IRVINE, Calif. -- Broadcom Corporation (Nasdaq: BRCM), the leading provider of integrated circuits enabling broadband communications, today announced the Broadcom® BCM112x line of products, expanding its very successful SiByte™ family of high-performance, low-power, highly integrated processor solutions for networking, wireless communications, storage, appliance and imaging applications."The increase in Internet traffic coupled with demand for intelligent services such as policy-based Quality of Service (QoS) and security are driving the need for not only more processing performance, but deeper, more complex processing," said Dan Dobberpuhl, Vice President and General Manager of Broadcom's Broadband Processor Business Unit. "Broadcom's SiByte broadband processor products provide the necessary performance to process, manage and move data at very high line rates while minimizing power consumption and space requirements. After successfully delivering the BCM1250, we now offer, with the BCM112x, a way to extend these unique benefits to a wider range of high-volume applications, while leveraging existing software."The BCM112x line of products leverage the proven architecture of Broadcom's industry-leading BCM1250, the only MIPS®-based dual-core System-on-Chip (SOC) solution shipping in the market today. The BCM112x processors, with a single CPU, integrated memory controller and input/output (I/O), scale from 400 MHz to 1 GHz with power consumption starting at less than 4 Watts. The BCM112x products can perform wire-speed Layer 3 processing/routing in excess of 5 million packets per second. This processing performance allows the BCM112x, with two integrated 10/100/1000 Ethernet MACs, to support data rates of up to 2 Gbps.The first two new products within the BCM112x line are the BCM1125H and the BCM1125. Both devices feature the SiByte SB-1, a deeply pipelined 64-bit MIPS CPU that scales up to 1 GHz. In addition, both products integrate an on-chip 256KB L2 cache, a Double Data Rate (DDR) memory controller that supports up to 8 Gigabytes (GB) of memory and a variety of peripherals. The memory controller can be configured to use standard DDR SDRAM or FCRAM and provides up to 25 Gbps of peak memory bandwidth. The peripherals include two 10/100/1000 Ethernet MACs optionally configurable to one 16-bit or two 8-bit FIFO interfaces, a 32-bit 33/66 MHz PCI bridge, two serial interfaces, a generic bus for direct connection to boot flash, PCMCIA support and extensive on-chip debug features. All functional blocks of the processor are connected by the ZBbus, a 256-bit wide internal system bus that delivers up to 128 Gbps of on-chip bus bandwidth, eliminating the bus as a potential bottleneck in real-world applications. The ZBbus is based on sophisticated circuit design techniques that achieve very low data transfer latency without the complexities of alternative switch-based architectures.Broadcom Corp.
