方案描述：

Broadcom's BCM1125H product is a state-of-the-art processor solution targeted at the fast-growing networking, wireless communications, storage, server/networking appliance and imaging markets. BCM1125H processors offer industry-leading performance, high functional integration, and low power levels in a small package required by nextgeneration networking applications. The BCM1125H is software-compatible with the dual-processor BCM1250 and share development and modeling tools, firmware, and operating systems with the processor. The BCM1125H processors are intelligent systems on a chip consisting of a Broadcom SB-1 high performance MIPS64 CPU, a shared 256-KB L2 cache, a DDR memory controller, and an integrated I/O. All major blocks of the processor are connected together via the ZBbus, a high-speed, low-latency, splittransaction, memory-coherent bus. The bus implements the standard MESI protocol to ensure coherency between the CPU, L2 cache, I/O agents, and memory.
