Mapping Wireless Communication Algorithms onto a Reconfigurable Architecture

Future mobile communication systems have to be flexible while adapting to environmental conditions and user demands. These systems also have to be energy-efficient as they are used in battery-operated terminals. We expect that heterogeneous reconfigurable hardware can overcome the contradicting requirements in flexibility, energy-efficiency and performance. A coarse-grain reconfigurable processor, called MONTIUM, is presented. An overview of a wireless LAN communication system, HiperLAN/2, and a Bluetooth communication system will be given. Possible implementations of these systems in heterogeneous reconfigurable hardware are discussed. Performance figures of the implemented HiperLAN/2 baseband processing in the MONTIUM architecture are presented. The required performance can be obtained at low clock frequencies with small configuration overhead. The flexibility of the MONTIUM is shown, as the baseband processing of both HiperLAN/2 and Bluetooth is implemented on the same architecture
