AMCC Unveils the PowerPC 460EX Embedded Processor

Applied Micro Circuits Corporation (AMCC) has announced the newest member of its embedded processor family of products, the PowerPC 460EX. Based on the Power Architecture standard, the 460EX is designed for a wide range of high performance applications including multifunction printing, networking, home gateway and general embedded processor requirements. Based on a 90 nm CMOS technology, the 460EX offers a significant increase in performance, increased memory capacity and bandwidth, standards-based connectivity, reduced power dissipation, and enhanced security processing acceleration. The 460EX is instruction set compatible with all other AMCC Power Architecture products and applications. The 460EX 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.

The Power Architecture core of the 460EX delivers a frequency ranging from 667MHz to 1.2GHz 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 an additional 64-Kbytes of on-chip memory mapped SRAM. The 460EX also supports up to four banks of DDR2 SDRAM memory and a maximum capacity of 16 Gbytes.

The 460EX features a wide range of peripheral integration and connectivity options. The processor has two independent PCI Express interfaces and a 32-bit PCI V2.3 interface; two integrated 10/100/1000 Ethernet ports with TCP/IP acceleration, quality of service and Jumbo Frame support; a USB 2.0 On-The-Go interface in addition to a separate USB 2.O Host Interface, an on-chip SATA controller and a 32-bit external peripheral bus interface. This is the first Power Architecture SoC design to include an integrated SATA controller to meet the growing demand of customers looking for integrated SATA disk drive connectivity.

The 460EX features a best-in-class Turbo Security Engine that supports standard security protocols such as IPSec, SSL and DTLS. The Turbo Security Engine attaches directly to the processor bus for the fastest possible system throughput. The engine also features Public Key Acceleration 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. The Turbo Security Engine is also designed to aid customers in complying with the proposed IEEE P2600 Standard for Information Technology: Hardcopy Device and System Security.

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 integrated into their products. The 460EX is designed to help customers meet these requirements. Typical power dissipation is an estimated 5W @ 1 GHz for the entire chip.
