Functional Overview
As indicated in
an intelligent I/O processor. Subsections following the figure briefly describe the main
features; for detailed functional descriptions, refer to the Intel
User’s Guide (272736).
The PCI bus is an industry standard, high performance, low latency system bus that
operates up to 132 Mbyte/s. The 80960RX, a multi-function PCI device, is fully compliant
with the PCI Local Bus Specification, Revision 2.1. Function 0 is the PCI-to-PCI bridge
unit; Function 1 is the address translation unit.
The PCI-to-PCI bridge unit is the connection path between two independent 32-bit PCI
buses and provides the ability to overcome PCI electrical load limits. The addition of the
Intel
The 80960RX, object code compatible with the Intel
sustained execution at the rate of one instruction per clock.
The local bus, a 32-bit multiplexed burst bus, is a high-speed interface to system memory
and I/O. A full complement of control signals simplifies the connection of the 80960RX to
external components. Physical and logical memory attributes are programmed via
memory-mapped control registers (MMRs), an extension not found on the Intel
(80960KX), Intel
and logical configuration registers enable the processor to operate with all combinations
of bus width and data object alignment.
