XLP800 Series

XLP832 and XLP816 Multi-Core, Multi-Threaded Processor Family

Currently Viewing:

Third-generation architectural enhancement to Broadcom's industry-leading Multicore, Multithreaded XLR® Processor family.
The Broadcom XLP® 800 Series Processors are highly scalable devices that incorporate key functions of a high-end communication system, including wired and wireless security, networking, storage, data center acceleration, load balancing and other acceleration engines. The XLP 800 Series Processors are fabricated using 40 nm technology and offer processor core frequencies from 500 MHz to greater than 1.5GHz, providing a 3x performance-per-watt improvement over their XLR® predecessors. The XLP800 Series is software backward-compatible with the XLR and XLS® Processor families. The XLP800 Series includes:
XLP832 with 32 virtual CPUs
XLP816 with 16 virtual CPUs


  • With up to eight EC4400 Processor Cores that power the XLP800 Series, the processors provide optimum performance for both data plane and control plane applications. The EC4400 core architecture maintains the multithreading capability field-proven to provide the highest performance for throughput-oriented data plane processing
  • The XLP800 Series Processors contain a MOESI+ coherent, three-level cache architecture. Each one of the EC4400 cores contains a dedicated 64 KB instruction cache, a 32 KB L1 data cache and a 512 KB 8-way set-associative L2 cache
  • The XLP800 Series Processors contain a high-performance memory subsystem with four on-chip 72-bit DDR3 memory controllers with 51.2 GBps (Gigabytes per second) of bandwidth
  • A low-latency, high-speed Fast Messaging Network (FMN) allows for non-intrusive communication and control messaging among VirtuCores, acceleration engines, and I/O
