Broadcom BCM4710 integrates 125-MHz MIPS32core along with HomePNA with Mbps phone line (iLine32TM) operation, 10/100 Ethernet MACs, modem codec interface. addition, BCM4710 provides simultaneous host interface, expansion host interface, host/ device interface operation adding application specific peripherals. BCM4710 represents most comprehensive flexible, low-cost, single-chip residential gateway platform with built-in home networking. MIPScore: BCM4710 integrates advanced custom MIPS32core with two-way associative I-cache D-cache includes single-cycle multiply/accumulate function. addition MIPSII instructions MIPS core includes extra instructions optimization algorithms communications, audio, video applications. translation lookaside buffer block included, allowing support common real-time operating systems such standard release Linux® (kernel 2.4.5 greater) VxWorks®. Home networking function: HomePNA function integrated BCM4710 provides 32Mbps maximum wire rate interface home phone lines. Broadcom's iLine32implementation provides robust implementation that interoperates with HPNA devices dynamically rateadaptive between Mbps Mbps.
