NLA88650 Knowledge-Based Processors

Currently Viewing:

The NL88650 Knowledge-Based Processor (KBP) performs high-speed operations on large rule databases for a wide range of telecommunications applications, including 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 needs through high-performance, parallel decisions and improved entry storage capabilities. Up to four parallel operations allow the device to reach several Billion Decisions Per Second (BDPS).  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. 
 
This KBP seamlessly connects to the Arad BCM88650.
