This document provides an overview of the IXA SDK 3.5 simulation environment and programming models. It discusses how the SDK provides packet simulation options and code for basic router functions like receive, process, and transmit. Specifically, it presents code snippets for a static forwarding application built from microblocks and core components that are executed across multiple microengines and an XScale core.

14. Receive Process and TransmitReceive Process and Transmit
• A router performs three basic operations
on the packets.
 Receive, Process and Transmit.
• Intel IXA SDK provides tested Receive
and transmit code which only requires
change when the hardware changes.
• Process tasks- May vary from simple
packet counting to complex tasks.
