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
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.
