Single-Core Processor for Control Plane Applications
Broadcom's BCM1122 is a state-of-the-art processor solution targeted at the fast-growing networking, wireless communications, storage, server/networking appliance and imaging markets. The BCM1122 offers industry-leading performance, high functional integration, and low power levels in a small package required by next-generation networking applications.
The BCM1122 is software-compatible with the BCM1125H and the dual-processor BCM1250 and share development and modeling tools, firmware, and operating systems. The BCM1122 is an intelligent system-on-a-chip consisting of a Broadcom SB-1 high performance MIPS64 CPU, a shared 128-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, split-transaction, memory-coherent bus. The bus implements the standard MESI protocol to ensure coherency between the CPU, L2 cache, I/O agents, and memory.
