MOTOROLA'S C-PORT™ FAMILY OF NETWORK PROCESSORS MOTOROLA'S C-PORTTM FAMILY OF NETWORK PROCESSORS 135 the C-Port C-5 NPU over the latter engine's ZBT SRAM port. The combination delivers significantly higher levels of search performance and throughput for mission-critical applications. To provide OC-48 rate classification of content based on layers 2 through 7 processing, the C-5 NPU can be inter- faced with the PM2329 ClassiPITM high-performance content processor from PMC-Sierra, with a specialized Software Development Kit (SDK) that is available from the latter engine as well. The PAX.portTM 2500 classification processor from Solidum is another classification processor that has been announced to be connectable to the C-5e in order to enable multigigabit processing (up to 2.5 Gbps). One of the most important elements in this teaming or alliance approach is the switch fabric. Motorola does not offer switch fabrics; It relies on relationships with other vendors. For example, IBM's PowerPRS fabric connects to the C-5 network processor through the IBM U-DASL interface, whereas the more recent IBM PowerPRS fabrics can connect to the C-5e directly through the CSIX- L1 interface. Besides the popular Software Development Environment (SDE) Tornado for Managed Switches (TMS 2.0), which is tightly integrated with the C-Port family development environment and is offered by WindRiver as the C-5 Switch Support Package (SSP), 4 Netplane's MPLS routing stack is also sup- ported. 5 HCL6 and Tality7 are two examples of other companies that offer expert design services for the C-Port network processor family, including hardware design and embedded
