IBM3206K0424
IBM Processor for Network Resources
Preliminary
External Architecture
The IBM Processor for Network Resources has four major interfaces:
A System Bus which acts as an actively cached memory slave and as a master for the PCI 32-bit bus.
The Physical (PHY) Interface which supports several physical layer hardware devices that perform parallel
to serial data conversion and the rest of the transmission convergence.
An External DRAM Interface that controls one or two arrays of two-bank interleaved DRAM with 60 ns
access time for Packet and Control Memory. The interface is direct drive to the DRAM.
The Control and Configuration Interface which covers a number of functions. It gives access from the sys-
tem bus to the PHYs and to EPROM. The EPROM can also be used to hold initial device configuration, up to
and including PVC configurations.
Note: IBM3206K0424 has built-in, self-test logic.
The four major interfaces allow the IBM Processor for Network Resources to be used in both "deep" and
"shallow" adaptors with minimal external logic. (See Block Diagrams of Possible Systems on page 33 for
examples.)
