M7010R

DESCRIPTION

Overview

The M7010R is a feature-rich, TCAM-based hard-

ware search engine optimized for networking and

communications applications. It incorporates lead-

ing-edge Associative Processing Technology

(APT, trademark of Cypress Semiconductor, Inc.)

and Advanced Power Management. The data ta-

ble may be partitioned into up to four (4) quad-

rants, allowing the user to configure each quadrant

with different table entry widths (x34, x68, x136, or

x272-bit). It is also programmable to accelerate

performance.

Performance

The M7010R outperforms competitive solutions

using software sequential search algorithms in

conjunction with SRAMs or ASICs, or hardware

implementation with ASICs and CAMs. The latter

solution, while faster than a software-based solu-

tion, still suffers from performance degradation

when depth-cascaded and is unable to scale to

next-generation requirements. The M7010R-

based solutions overcome all of these drawbacks.

Applications

The performance and features of the M7010R

makes it ideal in applications such as enterprise

LAN switches, broadband switching and routing

equipment, supporting multiple data rates from

OC–48 and beyond.

Figure 2 illustrates how a search engine sub-

system can be optimized using a host bridge

ASIC, the M7010R, and synchronous or non-syn-

chronous SRAMs. It also illustrates how this sys-

tem fits into a switch-router implementation.
