AMCC Announces a New Member of its Power Architecture Processor Family Targeted for Wireless Infrastructure and Enterprise Networking Applications

Applied Micro Circuits Corporation (NASDAQ: AMCC), a global leader in embedded Power Architecture™ processing, optical transport and storage solutions, announced the newest member of its embedded processor family of products, the PPC460GT. The announcement is being made at this week’s Power Architecture Developer Conference in Austin, Texas, where AMCC is a Platinum Sponsor. Based on the Power Architecture standard, the PPC460GT is designed for a wide range of high performance applications including wireless infrastructure and enterprise networking. "The throughput and data processing requirements of next generation wireless infrastructure and enterprise equipment continue to grow,” said Sam Fuller, Vice President of Marketing for AMCC. "The AMCC PPC460GT integrates a high-performance Power Architecture CPU core with important peripheral interfaces like Serial RapidIO (SRIO), PCI Express® and Gigabit Ethernet. Advanced security processing features including IPSec, SSL and the KASUMI encryption algorithm are also integrated into this low power, low cost system-on-a-chip solution (SoC). This new embedded processor further enhances AMCC’s reputation as a leading innovator and product supplier in the Power Architecture market.” The PPC460GT features a SoC platform based on the Power Architecture standard that delivers clock speeds exceeding 1 GHz, along with increased memory interface performance, advanced connectivity, reduced power dissipation, security processing acceleration and a smaller form factor. The PPC460GT is instruction-set compatible with all other AMCC Power Architecture products, and applications can be easily migrated from both AMCC processors and those of other Power Architecture vendors in order to deliver upgraded performance and functionality to product designers and engineers. "We are pleased to see other processor providers support the use of Serial RapidIO for computationally intensive applications such as 3G/3.5G and WiMAX™ wireless base stations,” said Alan Gatherer, CTO at Texas Instruments Wireless Infrastructure Group. "As an early adopter of SRIO technology on our infrastructure-optimized single and multi-core digital signal processors, TI and its OEM customers agree that this connectivity solution offers measurable improvements to processor performance and overall system-level efficiency.” Performance The superscalar Power Architecture core of the PPC460GT delivers a frequency ranging from 667MHz to 1.2 GHz with 2.0 Dhrystone MIPS/MHz. This processing throughput is significantly higher than is available from most competitive core offerings. Extensive memory support includes 32-Kbyte Instruction and Data Caches, an on-chip 256-Kbyte L2 cache and additional 64-Kbytes of on-chip memory mapped SRAM. The PPC460GT also supports up to four banks of ECC protected DDR2 SDRAM memory with a maximum capacity of 16 Gbytes. Connectivity The PPC460GT features a wide range of peripheral integration and connectivity options. The processor has an x4 SRIO port, two independent PCI Express interfaces, a 32-bit PCI V2.3 interface and a 32-bit external peripheral bus interface. The PPC460GT offers four integrated 10/100/1000 Ethernet ports, two with TCP/IP acceleration, quality of service (QoS) and Jumbo Frame support with broad connectivity options including SGMII. Security The PPC460GT features a best-in-class Turbo Security Engine that supports standard security protocols such as IPSec, SSL and DTLS. KASUMI encryption is also available to support wireless infrastructure applications. The Turbo Security Engine attaches directly to the processor bus for the fastest possible system throughput. The engine also features Public Key Accelerator and True Random Number Generation, as well as full header/trailer protocol processing. It is compliant with FIPS-140-2 and ANSI X9.17 Annex C and is also designed to aid customers in complying with the proposed IEEE P2600™ Standard for Information Technology: Hardcopy Device and System Security. Power OEMs face increasingly stringent energy and power requirements for their products in order to meet ENERGY STAR™ and similar guidelines set by the EPA and other government organizations. They are seeking reduced power demands from every component that is integrated into their products. The PPC460GT is designed to help customers meet these requirements. Typical power dissipation is estimated to be 6W @ 1 GHz. AMCC will begin product sampling in the fourth quarter of 2007. Distributor suggested resale pricing starts at $55 in 25k quantities. AMCC's Power Architecture processors are supported by AMCC and more than 50 partners who provide a full range of software, boards and development tools necessary for manufacturers to develop products quickly and efficiently.
