Routing on a two-dimensional torus architecture by means of the wormhole routing algorithm is introduced and extended to an n-dimensional torus model. To prevent blocking deadlocks caused by this algorithm, a multiple virtual channel solution is introduced. An implementation of virtual channels is introduced that allows channels with higher labels to pre-empt 'lower' channels. This algorithm is tested with a simplified model of a HiperLAN/2 receiver. The model proves to be capable of running this application on the Chameleon architecture according to http://chameleon.ctit.utwente.nl/.
