San Jose, CA; Communications Design Conference — (press release excerpt) — Motorola Computer Group today launched the Packet Computing Resource Board (PCRB), a high-density CompactPCI blade for high speed processing of packet data typical in today's networking systems. The PCRB is a highly integrated and optimized multi-processing resource for packet data intensive applications such as content-aware… switches, IP services gateways, 3G radio network controllers, IP control servers, VPN switches/routers, and content-feature server switches. The PCRB is supplied with a Linux board support package and a Linux cross development environment.

Gigabit Ethernet connections on Motorola's PCRB support the CompactPCI Packet Switched Backplane standard (CPSB or PICMG 2.16) to distribute multiple high speed packet streams throughout an equipment shelf. Two high performance, integrated 64-bit multiprocessors — supported by high speed DDR SDRAM — enable the PCRB to process packets at an extremely high speed. An on-board layer 2/3 Ethernet switch connects the processors' multiple Gigabit Ethernet interfaces, the CPSB interfaces and rear transition module interfaces allowing eight classes of service on an aggregate switching capacity of 32 million packets per port.

The PCRB complements Motorola's MXP platform, an embedded applications platform that delivers multiple services that can connect to different telecom networks. The company also recently introduced a Packet Processor Resource Board (PPRB), which adds a network processor subsystem to the MXP platform, enabling it to manage data as control plane traffic and to process the data as bearer plane traffic at wire speed in its native packet format.
