BCM15K

16nm Heterogeneous Knowledge-Based Processors (KBPs)

Currently Viewing:

The Broadcom BCM15000 (BCM15K) is a series of 16nm knowledge-based processors (KBPs) that perform high-speed operations on large-rule databases for a wide range of telecommunications applications, including data center and enterprise networking 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 needs through high-performance parallel decisions and improved entry storage capabilities. Up to eight parallel operations allow the device to reach decision speeds of 7.2 billion searches per second (BSPS). Embedded error correction circuitry (ECC) improves system testability and operational reliability. The key processing unit (KPU) and the context buffer (CB) enable efficient interface transfers with flexible search key construction.
