BCM4706 - Intensi-fi® 802.11n GbE Processor

The Broadcom BCM4706 is a high performance, power efficient communications processor designed for WLAN router and access point applications.

The BCM4706 integrates a powerful 600 MHz MIPS32 74K superscalar CPU with gigabit MAC and supports high-speed I/O interfaces
including DDR2 and PCIe. The BCM4706 also integrates a USB2.0 host controller to connect to external USB storage devices.

Features

• MIPS32® 74K Core (600 MHz)
• Integrated 512 KB Fast Net RAM
• Serial/parallel and NAND flash memory support
• Gigabit ethernet (GbE) Media Access Control (MAC) with support for GMII, RGMII, and MII PHY/switch connectivity
• Dual PCIe interfaces to pair with BCM4331 802.11n 3x3 Wi-Fi® chips in selectable dual-band and simultaneous dual-band configurations

This is CPU and memory benchmark for OpenWRT v0.6. This will then take some time... (typically 30-60 seconds on a 200MHz computer)
Overhead for getting time: 22us
Time to run memory bench: 2.04[secs]
Time to run computation of pi (2400 digits, 10 times): 5.42[secs]
Time to run computation of e (9009 digits): 4.37[secs]
Time to run float bench: 2.12[secs]
Total time: 13.9s
