Techniques for processing transmissions in a communications (e.g., CDMA) system. A multithreaded processor processes a plurality of threads operating via a plurality of processor pipelines associated with the multithreaded processor and predetermines a triggering event for the multithreaded processor to switch from a first thread to a second thread. The triggering event is variably and dynamically determined to optimize multithreaded processor performance. The triggering event may be a dynamically determined number of processor cycles, the number being determined to optimize the performance of the multithreaded processor, or a variably and dynamically determined event, such as a cache or instruction miss.

L'invention porte sur des techniques de traitement de transmissions dans un système de communication (par exemple CDMA). Un processeur multifilière effectue le traitement d'une pluralité de fils fonctionnant par l'intermédiaire d'une pluralité de pipelines de processeur associés au processeur multifilière et prédétermine un événement de déclenchement afin que le processeur multifilière passe d'un premier fil vers un second fil. Cet événement de déclenchement est déterminé de manière variable et dynamique afin d'optimiser la performance du processeur multifilière. Cet événement de déclenchement peut être un nombre déterminé par voie dynamique de cycles de processeur, ce nombre étant déterminé de manière à optimiser la performance du processeur multifilière, ou un événement déterminé par voie dynamique, tel un manque de mémoire cache ou d'instruction.
