Abstract
Methods and apparatus provide for a busy resource encoder to allow for a finer control of spin versus yield decisions. Specifically, the busy resource encoder allows for the execution a first thread, where the first thread is using a particular resource. Additionally, the busy resource encoder allows for the execution of a second thread, where the second thread requires use of the resource which is locked due to first thread execution. The busy resource encoder creates a busy code to indicate the progress of the execution of the first thread in relation to use of the resource by the first thread. The second thread can then read the busy code to determine to execute one of a spin and a yield routine by the second thread.
