The BCM5836P integrates an advanced, custom 264-MHz MIPS32 processor core, two 10/100 Ethernet MACs, and a high-performance SDRAM controller capable of operating at 133 MHz with either Double Data Rate (DDR) or Single Data Rate (SDR) SDRAM. For advanced security, the BCM5836P integrates an on-chip IPSec acceleration engine that can deliver up to 75 Mbps of single-pass AES/3DES encryption throughput and supports a broad range of industry-standard security features such as symmetric-key encryption and authentication algorithms including the latest 256-bit Advanced Encryption Standard (AES), Digital Encryption Standard (DES), 3DES, SHA-1, MD5, HMAC-SHA1, and HMAC-MD5. These features make this processor an obvious choice for SOHO/SMB networking customers who need both high bandwidth performance and advanced security features such as encryption and user authentication. The BCM5836P is capable of wire-speed Ethernet routing/bridging and possesses two-way set of associative 16-KB instruction cache, 16-KB data cache, and 1-KB prefetch cache. In addition to all MIPS instructions, the BCM5836P provides extra instructions that allow optimization of DSP algorithms for communications, audio, and video applications. An integrated MMU with a 32-entry TLB allows support of multithreaded operating systems such as standard distribution Linux operating system. The V.92 data/fax/voice modem interfaces to an external serial modem codec. The two 10/100 Ethernet MACs provide fail-over redundancy for interfacing to a switch device or wireless product. The PCI interface can also be used as a higher bandwidth interface in addition to the two MACs. The BCM5836P provides simultaneous PCI 2.3 host interface, external interface bus, and USB 1.1 host/device interface operation for adding application specific devices such as Broadcom's wireless processors. The PCI 2.3 host interface allows enumeration of three external PCI devices (more can be enumerated with an external arbiter) for platform expansion. The EBI allows expansion of up to four devices without external address decode. In summary, the BCM5836P 32-bit integrated processor is a flexible, low-power system-on-a-chip that is ideal for networking applications requiring security functionality. The BCM5836P features an integrated VPN hardware accelerator that is optimized for SOHO/SMB networked products.
