Quad-Core 64-bit MIPS® Processor with DDR2, GbE, SPI-4/HT
The BCM1480 device is an MIPS64 processor core-based system-on-achip (SOC) that offers industry-leading performance, high functional integration, and low-power levels required by next-generation computing, storage, and networking applications.
The BCM1480 is a scalable chip multiprocessor (CMP) system consisting of four Broadcom SB-1 high-performance MIPS64 CPUs, a shared 1-MB L2 cache, a DDR memory controller, and integrated I/O. All major blocks of the processor are connected together via the ZBbus, which is a high-speed, split-transaction multiprocessor bus. The bus implements the standard MESI protocol to ensure coherency between the four CPUs, L2 cache, I/O agents, and memory. In addition, the BCM1480 supports an interchip ccNUMA protocol for cache coherent distributed shared memory systems.
