TCAM and BCAM Compilers

TCAMs and BCAMs: Ternary and Binary Content-Addressable Memory Compilers

eSilicon embedded binary and ternary content addressable memories (BCAMs and TCAMs) have been provided to networking customers for over 10 years, helping these customers meet the demand for wire-speed packet processing, access control lists and other requirements of high-bandwidth delivery. eSilicon binary and ternary CAMs are available in geometries from 14nm/16nm to 180nm.

Process Status
16nm FF+ Available
28nm HPM In production
40nm LP In production
40nm G In production
55nm LP In production
65nm GP In production

High-Performance, High-Density Embedded CAM Compilers for Network Applications

eSilicon offers a broad range of feature-rich, high-performance, high-density eFlex™ embedded CAM compilers. Our eFlexCAM™ compilers provide high-efficiency, cost-effective solutions for applications such as network search engines, cache for network processors, QoS services, classifications, Ethernet, ATM switches and other diverse networking applications.

User-Selectable Features

In addition to a full set of standard features, our eFlexCAM compilers provide a comprehensive set of user-selectable features that are chosen at compile time. Customers can choose just the features that they need for a specific application to optimize performance, power or area (PPA).

eSilicon’s philosophy for developing TCAMs is to customize the CAMs to end-customer requirements. This usually involves building custom logic and turning on multiple knobs to fine-tune the performance, power or area to customer application requirements. The chart below shows some of the elements that eSilicon has successfully used in the past to meet customer targets.
