PC/Server Based Architecture

„ Shared Bus / Interrupt / Interrupt Response Program —— bottlenecks!

„ A typical P4 Platform can only process up to 150,000/s packets

„ Applications moving to Giga-NI —— 1,500,000/s packets need to be processed in a 64byte packet environment!

Key points

„ CompactPCI and PICMG 2.16 is becoming a standard

platform for middle/high end communication

„ Value-added telecom equipments will be largely built

on the new standard platform

„ Embedded Processor and Network Processor are

becoming more and more important in Giga-level applications and next 10Giga-level applications

„ EmbedWay Focuses on Developing Embedded

Solutions for PICMG 2.16 and next generation 2.17、 ATCA…
