IBM3206K0424
IBM Processor for Network Resources
Functional Description
The IBM3206K0424 has been designed by breaking the implementation of the various functions and data-
flows into separate entities (major functional units).
This processor acts as a conversion unit from a bus memory interface (which is Work Queue oriented) to a
PHY level ATM. To accomplish this, the IBM3206K0424 contains the major functional units listed below and
shown in the Dataflow on page 27.
