PMC-Sierra Unveils High Integration 1 Gigahertz Single-CPU 64-Bit MIPS

10/28/2003 - PMC-Sierra(TM), Inc. (Nasdaq: PMCS - News) 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."

Integrates High-Speed Memory and Multiple I/O Interfaces
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:

Pricing, Availability and Customer Support
The RM9000x1GL microprocessors are available in three packages (see Table 1) and will be sampling in the first quarter of 2004. All three microprocessors are designed in 0.13 micron CMOS and draws less than 7 watts in a typical application with all I/O running at maximum frequency. The RM9120, RM9122 and RM9124 microprocessors are priced at $224, $209 and $249 respectively in 10KU quantities. For more information about pricing and availability, contact a PMC-Sierra sales representative at Evaluation boards will also be available in the first quarter of 2004.

RM9000 MIPS-based Microprocessors Compatible with Industry Standards
The MIPS® architecture has become one of the most widely licensed, open-industry standard architectures in networking, networked printer and networked consumer applications. A wide range of development tools and resources are available through a large number of third-party development partners. The RM9000 family of microprocessors supports multiple operating systems including Linux and Wind River's VxWorks®. A variety of packaged systems for software development or for full product deployment are currently available through Momentum Computer. These packaged systems provide operating systems, compilers, debuggers, RTOS and peripheral support for HyperTransport. The on-chip EJTAG debug module ensures smooth and easy debugging of both hardware and software by allowing a single step and state examination.
