Abstract

Next-generation wireless computing platforms will contain flexiblecommunications capabilites. At Rice University,the Rice Everywhere NEtwork (RENÉ) project is investigating a multi-standard, multi-tierintegration of W-CDMA cellular systems, high speed wireless LANs, and home wireless networks.There are many challenges in mapping these advanced communicationalgorithms to real-time hardware computing platforms.In this paper, we present current work on the developmentof a reconfigurable baseband physical layer containing DSP processorsand FPGA accelerators. Our goal is the design of amulti-tier network interface card (mNIC) which is capableof exploiting efficient, low-power reconfiguration.
