I/O Processor

I/O Overview

Intel
® I/O processors are highly integrated microprocessors that provide a processor core and high-speedperipherals to build devices that need high I/O throughput. Intel’s I/O processors are found in many storage, networking, and embedded communications applications. They feature high-speed PCI buses and memory controllers as well as the highest performing Intel XScale
® microarchitecture-based processor cores. There is a wide range of I/O processors to meet cost, power, performance and component-sizing needs.

FeaturesBenefits

I/O Processing Performance
â–  Offloads I/O processing functions,such as I/O interrupt processing and parity calculations from a host processor.I/O processors are also excellent general-purpose processors for high-bandwidth applications that require integrated processors with low power consumption and high-speed peripherals.Intel XScale
® Microarchitecture
â–  Intel’s groundbreaking new microarchitecture provides very highprocessor performance with extremely low power consumption. Intel XScale technology provides the platform for the most advanced designs in storage,infrastructure and embedded communications.Integrated Designs
â–  I/O processors are available in single- or dual-chip configurations.This provides developers with pre-validated component sets, simplified board designs,and board-space cost savings.Comprehensive Set of Development Tools
â–  Faster time-to-market and support for multiple tool-chains and operating systems on the Intel XScale microarchitecture.
