BCM1480 device MIPS64 processor core-based system-on-achip (SOC) that offers industry-leading performance, high functional integration, low-power levels required next-generation computing, storage, networking applications. BCM1480 scalable chip multiprocessor (CMP) system consisting four Broadcom SB-1 high-performance MIPS64 CPUs, shared 1-MB cache, memory controller, integrated I/O. major blocks processor connected together ZBbus, which high-speed, split-transaction multiprocessor bus. implements standard MESI protocol ensure coherency between four CPUs, cache, agents, memory. addition, BCM1480 supports interchip ccNUMA protocol cache coherent distributed shared memory systems. three high-speed ports provide interchip communications other BCM1480 processors bridging chips. Each port optionally configured SPI-4 Phase packet interface connectivity Gbps network devices. Four Gigabit-Ethernet MACs (10/100/1000) enable easy interfacing LANs control backplanes. enable higher data rates cases where Ethernet protocol processing required), Gigabit-Ethernet MACs configured 8-bit and/or 16-bit packet FIFOs. BCM1480 also integrates 64-bit, 133-MHz PCI-X local direct connection devices. Four serial ports available UARTs console ports.
enable low-chip count systems, BCM1480 also includes configurable generic that allows glueless connection boot flash memory simple peripherals. On-chip debug, trace, performance monitoring functions assist both hardware software designers debugging tuning system. system either big-endian little-endian mode. Implementation MIPS64 SB-1 core high-performance implementation standard MIPS64 that incorporates MIPS-3D MIPS-MDMX application-specific extensions (ASEs). core supports 4-issue enhanced skew pipeline dispatch memory (integer, floating point, MDMX, MIPS-3D) instructions cycle.
