Field Programmable Port Extender:
Fall 2001 Gigabit Workshop Tutorial

Overview

In this tutorial, you will learn how to accelerate the processing of packets in reprogrammable hardware using the Field Programmable Port Extender. These tutorials will focus on new applications and tools for the FPX, including the protocol wrappers, the KCPSM embedded active processor, the SDRAM Memory controller, and the NCHARGE control software. Participants will experiment with hardware/ software co-design through use of the FPX control software. In the programming laboratory, we will walk through the development of an actual module using the Xilinx FPGA design tools. Techniques of processing IP packets in hardware will be demonstrated.
