SANTA CLARA, Calif. -- PMC-Sierra(TM), Inc. (NASDAQ:PMCS) announced the RM9000x1GL(TM) family of highly integrated 1 GHz 64-bit MIPS-based(TM) microprocessors. The RM9000x1GL family of single CPU core microprocessors consisting of the RM9120(TM), RM9122(TM) and RM9124(TM) offer customers I/O interface options such as 3 ports of 10/100/1000 Ethernet MAC, Generic Packet Interfaces (GPI), and PCI or HyperTransport(TM) while operating at under 7 watts. As a result, the RM9000x1GL microprocessors can be used in a wide range of applications such as enterprise routers and switches, network protocol processing and conversion servers, storage systems, DSLAMs and Web servers. The single-core microprocessors can also be used as a high-performance and compact solution for VPN/Firewall and other security applications using either software encryption or an external hardware encryption engine for the highest performance applications.

"The highly integrated 1 GHz RM9000x1GL builds upon our successful RM9000x1(TM) MIPS-based single CPU core architecture providing customers with a low power, low cost solution for applications requiring high connectivity but without dual-CPU processing requirements," said Tom Riordan, vice president and general manager of PMC-Sierra's Microprocessor Products Division. "PMC-Sierra offers the industry's most scalable, stand-alone MIPS-based microprocessors and we are committed to extending our RM5200(TM), RM7000(TM) and RM9000(TM) families with higher integration and performance while maintaining low power."

The RM9000x1GL integrates high-speed memory and I/O interfaces to enable both low latency memory access by the CPU and high bandwidth access by the I/O devices. The I/O interfaces include three Ethernet MACs, PCI or HyperTransport, DDR SDRAM controller, SysAD and a local boot bus:
