The
BCM5801
Cryptographic Processor integrates a high-
performance IPSec engine (DES, 3DES, HMAC-SHA-1,
HMAC-MD5), PCI interface and context buffer memory into a
single chip. Ideally suited for cost-sensitive client applications,
the
BCM5801
Cryptographic Processor offers tremendous
performance in a compact design. Offering hardware
acceleration for IPSec cryptographic functions makes the
BCM5801
an ideal solution for applications such as SOHO
routers and gateways, firewalls, VPN appliances, and network
interface cards.
The
BCM5801
provides complete 200-Mbps IPSec processing
(3DES, HMAC-SHA-1) performance in a highly integrated
design. The
BCM5801
offers a unique combination of
performance and cost-optimization by integrating the necessary
functional blocks into a single chip.
The
BCM5801’s
PCI interface makes it a perfect solution for all
cost-sensitive security applications. Requiring no external
components, the
BCM5801
is ideal for add-in card applications
requiring IPSec acceleration. A multi-threaded DMA engine
utilizes system memory to maximize throughput in real-world
applications. Unlimited security association (SA) support via
system memory, and the ability to pre-fetch packet contexts,
minimizes the performance degradation when processing small
packets.
Application program interface (API) support through
Broadcom’s Software Reference Library (SRL) for IPSec
application software offers
BCM5801
users a complete system
solution. Compatibility with industry-standard SSH IPSec
software eases integration and reduces time to market.
