PMC-Sierra's RM9000x1GL family of single CPU core, MIPS-based microprocessors consists of the RM9120, RM9122 and RM9124. Main features include I/O interface options such as 3 ports of 10/100/1000 Ethernet MAC, Generic Packet Interfaces (GPI), and PCI or HyperTransport, while operating at under 7 watts. The RM9000x1GL microprocessors is aimed at a wide range of applications such as enterprise routers and switches, network protocol processing and conversion servers, storage systems, DSLAMs and Web servers. All three microprocessors are designed in 0.13 micron CMOS and operate from 0 to 70 degrees, consuming less than 7 watts of power in a typical application with all I/O running at maximum frequency.
The single-core microprocessors can also be used for VPN/Firewall and other security applications using either software encryption or an external hardware encryption engine.
"The highly integrated 1 GHz RM9000x1GL builds upon our successful RM9000x1 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
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 operates up to 500 MHz DDR. The local boot bus provides connectivity to lower speed devices such as boot ROM and Flash. And a 200 MHz integrated DDR SDRAM interface provides 25.6 Gbit/sec of memory bandwidth.
The RM9000x1GL microprocessors are available in three packages and will be sampling in the first quarter of 2004. The RM9120, RM9122 and RM9124 microprocessors are priced at $224, $209 and $249 respectively in 10KU quantities. Evaluation boards will also be available in the first quarter of 2004.
