System Configurations

networking systems. In solutions requiring data searching such as

routers, a system configuration as shown in Figure 1.0 may be realized.

Maximum flexibility is provided by allowing one board design to be

populated today using either the IDT 75P42100 or 75P52100 NSEs and

later upgraded to use the IDT 75K62100 NSE. Applications note AN-279

discusses how to accommodate one board design for any of these NSEs.

ASIC/ FPGA for lookups and routes an Index to an associated SRAM

device, which supplies the next hop address via an SRAM Data Bus to

the ASIC. The NSE provides the required control signals to directly

hookup to ZBT™ or Synchronous Pipeline Burst SRAM. Lookup results

can also be fed directly back to the ASIC/ FPGA without the use of external

SRAM. Control of the associated handshake signals is provided by all

NSEs to adapt to either configuration.

Device Description

(NSEs) and a comprehensive suite of software that enable and accelerate

the intelligent processing of network services in communications equip-

ment. As a part of the complete IDT classification subsystem that includes

content inspection engines, the IDT family of NSEs delivers high-

performance, feature-rich, easy-to-use, integrated search accelerators.

synchronous full-ternary 128K x 72 entry device. Each entry location in

the NSE has both a Data entry and an associated Mask entry. The NSE

devices integrate content addressable memory (CAM) technology with

high-performance logic. They can perform Lookup and Learn NSE

operations plus Read, Write, Burst Write, and Dual Write maintenance

operations.

multiplexed address and data bus that can support 100 million sustained

searches per second. This device provides array segments which can

be configured to enable multiple width lookups from 36 to 576 bits wide.

The IDT 75K62100 requires a 1.2-volt V

supply. This NSE device provides the user with flexibility and control in

determining the device power. Only the array segments that will be used

for a specific NSE operation are powered up while the unused segments

are not.

processing technology and is packaged in a JEDEC Standard, thermally

enhanced, low profile Ball Grid Array. The IDT 372 BGA package

provides increased heat transfer for thermally challenged systems. The

372 BGA footprint is backwards compatible with the IDT 64K x 72 Entry

(75P52100) and 32K x 72 Entry (75P42100) NSE devices.
