A System Implementing Multi-Threaded Applications

A method is provided for executing instructions embedded in two threads stored in a processing system comprising two operating units and a virtual managing entity for holding a plurality of queues for virtual objects waiting to use a respective operating unit and for diverting virtual objects from one queue to another. Each virtual object is associated with two virtual timers, one being a virtual timer for measuring a time period during which the virtual object is held in the queue (TIQ) and the other provides a period of time during which the virtual object will remain in an alive state (TTL). The method comprises: receiving information relating to virtual objects associated with the two threads; operating on virtual objects which their TTLs have expired; upon emerging from its respective queue, determining whether each virtual object should be diverted to another queue; upon diverting the virtual object, resetting its TIQ timer; and allocating an access time to each virtual object based on a number of threads requiring that virtual object and the TIQ associated therewith.
