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:

  • The three Ethernet MAC interfaces each operate in 10/100/1000 Mbit/s and support industry standard MII (10/100 Mbit/s), GMII (1000 Mbit/s), and TBI (1000 Mbit/s) interfaces to standard Ethernet transceivers. Combinations of these Ethernet MAC interfaces can be bypassed to provide 8-bit, 16-bit, or 32-bit GPI interfaces.

  • The POS-PHY Level 3(TM) (PL3) and FIFO-like interfaces offer high bandwidth and easy to use interfaces running up to 200 MHz for connecting external packet processing FPGAs and ASICs.

  • An integrated 32-bit PCI controller provides PCI 2.1 compliant operation at both 33 MHz and 66 MHz.

  • An 8-bit HyperTransport interface that operates up to 500 MHz DDR.

  • A 200 MHz integrated DDR SDRAM interface provides 25.6 Gbit/s of memory bandwidth.

  • The local boot bus provides connectivity to lower speed devices such as boot ROM and Flash.

  • Operates from 0 to 70 degrees, consuming less than 7 watts of power.
