BCM5801 Cryptographic Processor integrates highperformance IPSec engine (DES, 3DES, HMAC-SHA-1, HMAC-MD5), interface context buffer memory onto single chip. Ideally suited cost-sensitive client applications, BCM5801 Cryptographic Processor offers tremendous performance compact design. Offering hardware acceleration IPSec cryptographic functions makes BCM5801 ideal solution applications such SOHO routers gateways, firewalls, appliances, network interface cards. BCM5801 provides complete Mbps IPSec processing (3DES, HMAC-SHA-1) performance highly integrated design. BCM5801 offers unique combination performance cost-optimization integrating necessary functional blocks into single chip.
BCM5801's interface makes perfect solution cost-sensitive security applications. Requiring external components, BCM5801 ideal add-in card applications requiring IPSec acceleration. multi-threaded engine utilizes system memory maximize throughput real-world applications. Unlimited security association (SA) support system memory, ability pre-fetch packet contexts, minimizes performance degradation when processing small packets. Application program interface (API) support through Broadcom's Software Reference Library (SRL) IPSec application software offers BCM5801 users complete system solution. Compatibility with industry-standard IPSec software eases integration reduces time-to-market.
