In addition, the BCM4710 provides simultaneous PCI 2.2 host interface, expansion host interface, and USB 1.1 host/ device interface operation for adding application specific peripherals. The BCM4710 represents the most comprehensive and flexible, low-cost, single-chip residential gateway platform with built-in home networking. MIPSTM core: The BCM4710 integrates an advanced custom 125 MHz MIPS32TM core with two-way set associative 8KB I-cache and 4KB D-cache and includes a 32x32-bit single-cycle multiply/accumulate function. In addition to all MIPSII instructions the MIPS core includes extra instructions for optimization of DSP algorithms for communications, audio, and video applications. A translation lookaside buffer MMU block is included, allowing support of all common real-time operating systems such as standard release Linux(R) (kernel 2.4.5 and greater) or VxWorks(R). Home networking function: The HomePNA 2.0 function integrated in BCM4710 provides 32Mbps maximum wire rate interface to home phone lines. Broadcom's iLine32TM implementation provides a robust implementation that interoperates with HPNA 1.0 devices and is dynamically rateadaptive between 32 Mbps and 1 Mbps. Broadcom(R), the pulse logo(R), iLine32TM and Connecting EverythingTM are trademarks of Broadcom Corporation and/or its subsidiaries in the United States and certain other countries. All other trademarks are the property of their respective owners. 10/100 Ethernet: The BCM4710 integrates two 10/100 Ethernet MACs, which is ideal for residential gateways that route and secure information between an Ethernet WAN port and one or more Ethernet LAN ports. PCI 2.2 host interface: The PCI host interface allows enumeration of two external PCI peripherals (more with external arbiter) for platform expansion. PCI adapters such as 802.11a, 802.11b and IPsec accelerators can easily be added to the system PCI. USB 1.1 host/device: The BCM4710 is capable of hosting two USB 1.1 compliant devices (two-port hub is integrated), allowing platform expansion by end users and can implement USB print server functionality. In addition, the USB interface can be configured as a USB device instead of a host to support direct connection to a PC USB port. Expansion bus: The expansion bus allows expansion of up to three devices without external address decode. The expansion bus can support a 16-bit PCMCIA host to third-party solutions for 802.11b, flash/compact flash, IDE, and generic 16-bit slave. Modem Function: The BCM4710 controller includes a data/fax/ voice modem interface to an external serial modem codec/DAA.
