eSilicon embedded binary and ternary content addressable memories (BCAMs and TCAMs) have been provided to networking customers for over 15 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 7nm to 180nm.
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.
In addition to a full set of standard features, our eFlexCAM TCAM and BCAM 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.
