XLR732 and XLR716 Processors
Based on Broadcom's throughput-optimized multicore, multithreaded architecture, the XLR732 processor integrates 32 fine-grain threads using eight MIPS64® CPUs, while the XLR716 processor integrates 16 fine-grain threads using four MIPS64 CPUs. Both processors contain three full-speed on-chip interconnects, large multilevel caches, autonomous accelerators, quad memory controllers, native 10 Gigabit Ethernet MACs and other integrated I/Os.
The XLR® 700 series scalable communication processors from Broadcom are designed to address IP networking, VoIP, wireless LAN, 3G wireless, broadband, storage, routing and switching, security and telecommunication applications, along with the growing need to scale OEMs' software and hardware investments. The XLR732 and XLR716 processors integrate general-purpose processing, high-level programmability, scalability with thread processing, intelligent packet management, and the ability to combine control plane, data plane and security operations on a single processor.
