3.0
3.1
The CFG registers contain information for configuring the
CYNPC80192. These registers also include error, status,
mask, and information registers.
3.2
This logic block contains the random access registers through
which the network processor(s) perform most of the table
programming, management functions, and search operations
(via a request-response protocol). A network processor posts
operation requests and Reads responses back from this
access block.
3.3
Protocol Conversion Logic
This unit uses pipeline management logic to optimize the
search performance through the NSE pipeline. This unit posts

the commands to the NSE and steers the results to the
appropriate locations in the operating registers. It also
converts the SSRAM interface information from a network
processor into protocol cycles of the NSE transactions. This
unit builds on the commands provided by the NSE to provide
more advanced table management commands to the network
processor.
3.4
This interface generates the appropriate hardware handshake
with the NSE(s). This block is a slave to the pipeline control
unit and drives the NSE(s) bus with the appropriate
commands.
3.5
The data transfer between the SSRAM and the pipeline unit
takes place in this interface. The pipeline unit further transfers
this information to the operating registers.
