BCM53003B0KPB is a single-chip network processor developed by Broadcom Corporation, an American IC company. It has a powerful network processor, advanced hardware acceleration engine and flexible network programming instruction set. It is mainly used in mid-and high-end broadband applications such as routers, gateways, Ethernet switches and access points. At present, it has been widely used in the broadband access network system.

BCM53003B0KPB Network Processor has a 32-bit MIPS 3level pipeline processor core clocked at 600 MHz and provides a wide range of instruction set architectures, including MIPS16e2, 32R5/6/10/12/14, and also supports single-instruction multiple-data (SIMD) instruction set NEON instruction set. It provides 8K entries for look-up engine and supports eight banks for TCAM search (OTCM). At the same time, it also supports field matching of Layer 3 routing and provides up to 32K configurations for Layer 2 performance classification.

Moreover, BCM53003B0KPB Network Processor also provides a powerful embedded processor, which supports an independent 64-bit MIPS-compliant CPU, provides up to 128KB L2 cache, and can be used to perform traffic forwarding and flow control. In addition, the BCM53003B0KPB Network Processor core also contains a hardware acceleration engine, which consists of a set of channels, stateless blocks and look-up tables. Each channel is used to process specific packet fields, and the resulting data is transferred to the MIPS processor\'s data cache. This lets the processor core accelerate processing of up to 16 packets simultaneously in a single cycle, improving performance and reducing latency.

BCM53003B0KPB Network Processor supports up to 128 ports and up to 1 million connections per second. There are two kinds of ports: Ethernet ports and SSL ports. The Ethernet port provides 10/100/1000M full/half duplex auto negotiation, IEEE 1588 PTP support, VLAN identification scheme, QoS and other related functions to meet the requirements of ISPs and carriers. The SSL port supports encryption and decryption of packets, providing comprehensive security for network equipment.

The BCM53003B0KPB Network Processor\'s flexible and powerful instruction set allows customers to quickly develop products for specific standards. For example, support IPv4 and IPv6 dual-stack integrated, support 802.1d (multi-address domain) access and separation, support HaRP, support the four properties of NPU traffic control (network processor utilization, traffic policing and shaping, queue scheduling and load balancing), support up to 128k MAC address, and support link level encryption.

In conclusion, the BCM53003B0KPB Network Processor is an ideal solution for building high-speed, highly reliable, and cost-effective broadband access networks. Its rich instruction set and powerful hardware acceleration engine make it suitable for realizing network control, flow control, security control, packet processing, QoS, access authentication, and other functions. Besides, its flexible configuration ability enables customers to quickly develop products with specific requirements. It is no doubt that the BCM53003B0KPB Network Processor will be widely used in the medium-and high-end broadband access network system in the future.
