Product Summary

The BCM4320SKFBG is an Intensi-fi Gigabit Ethernet Draft-802.11n Processor. It integrates a powerful 300 MHz/500 DMIPS (estimated) MIPS32 core with 4-way set associative 32 KB instruction cache, a 32 KB 2-way set associative data cache, and a 4 KB prefetch cache. An enhanced 10/100/1000 Gigabit Ethernet MAC controller with TCP Segmentation and checksum Offload (TSO) hardware acceleration engine substantially enhances system throughput.
