BCM52311 Datasheet | Broadcom

Description Features The BCM52311 Knowledge-Based Processor (KBP) performs high-speed operations on large-rule databases for a wide range of telemunications applications, including WAN, MAN, and Enterprise switches and routers. It provides network awareness and enables real-time modifications and updates to the routing configuration, making it ideal for packet classification, policy enforcement, and forwarding. This family of KBPs addresses next-generation classification requirements through high-performance parallel decisions and improved-entry storage capabilities. Up to eight parallel operations allow the device to reach decision speeds of multiple billion decisions per second (BDPS). Embedded error correction circuitry (ECC) improves system testability and operational reliability. The key processing unit (KPU) enables efficient interface transfers with flexible search key construction. This KBP seamlessly connects to the Jericho BCM88670, Arad Plus BCM88660, and Arad BCM88650. - Dual host enables two host devices to connect to one KBP. - Connectivity provided to NPUs that can produce search keys through two independent ports. - Device available in 2048k/1024k/512k 40b database entries. - KBP tables are width configurable to 80/160/320/480/640 bits. - User data array for associated data, width configurable as 32/64/128/256 bits. - Up to eight parallel searches enabling up to eight results per operation. - Simultaneous multithreading (SMT) operation. - Net Route forwarding solution for longest prefix match (LPM). - Net ACL solution for access control list. - Logical tables provide support for intelligent database management. - Key processing unit (KPU) for flexible search key construction. - Result buffer provides programmability for flexible routing of search results. - Range matching for efficient storage utilization. - ECC on user data and database array. Parity protection on all embedded memories. - Background ECC scan for database entries with provision for...
