Cypress Semiconductor Corporation’s (Cypress’s) network
database coprocessor (NDC) performs the following three
primary functions.
There are two ways to build the NDC system.
The NDC runs up to 100 MHz. At that speed and running with
a 64-bit bus interface, the NDC performs at a peak rate of 33

device acts as a bridge between network processor(s) and
a search subsystem of Cypress’s CYNSE70XXX network
search engines (NSEs) plus optional associated SSRAMs
that contain a search database and the associated data for
a variety of network protocol layers. The CYNCP80192
device interfaces to the network processor with an SSRAM
interface and offloads the search function to provide support
for fast packet processing in routers and switches.

throughput. The CYNCP80192 device manages the
pipeline for optimal search performance and packs
instructions back to back in order to avoid any bubbles in

“NDC Subsystem Power-up Initialization Procedure” on
page 19), and the CYNCP80192 device returns the
associated data in response to a search operation. This type
of implementation is suited to applications where the
associative data size is up to eight bytes.
index of the successful search entry to the network
processor. The network processor uses this index to access
SSRAMs in order to get the required results. The SSRAMs
containing the associative data are connected directly to the
network processor’s SSRAM bus. This is suitable for
applications where the associative data size is longer than
eight bytes.
Overview
million searches per second on 68-bit entries, 25 million
searches per second on 136-bit entries, and 16.67 million
searches per second on 272-bit entries. At 100-MHz speed
and running with a 32-bit bus interface, the NDC performs at
a peak rate of 25 million searches per second on 68-bit entries,
16.67 million searches per second on 136-bit entries, and 10
million searches per second on 272-bit entries.
The NDC supports centralized, multiple layer, multiwidth
tables in order to provide cost effective search solutions for
Ethernet, asynchronous transfer mode (ATM), and Sonet-
based switches and routing systems. It supports the following
advanced capabilities: quality of service (QoS), class of
service (CoS), virtual private network (VPN), packet and flow
classification, and security.
