• Manufacturer Part Number: bcm5836p
• Description: Bcm5836p - Single-core 32-bit Mips Control Plane Processor With Pci
• Manufacturer: Broadcom Corp.

The BCM5836P processor is a flexible, low-power, single-chip
processor that integrates the most requested security features with wire-
speed performance, interfaces, and processing headroom to meet robust
applications such as SOHO routers, SMB routers and switches,
residential gateways, wireless access points, and VPN firewall
appliances.
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.
