3V DIMM socket supporting 16 to 128 Mbytes of Synchronous DRAM organized
